Vitamin D Helps Combat the Covid-19 Coronavirus

An article in the Lancet describes that vitamin D helps combat the Covid-19 coronavirus. A publication in the Lancet (diabetes and endocrinology) on Aug. 3, 2020 reviewed randomized controlled trials between 2007 and 2020. The authors of the study wanted to see whether vitamin D had curative effects on Covid-19 coronavirus infections. Indeed, Dr. Adrian R Martineau and Dr. Nita G Forouhi pointed out that researchers examined vitamin D already in the 1930’s. In other words, at that time they showed that supplementation with cod liver oil prevented absenteeism in various industries. Notably, the active ingredient in cod liver oil was later found to be vitamin D. Vitamin D stimulates the immune system to overcome flu infections.

How Vitamin D overcomes Covid-19

The meta-analysis by Dr. Adrian R Martineau and Dr. Nita G Forouhi showed that vitamin D has several effects on Covid-19. In the early stages vitamin D stimulates host responses of the immune system against SARS-CoV-2 (= Covid-19 coronavirus). This involves the release of antimicrobial peptides, which have powerful antiviral effects making it more difficult for the virus to attack. Other publications showed that vitamin D stimulates autophagy, the process of “self-eating”. Cells that have been damaged by the virus or due to older age are removed by phagocytizing cells (monocytes, macrophages). This allows for new cells to take the place of the damaged cells.

Symptoms of Covid-19 are similar to the symptoms associated with vitamin D deficiency. Certain population groups are at a bigger risk, including older persons, obese individuals and persons Black ethnic or Asian ethnic background.  Several studies showed that supplementation with vitamin D3 became protective, preventative and therapeutic against Covid-19.

Vitamin D has specific effects

There are three major effects that vitamin D has.

  1. A strengthening of the epithelial barrier not allowing the coronavirus to penetrate into the lung tissue as easily.
  2. Release of defensins and cathelicidin, two crucial antiviral polypeptides that eradicate any virus in the system.
  3. Interruption of the “cytokine storm”, which is responsible for viral pneumonia to develop. Without the cytokine storm there is no damage to the lungs and people do not need treatment in the ICU. This is particularly important for people above the age of 60 and for people with pre-existing diseases.
  4. With the stabilizing effect of vitamin D regarding the immune function more severe forms of Covid-19 can turn into less severe forms with a better outcome.

Severe Covid-19 cases and vitamin D blood levels

There were two studies that have indicated that low vitamin D blood levels have a strong association with severe cases of Covid-19.  Extremely low vitamin D blood levels were found in severe Covid-19 cases in Spain, Italy and Switzerland. .

The authors concluded that any case of Covid-19 should receive adequate vitamin D3, but it is particularly important to the severe cases.

Two facts evolved from these studies: first, with low vitamin D blood levels there is a greater susceptibility to get Covid-19. Secondly, Covid-19 severity increases when the patient has low vitamin D blood levels.

What levels of vitamin D in the blood are required to fight Covid-19 coronavirus?

Vitamin D is very important for the integrity of the immune system. With  vitamin D blood levels below 15 to 20 ng/mL (37.5–50 nmol/L) there is a paralysis of the  immune system. Any viral or bacterial infection tends to overwhelm the body. This is the reason why the mortality due to Covid-19 coronavirus is highest in patients with these low vitamin D blood levels. People with secondary illnesses (diabetes, arthritis, autoimmune diseases, cancer) and patients above the age of 60 are at the highest risk. They have the lowest vitamin D blood levels and have the highest mortality rates. This publication describes this in more detail: Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths.

Above a vitamin D blood level of 30 ng/mL (=75 nmol/L) a patient’s immune system is functioning normally. However, the immune system is strongest at a vitamin D blood level of 50–80 ng/mL (125–200 nmol/L), which is the upper range of the normal level for vitamin D in the blood.

Keep in mind that vitamin D toxicity occurs only above 150 ng/mL (375 nmol/L). There is a wide margin of safety between 80 ng/mL (200 nmol/L, which is the upper range of normal) and the toxic level, which is 150 ng/mL (375 nmol/L). In any case it is important to have a blood test which gives information about the vitamin D3 blood level.

Vitamin D Helps Combat the Covid-19 Coronavirus

Conclusion

A new publication in the Lancet (diabetes and endocrinology) performed a meta-analysis of randomized controlled trials between 2007 and 2020. The authors found that a low blood level of vitamin D predicts that these patients are in trouble. They will have a severe form of Covid-19 when they get exposed to the coronavirus, SARS-CoV-2. Patients with higher normal vitamin D blood levels (50–80 ng/mL or 125–200 nmol/L) get very few symptoms of Covid-19 and have a low mortality. The reason is that their immune system is strong and they wall off the coronavirus at the epithelial barriers. Their immune system also releases polypeptides that eradicate the virus in the system. In addition, the “cytokine storm”, which is responsible for viral pneumonia is interrupted by vitamin D. Without the cytokine storm there is no damage to the lungs and people do not need treatment in the ICU.

Supplementation with vitamin D3 is safe

It is safe to supplement with vitamin D3 to bring the blood level into the upper range of normal. This keeps the immune system at its optimal functional level. There is a wide margin of safety between 80 ng/mL (=200 nmol/L, which is the upper range of normal) and the toxic level, which is 150 ng/mL (375 nmol/L).

Adequate Vitamin D Level Strengthens the Immune System

The Covid-19 coronavirus crisis is teaching us that an adequate vitamin D level strengthens the immune system.

When we age, our resistance to infections weakens, but this may be because our immune system needs more vitamin D3. I have reviewed the super powers of vitamin D3 before in 2014. In the past the thought was that the human body would need only 400 IU of vitamin D3 every day to cure rickets. And these were the daily vitamin D3 recommendations from medical authorities for several decades. Gradually it became known that for cancer prevention, infection prevention, cardiovascular illness prevention and for diabetes prevention much higher doses of vitamin D3 were necessary. As pointed out in the previous link, almost 50% of the world population is deficient in vitamin D. This is due to a lack of exposure to sunlight and due to inadequate supplementation with vitamin D3.

History of vitamin D

Dr. Adolf Windaus received the Nobel prize for chemistry in 1928. It was to acknowledge “… his studies on the constitution of the sterols and their connection with vitamins”. His work involved the metabolism of vitamin D and the precursors of vitamin D.

Rickets

As the above link shows, rachitic children were treated since the mid 1800’s with cod liver oil and since the early 1900’s also with ultraviolet light. But we know now that 400 IU of vitamin D3 per day is just enough to cure rachitic children, but it is not enough to strengthen the immune system to fight influenza viruses or the Covid-19 coronavirus. I will discuss further below what vitamin D blood levels are important to achieve a healthy state of the immune system.

Adequate vitamin D level strengthens the immune system

The immune system is very complicated and consists of many cell types that interact with each other and the rest of the body. It is important to recognize that the innate immune system immediately inactivates intruding viruses. But the vitamin D blood concentration has to be high enough. The acquired immunity consists of antibodies that are produced by B cells. The antibodies were produced during prior infections that you have survived and you are now immune to. However, other antibodies that circulate in your blood may have originated from vaccines you received in the past (whooping cough, measles, tetanus, diphtheria etc.). With the Covid-19 coronavirus it is the innate immunity that plays the biggest role until a vaccine will be found in the future.

Vitamin D is a hormone

This 2013 paper explains that vitamin D is a hormone that stimulates its own vitamin D receptor. This is a nuclear receptor that has close relations to the cell DNA and can stimulate more than 900 polypeptides. They are messenger molecules that are involved in a variety of physiological functions. One of the key functions is the immune system. This link explains that T cells that have vitamin D receptors can develop into cytotoxic T cells (also known as “killer T cells”). They are important in fighting cancer, but also parasites.

The key is that the hormone vitamin D can release more than 100 polypeptides that have the power to fight virus attacks including the Covid-19 coronavirus.

Three mechanisms how vitamin D works against the virus

The researchers outlined 3 mechanisms of how vitamin D works:

  • Maintaining tight epithelial junctions making it more difficult for the Covid-19 coronavirus to penetrate.
  • “Killing enveloped viruses through induction of cathelicidin and defensins.” These powerful antiviral polypeptides can kill viruses that have invaded the blood stream within 1 to 2 days.
  • “…And reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia.” It is people who get the viral pneumonia that are at a high risk of death. By bringing the blood level up to the higher range of normal, between 50 and 80 ng/mL, patients that have encountered Covid-19 coronavirus are more likely to survive.

Two polypeptides, cathelicidin and defensins

Again, I like to emphasize that it is not vitamin D that has a direct effect on the virus. It is two polypeptides, cathelicidin and defensins, which are powerful antiviral polypeptides, that are released by vitamin D.

They can kill viruses that have invaded the blood stream and can eliminate the cytokine storm. This all happens very fast, within only 1 to 2 days. But you have to have an adequate vitamin blood level for this to occur (about 50-80 ng/mL).

Sources of vitamin D

First of all, vitamin D is readily absorbed from food. But there are not many foods that contain enough vitamin D for the immune system. The ones that contain vitamin D are as follows:

  • “Fatty fish, like tuna, mackerel, and salmon.
  • Foods fortified with vitamin D, like some dairy products, orange juice, soy milk, and cereals.
  • Beef liver.
  • Cheese
  • Egg yolks. “

Sun induced amount of vitamin D

Secondly, vitamin D can be synthesized in the skin from exposure to sunlight. But for this to happen all the necessary enzymes need to be present.  This link explains that many older people above the age of 65 have low vitamin D blood levels because of a lack of sun exposure and a lack of cutaneous synthesis because of enzyme issues.

Vitamin D supplements

The most reliable source of vitamin D are vitamin D3 supplements. When people supplement with the same dose of vitamin D3 there will be people who get higher vitamin D blood levels than others, as absorption in the gut is different for different people.  The ones who have relatively low vitamin D blood levels are often called “slow vitamin D absorbers”. But when the vitamin D3 dosage is increased even those people will reach the recommended high normal range (50-80 ng/mL).

Vitamin D blood level

The vitamin D blood test has the scientific name “25-hydroxy vitamin D level”. This is now the recognized gold standard for determining who is deficient or has normal levels with respect to vitamin D. The following 2013 publication has studied the vitamin D level of 1,470 healthy Swiss men and women, 60 years or older. Vitamin D levels were classified as severely deficient when the level was below 10 ng/mL. The vitamin D level was deficient between 10 and 20 ng/mL. The level was insufficient when between 21 and 29 ng/mL. A level above 30 ng/mL is normal.

8 % of the subjects were severely insufficient and 66% had insufficient vitamin D levels. Only 26.1% of the subjects had normal levels. Over 50% of healthy older Swiss (above the age of 70) had insufficient vitamin D levels.

Which vitamin D level is safe and which is not?

A peer-reviewed publication of the effects of vitamin D in health and disease contains 269 references.

What vitamin D level is optimal? This question was reviewed in this paper.

  • Below 15 ng/mL the immune system is paralyzed
  • With a level above 30 ng/mL the immune system is working
  • A level of 50-80 ng/mL has the immune system working optimally
  • Above 150 ng/mL toxic vitamin D levels start
  • With 300 ng/mL severe toxicity begins

Vitamin D toxicity

It is only with high levels of vitamin D (more than 150 ng/mL) that you have to worry about high calcium levels in the blood or kidney stones (toxic levels). But the key is to not exceed 80 ng/mL regarding the vitamin D blood level. This gives you a lot of flexibility before you reach toxic levels (above 150 ng/mL). For those who want more information, here is a thorough, peer reviewed publication about vitamin D toxicity with 59 references.

Vitamin D supplement compliance

The question is why not more people take adequate vitamin D3 supplements.  We know that vitamin D can prevent so many chronic diseases including serious viral infections. The answer is complex, but it includes a fear of the population of vitamin toxicity (kidney stone and high calcium levels). However, as pointed out before, this occurs only above a vitamin D level of 150 ng/mL. With proper vitamin D blood level monitoring you never reach toxic levels of vitamin D.

Denial

Denial likely is another major factor. People feel that if they have a balanced diet, they would be protected from vitamin D insufficiency. As pointed out before this is a grave error to think as our food does not contain sufficient vitamin D to strengthen our immune system.

False security with low doses of vitamin D

Finally, there are people who think that low doses of vitamin D, like 1000 IU of vitamin D daily, would be enough. But it is not enough. This is why testing vitamin D blood levels is so important. It is a reality check. The blood level must be in the high normal range (50-80 ng/mL). At this level the immune system functions optimally.

Compliance issues

In this context there was an interesting study done by LifeExtension, a company that publishes monthly health magazines. In this study the company examined the vitamin D blood levels of LifeExtension members. They are the ones who should be knowledgeable in how important it is to have good, preventative vitamin D blood levels. The study showed that 38% of the vitamin D test results were less than 30 ng/mL. In addition, 69% of the vitamin D tests were less than 40 ng/mL. Finally, 85% of the vitamin D test results were less than 50 ng/mL. What this means is that LifeExtension members were non-compliant when it came to taking regular adequate vitamin D3 doses. This resulted in levels that were too low for the majority to protect them from the Covid-19 coronavirus.

Covid-19 coronavirus infections and vitamin D blood level

There is a tight relationship between vitamin D blood levels and the strength of the immune system. Essentially, coronavirus mortality measures who is vitamin D deficient. Without enough vitamin D on board the virus penetrates into the blood stream and penetrates the lining of the respiratory tract. Next the cytokine storm develops, which leads to viral pneumonia. Higher doses of vitamin D3 will mitigate the course of Covid-19 coronavirus.

Adequate Vitamin D Level Strengthens the Immune System

Adequate Vitamin D Level Strengthens the Immune System

Conclusion

The Covid-19 coronavirus pandemic has taught us how important an intact immune system is to survive the virus when you get it. We do know for some time how closely related a good vitamin D level is with the functioning of the immune system. I have reviewed here what a desirable vitamin D level is and how we can achieve this with oral vitamin D3 supplements. The goal is to achieve a vitamin D level in the upper range of normal (50-80 ng/mL). With a level like this the virus cannot penetrate the mucous membranes of the respiratory tract and even if it did, it cannot produce a cytokine storm in the blood that would lead to the deadly viral pneumonia or to blood clots. When the virus invades the bloodstream, vitamin D releases powerful antiviral polypeptides that can kill viruses within 1 to 2 days.

Here are some peer-reviewed publications on vitamin D:

Vitamin D Is the Definitive Link

Vitamin D deficiency caused rickets in the past, but now we know that vitamin D is the definitive link for other health problems. The lack of it is the reason for numerous illnesses. A search in my website gives you more than 170 blogs where I am discussing the effect of vitamin D. These describe how vitamin D is the definitive link in a lot of different diseases. In a 2015 study from Brazil the authors noted that a critical vitamin D blood level was 12 ng/mL. All these critically ill patients received treatment in an ICU setting. In vitamin D blood levels of 12 ng/mL the mortality rate was 32.2%. A control group of ICU patients with more than 12 ng/mL had a mortality rate of only 13.2%. The authors concluded that a low vitamin D level on ICU admission was an independent risk factor for mortality in this critically ill patient group.

A few diseases where low vitamin D is the definitive link for a poor outcome

In patients, who have arthritis, cardiovascular disease, breast cancer, diabetes, osteoporosis, influenza and others, the laboratory tests that shows their 25-hydroxy vitamin D level, are usually below 15 ng/mL. This link has 269 peer reviewed references.

2015 Italian study showed that microvascular complications in diabetes patients were high, if the vitamin D3 blood levels were low. If patients had high levels of vitamin D, there were no complications such as retinopathy or nephropathy. But if levels were below 20 ng/mL, damages were significant in the capillaries of the eyes and kidneys.

Multiple sclerosis

It has been known for some time that in the northern hemisphere MS is more common because of the lack of sunshine, which in turn leads to less vitamin D3 production in the skin. Multiple sclerosis (MS) is an autoimmune disease where immune cells attack the lining of nerves. Both nerve cells and immune cells have vitamin D receptors. It appears that vitamin D calms down immune cells and remission of an MS relapse is more likely.

Dr. Fitzgerald and colleagues published a study in JAMA Neurology in 2015. Results of this study showed marked differences between MS patients with high and low vitamin D levels.

Multiple sclerosis rates with high and low vitamin D levels

Patients with the highest vitamin D blood levels (more than 40 ng/mL) had the lowest rates of new MS lesions. Previous studies found that a low blood level of vitamin D (less than 25 ng/mL) had an association with a higher risk of developing MS. Dr. Fitzgerald’s study showed that a 20 ng/mL (50.0-nmol/L) increase in serum vitamin D levels associated with a 31% lower rate of new MS lesions. Patients with the highest vitamin D level of more than 40 ng/mL (100 nmol/L) had the lowest amount of new MRI lesions (47% less than the patients with the lowest vitamin D levels).

Dementia and Alzheimer’s disease

A 2014 study showed that patients with a low vitamin D level had a connection with a high risk of dementia and Alzheimer’s disease.

Specifically, the researchers found the following observations.

  • Vitamin D level of less than 10 ng/mL: 122% increased risk of Alzheimer’s
  • A vitamin D level of 10 to 20 ng/mL: 51% increased risk of Alzheimer’s

Vitamin D is the definitive link for the immune system

In a publication of 2006 Dr. John Cannell and co-workers have reviewed why influenza has seasonal outbreaks. They found that the innate immune system was very dependent on vitamin D. Those who did not get enough sunlight in the northern hemisphere during January, February, March and April have an average 25-hydroxy vitamin D level of only 15 to 17 ng/mL. In contrast, from July to September the same volunteers had vitamin D levels of 24 to 29 ng/mL. The authors stressed that this was the reason why spring flus in the late winter/early spring season are common, but disappear in summer.

Vitamin D requirements for immune system is 2000 IU or more per day

Vitamin D is essential for the functioning of the innate and adaptive immune system. They also are the reason why children are not as affected by influenza viruses as adults are. Dr. Cannell said: “The innate immunity of the aged declined over the last 20 years due to medical and governmental warnings to avoid the sun. While the young usually ignore such advice, the elderly often follow it”. Had the older patients taken higher doses of vitamin D3 every day, their immunity would have been as strong as the children’s immunity. The publication cites another paper that found that 2000 IU per day or more will strengthen the immune system. Note that this is a higher dose than  treating rickets. Treatment of rickets responds to only 400 IU of vitamin D3 per day.

Mechanism of action of vitamin D in infectious diseases like influenza or Covid-19 coronavirus

Here is evidence from US researchers that states that higher doses of vitamin D3 will mitigate the course of influenza and of Covid-19 coronavirus. The researchers outlined that vitamin D has 3 effects:

  1. Maintaining tight epithelial junctions making it more difficult for the Covid-19 coronavirus to penetrate them.
  2. “Killing enveloped viruses through induction of cathelicidin and defensins.” These powerful antiviral polypeptides can kill viruses that have invaded the bloodstream within 1 to 2 days.
  3. “…And reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia.” People who get viral pneumonia are at a high risk of death. By bringing the vitamin D blood level up to the higher range of normal, between 50 and 80 ng/mL, patients that have encountered Covid-19 coronavirus are more likely to survive.

Criticism of high dose vitamin D treatment

A common criticism of treatment with higher doses of vitamin D is that people would develop high blood calcium levels and would get kidney stones. Three recent studies have demystified this. A 2012 study looked at patients who were in the higher range of calcium levels, but deficient in vitamin D. They were treated with vitamin D3 und closely supervised. The calcium levels did not change after 1 year of high doses of vitamin D.

This 2018 study observed that there is a small amount of kidney stone formers who will form kidney stone with or without vitamin D3 treatment.  However, the large majority of patients do not form kidney stones with vitamin D treatment and their blood calcium levels stay the same before and after vitamin D treatment.

Toxic vitamin D blood levels

Toxic levels of vitamin D blood levels are above150 ng/mL, or 375 nmol/L. The therapeutic levels discussed here are well below these toxic levels.

Placebo controlled New Zealand study fails to show kidney stones

A placebo-controlled study from New Zealand went on for 3.3 years. 100,000 IU of vitamin D3 monthly (3333 IU per day on average) in the experimental group were compared to a placebo group. There were no vitamin D induced kidney stones and also no changes in calcium levels.

In past studies regarding vitamin D toxicity were done. But with these investigations there were many confounding factors that led to false results.  The investigators at those times mistakenly thought that they were side-effects of vitamin D. Up to this day conventional medicine often warns of hypercalcemia and kidney stones with vitamin D treatment. While the patient is on higher vitamin D levels, the physician can do blood and urine tests to see whether or not there is any concern.

Polypeptides released by vitamin D

There are more than 100 polypeptide hormones that are controlled by vitamin D. The most important ones for control of bacterial and viral infections are the defensin family and the cathelicidin family of polypeptides. They are instrumental in preventing the cytokine storm with a Covid-19 coronavirus infection treated with high vitamin D doses.

Decades after the original description of vitamin D researchers found out that vitamin D actually is a hormone.

There are vitamin D hormone receptors on almost every cell of the body. Vitamin D integrates the body cells and they respond as one unit. It is only recently that researchers found out about the release of polypeptides, particularly defensin and cathelicidin. They are  vital in the defence against the Covid-19 Coronavirus and the various flu types.

Vitamin D Is the Definitive Link

Vitamin D Is the Definitive Link

Conclusion

The detection of vitamin D originally occurred when rickets was examined. But later researchers found that vitamin D has hormone qualities.

You can prevent several diseases, like arthritis, cardiovascular disease, breast cancer, diabetes, osteoporosis and influenza. But you must take adequate amounts of vitamin D to bring the vitamin D blood level up. 25-hydroxy vitamin D blood levels are now recognized as the standard test to measure whether you have enough vitamin D on board. When it comes to fighting infections the vitamin D blood level has to be above 30 ng/mL (above 75 nmol/L). At this level the immune system will release defensin and cathelicidin polypeptides. These are powerful antiviral and antibacterial substances that can even fight Covid-19 coronavirus.

High vitamin D therapy is safe

With careful monitoring of blood vitamin D levels side effects of high vitamin D dosages were not found. Conventional medicine keeps on repeating old studies with confounding errors. This scares people, and as a result they don’t want to take enough vitamin D for prevention. Hypercalcemia and kidney stones were NOT found in randomized newer studies. As long as the vitamin D level does not exceed 50-80 ng/mL (or 125-200 nmol/L) vitamin D therapy is perfectly safe.

Our Immune System Needs Vitamin D3

When we age, our resistance to infections weakens, but this may be because our immune system needs more vitamin D3. I have reviewed the super powers of vitamin D3 before in 2014. In the past it was thought that the human body would need only 400 IU of vitamin D3 every day to cure rickets. And this was the daily recommendation for vitamin D3 for several decades. Gradually it became known that for cancer prevention, infection prevention, cardiovascular illness prevention and for diabetes prevention much higher doses of vitamin D3 were needed. As this link points out, almost 50% of the world population is deficient in vitamin D. This is due to a lack of exposure to sunlight and due to inadequate supplementation with vitamin D3.

25-hydroxy vitamin D level

For several years now the 25-hydroxy vitamin D level in serum is accepted as the best tool to assess the vitamin D status of a person.  In the following you find data from this link.

Various 25-hydroxy vitamin D levels

Vitamin D deficiency (leading to rickets in infants or osteomalacia in adults): less than 12 ng/mL (less than 30 nmol/L)

 Inadequate vitamin D levels in healthy individuals (inadequate for bone or general health): 12 ng/mL to less than 20 ng/mL (30 to less than 50 nmol/L)

 Considered adequate for bone and overall health: 20 or more ng/mL (50 or more nmol/L)

 “Emerging evidence links potential adverse effects to such high levels”: >50 ng/mL(particularly >60 ng/mL); or >125 (particularly >150 nmol/L)

Vitamin D requirement in diseases other than rickets

We see from this that in terms of rickets there is a clear dose-response curve, where low vitamin D serum levels give a child rickets and higher levels prevent rickets. This is historically how vitamin D was detected as a vitamin. In the meantime, researchers have found vitamin receptors on many cells, so that endocrinologists consider vitamin D3 a hormone and signalling molecule.

The above link said that a vitamin D level of 20 to 50 ng/mL is normal. This link says that 20 and 40 ng/mL would be normal. But it adds that others recommend a level between 30 and 50 ng/mL.

Mortality of ICU patients is higher when vitamin D is low

A study from 2015 examined the mortality of 135 ICU patients. The researchers correlated Vitamin D blood levels with mortality rates of the patients. When vitamin D levels were below 12 ng/mL, there was a mortality rate of 32.2%. Patients with higher levels of vitamin D had a mortality rate of 13.2%. The authors concluded that low vitamin D blood levels were an independent risk factor for mortality. Patients less than 12 ng/ml had a 2.4-fold higher risk of dying than patients with normal vitamin D levels.

Stroke patients with low vitamin D worse off

Studies have shown that patients with the lowest level of vitamin D have the poorest functional outcomes following a stroke. When the vitamin D level was below 30 ng/mL the area of dead brain tissue was about two times larger than in those who had adequate vitamin D levels. Moreover, for every 10 ng/mL decrease in vitamin D levels the odds of a healthy recovery 3 months after the stroke fell by about half. This was independent of age and the initial stroke severity.

Seasonal vitamin D3 deficiency from January through April contributes to influenza

In a publication of 2006 Dr. John Cannell and co-workers have reviewed why influenza has seasonal outbreaks. They found that the innate immune system was very dependent on vitamin D3. Those who did not get enough sunlight in the northern hemisphere during January, February, March and April have an average 25-hydroxy vitamin D level of only 15 to 17 ng/mL. In contrast, from July to September the same volunteers had vitamin D levels of 24 to 29 ng/mL. The authors stressed that this was the reason why in the late winter/early spring flu seasons come and go every year while in summer they disappear.

Vitamin D requirements for immune system is 2000 IU or more per day

Vitamin D is essential for the functioning of the innate and adaptive immune system. They also had a reason why children are not as affected by influenza viruses as adults are: “The innate immunity of the aged declined over the last 20 years due to medical and governmental warnings to avoid the sun. While the young usually ignore such advice, the elderly often follow it”. Had the older patients taken higher doses of vitamin D3 every day their immunity would have been as strong as the children’s immunity. The publication cites another publication that found that 2000 IU per day or more will strengthen the immune system. Note that this is a higher dose than for rickets that responds to only 400 IU of vitamin D3.

Patients with many diseases lack vitamin D, but improve with vitamin D3

Many diseases showed an association with an underlying lack of vitamin D. When doctors examine patients’ blood who have arthritis, cardiovascular disease, breast cancer, diabetes, osteoporosis, influenza and others, their 25-hydroxy vitamin D level is usually below 15 ng/mL. This means that these patients have a very weak immune system. Vitamin D3 can restore their immune system and also restore more than 100 polypeptides that contribute to the healing process.

Here is evidence from US researchers that states that higher doses of vitamin D3 will mitigate the course of influenza and of Covid-19 coronavirus. The researchers outlined vitamin D has 3 effects:

  1. Maintaining tight epithelial junctions making it more difficult for the Covid-19 coronavirus to penetrate.
  2. “Killing enveloped viruses through induction of cathelicidin and defensins.” These powerful antiviral polypeptides can kill viruses that have invaded the blood stream within 1 to 2 days.
  3. “…And reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia.” It is people who get the viral pneumonia that are at a high risk of being killed. By bringing the blood level up to the higher range of normal, between 50 and 80 ng/mL, patients that have encountered Covid-19 coronavirus are more likely to survive.

Higher doses of vitamin D3 for various diseases

Dr. Norman Shealy has summarized here what Dr. Joe Prendergast, an endocrinologist and diabetologist did for various patients. This link also contains many references regarding the use of high doses of vitamin D3.

During 30 years of clinical practice Dr. Prendergast treated some conditions where the vitamin D level was extremely low and where patients had a profound weakness of the immune system.

He treated these patients with 50,000 IU of vitamin D3 daily for various times. The diseases that responded to vitamin D3 therapy follow.

Conditions responding to vitamin D3 therapy

  • Reversal of advanced coronary disease
  • Reversal of advanced lung disease, avoiding a lung transplant!
  • Cure of multiple sclerosis
  • Cure of amyotrophic lateral sclerosis
  • Regression of rheumatoid arthritis
  • Improvement in allergies
  • Control of many cancers including prostate, breast, colon, brain tumors, leukemia, myeloma, etc.
  • Reversal of osteoporosis
  • Prevention of influenza
  • Cure of depression and many other mental disorders
  • Hashimoto’s hyperthyroidism

No toxicity with higher doses of vitamin D3

LinkedIn summarizes Dr. Prendergast’s career as follows:

“J. Joseph Prendergast has been a practicing physician for over 30 years. He is Board Certified in Internal Medicine as well as Endocrinology and Metabolism. A graduate of Wayne State University in Detroit, Michigan he completed a fellowship in Endocrinology and Metabolism at Henry Ford Hospital Detroit, MI and his residency at the University of California, San Francisco. Dr. Prendergast has published over 40 medical articles in well-known publications such as the Journal of the American Medical Association, The New England Journal of Medicine and Diabetes Care.”

Do not take calcium supplements when on higher doses of vitamin D3

Dr. Prendergast had no complications in patients with these high doses of vitamin D3, but he stressed that the patient is instructed not to take calcium supplements to prevent high calcium levels. He checks vitamin D blood levels and aims at levels of 80 to 150 ng/mL.

The dosage suggested on this audiotape is 50,000 IU per day for one week, then a maintenance dose of 50,000 IU once per week (=7143 IU per day). But it is also important to change your nutrition to a well-balanced diet. He stated that there is no toxicity with this treatment schedule as long as you do not take additional calcium supplements. On the other hand, dairy products are OK to take.

Our Immune System Needs Vitamin D3

Our Immune System Needs Vitamin D3

Conclusion

Many patients with diseases like osteoporosis, high blood pressure, cardiovascular disease, influenza, multiple sclerosis, allergies and other disease listed above have very low vitamin D blood levels. Vitamin D is necessary to produce more than 100 polypeptides. The body requires these for normal cell function. Rickets was first cured by supplements of only 400 IU of vitamin D3 per day. In the meantime, it is recognized that a vitamin D level of less than 15 ng/mL constitutes a vitamin D deficiency. To cure other diseases requires much higher vitamin D levels in the blood, in the order of 50 to 80 ng/mL.

Dr. Prendergast uses higher vitamin D levels with better results

Dr. Prendergast states that patients with pre-existing diseases have to take much higher levels of vitamin D3. This rebalances their metabolism and cell function. In time this will gradually cure their disease. He suggests 50,000 IU of vitamin D3 daily for 7 days. This is then followed by 50,000 IU per week (7143 IU per day) for maintenance. He said that this will lead to a vitamin D level of between 80 and 150 ng/mL. In 30 years of practice he has not seen a single case of vitamin D3 toxicity, provided the patient refrains from taking calcium supplements. This is the exact opposite of what the Mayo Clinic or Harvard University websites say. It also shows that there are always some pioneering forces in the generally ultra-conservative medical society.

Fight The Cold Or Flu With Mega Vitamin D3 Doses

Recently I came down with a cold, when I remembered that you can fight the cold or flu with mega vitamin D3 doses. The cold did not fit into my plans. I was three days before singing as a lead singer in a local church and I needed my voice. I felt a burning in the back of my throat and knew I was coming down with a cold. Next I felt congested in my nose and sinuses. I braced myself for the cold affecting my voice box and taking my voice away. But on the second day of the cold/flu I took 50,000 IU of vitamin D3. The following day the congestion was still confined to my nose and sinuses only. But it did not go any further down into my throat or chest.

Mega vitamin D3 doses saved my voice 

The following day was the church performance and everything went well. The Christmas songs created a festive atmosphere in the congregation. The psalm melody that my wife had composed was a welcome change from the normally stuffy psalm. And despite the feeling of an oncoming cold, my voice was still clear.

My cold did not progress

Since then I noticed some more mucous formation and I continued my dose of 50,000 vitamin D3 for a total of 3 doses. Through blood tests for vitamin D 3 levels I know that I am a slow absorber of vitamin D3 and normally need 10,000 IU daily to get into the normal range of 25-hydroxy vitamin D using a blood test. Now the cold symptoms settled down. There was nothing of the common laryngitis, where you sound scratchy. I also did not get a cough, which based on past experience, would have lingered on for weeks.

How vitamin D stimulates the immune system

Taking high doses of vitamin D3 releases cathelicidin and defensins.

These are polypeptides that have antibacterial and antiviral properties. The vitamin D antimicrobial pathway is described in detail here:

Vitamin D stimulates the immune system (B cells and T cells), which can suppress viral and bacterial infections. Here is another article that recommends the “vitamin D hammer” as the authors term the mega vitamin D3 therapy. Dr. Thornburg describes that an adult should treat a cold/flu within 24 to 36 hours after onset with 50,000 IU of vitamin D3 once daily for 3 days. He also lists pediatric doses. Following this treatment the patient resumes the previous vitamin D3 maintenance dose.

Opinion of conventional medicine

This approach is not conventional medicine. Here is a publication that states that Vitamin D, Vitamin C, Zinc, and Echinacea in combination can be useful in the treatment of the common cold.

But the section that describes the use of vitamin D seems to be very conservative. It does not even mention the importance of measuring the vitamin D blood levels. It is 25-hydroxy vitamin D which is what one needs to determine blood levels.

The normal level is considered to be 25-80 ng/mL. Many physicians say a level of 50-80 ng/mL is better. This blood test will measure the sum of vitamin D from oral vitamin D3 and from sun-induced vitamin D. This test also shows whether a person is a fast absorber or a slow absorber. What counts is that a person taking vitamin D3 gets the blood level into the therapeutic range.

Are there toxic levels of vitamin D?

Whenever the topic of mega dose vitamin D3 is mentioned, conventional medicine will warn that vitamin D toxicity could develop including kidney stones and “bone pain, drowsiness, continuous headaches, irregular heartbeat, loss of appetite, muscle and joint pain”.

In these cases of toxicity the researchers did not indicate what the level of 25-hydroxy vitamin D level was.

Other publications have established that the original recommended dose of vitamin D3 by the Food and Nutrition Board of 2000 IU per day was way too low. According to this publication based on many other papers 10,000 IU per day or more should be considered the new recommendation.

Dr. Schwalfenberg stated: “This is a 1-time 50, 000 IU dose of vitamin D3 or 10, 000 IU 3 times daily for 2 to 3 days. The results are dramatic, with complete resolution of symptoms in 48 to 72 hours. One-time doses of vitamin D at this level have been used safely and have never been shown to be toxic.”

The half-life of 25-hydroxy-vitamin D3 is 15.1 days. This means that the transient elevation of 25-hydroxy-vitamin D3 will last only 5 half-lives or 75.5 days. After that time (2 1/2 months) the mega dose taken over 3 days is eliminated.

Fight The Cold Or Flu With Mega Vitamin D3 Doses

Fight The Cold Or Flu With Mega Vitamin D3 Doses

Conclusion

Vitamin D3 has long recognition as a stimulant of the immune system. We now know that high doses of vitamin D3 release two polypeptides, cathelicidin and defensins. They have antibacterial and antiviral actions. Several physicians have developed a mega vitamin D3 approach when a cold or flu just starts to hit you. An adult should then take 50,000 IU of vitamin D3 daily for 3 days. In many cases it will cut the cold/flu short within 48 to 72 hours. Dr. Schwalfenberg said that “one-time doses of vitamin D at this level have been used safely and have never been shown to be toxic.”

Possible future clinical trial could verify effectiveness of mega vitamin D3

It would be desirable that the medical establishment conduct a clinical trial about the effectiveness of mega vitamin D3 use in colds/flus. Once the results are out, it would be loss of business for the pharmaceutical manufacturers.  Most of the cold-remedies would no longer be in high demand. For this reason it does not appear that it would be in the interest of Big Pharma or of organized medicine to organize such a clinical trial!

Take Enough Vitamin D3

Many people supplement with 300 to 400 IU of vitamin D3, but do they take enough vitamin D3? There is a simple way of finding out: ask your doctor to order a 25-hydroxyvitamin D blood test.   This will show whether the gut absorbed enough of the essential vitamin. It will also show whether or not your vitamin D3 capsules or tablets were strong enough. It is now generally accepted that a good range of the vitamin D blood level is between 50 and 80 ng/ml. Unfortunately many Americans who come down with various diseases have blood levels of less than 30 ng/ml. Here are some facts about what a lack of vitamin D3 can cause.

Increased risk of mortality with lower vitamin D levels in ICU patients

  1. A New England Journal study from 2009 reported about 1100 patients in Intensive Care Units (ICU). Their average vitamin D blood level was only 16 ng/ml. They tracked the mortality rates depending on the vitamin D blood level. Insufficient vitamin D levels showed an association with a mortality rate of 45%. An intermediate level had a mortality rate of 35%. And a satisfactory level of vitamin D had a mortality of only16%. Between the low level of vitamin D and the normal level there was a 3-fold difference in mortality!
  2. Another study from 2015 repeated the mortality study with 135 ICU patients. Researchers correlated Vitamin D blood levels with mortality rates of patients. When vitamin D levels were below 12 ng/ml, there was a mortality rate of 32.2%. Patients with higher levels of vitamin D had a mortality rate of 13.2%. The authors concluded that vitamin D blood levels were an independent risk factor for mortality. Patients less than 12 ng/ml had a 2.4-fold higher risk of dying than patients with normal vitamin D levels.

Do patients with multiple sclerosis take enough vitamin D3?

Perhaps one of the earliest results of vitamin D3 research was the following observation. More than 90% of patients with multiple sclerosis were deficient in vitamin D blood levels. Their levels were below 20 ng/ml. Other researchers showed that vitamin D could directly tone down the aggressiveness of the immune cells of MS patients. These were the ones that attacked the myelin sheath. As a result of this knowledge it is important for MS patients to take high enough vitamin D3 supplements. When they reach good vitamin D blood levels their MS is better controlled.

Canada as a northern country has 291 MS patients per 100,000 people. Contrast this to 110-140 MS patients per 100,000 people in the northern US (between the 37th parallel and the US/Canadian border). In addition south of the 37th parallel there are only 57-78 cases of MS per 100,000 people. Researchers have concluded that the less sun light people get, the higher the rate of MS in the population will be. However, instead of sun exposure you can supplement with vitamin D3 capsules to get the blood vitamin D levels up to the range of between 50 and 80 ng/ml.

Do stroke patients take enough vitamin D3?

Strokes are very common. About 6.8 million Americans survive a stroke and live with various disabilities. 15% die shortly after their stroke. 40% are left with moderate to severe disabilities. Many require special care.

  1. Studies have shown that patients with the lowest level of vitamin D have the poorest functional outcomes. Moreover, for every 10 ng/ml decrease in vitamin D levels the odds of a healthy recovery 3 months after the stroke fell by about half. This was independent of age and the initial stroke severity.
  2. In another 2015 study from South Korea 818 stroke patients took tests to evaluate whether they had adequate vitamin D blood levels. There was a clear division between those whose levels were higher than 10 ng/ml or lower. When the vitamin D level was higher, there was a 90% better recovery from their stroke after 3 months. In comparison those whose vitamin D levels were below 10 ng/ml had poor recovery rates. Experts say that vitamin D levels should stay in the range between 50 and 80 ng/ml. This will prevent numerous diseases.

Do diabetics take enough vitamin D3?

  1. Vitamin D3 can silence diabetes genes in connection with the right diet and cofactors of zinc and magnesium. A Mediterranean diet can stabilize the metabolism and fight inflammation. Zinc and magnesium are important cofactors in enzymes necessary to prevent diabetes. Vitamin D3 and omega-3intake are helping to control inflammation and preserve beta cells in the pancreas in diabetes patients. This is important for continued production of insulin.
  2. A Chinese research team found that vitamin D3 protects beta cells in the pancreas from dying off. The finding was that vitamin D3 receptors in the insulin producing cells prevented the dying off of these cells, as long as there was enough vitamin D available. Insulin production by the pancreas remained effective. And insulin is vital for long-term survival of diabetes patients. The key for diabetes patients is to take adequate doses of vitamin D3 to protect their insulin producing beta cells.
  3. A 2015 Italian study showed that micro vascular complications in diabetes patients were high, if the vitamin D3 blood levels were low. If patients had high levels of vitamin D3, there were no complications such as retinopathy or nephropathy. But if levels were below 20 ng/ml, damages were significant in the capillaries of the eyes and kidneys.

Do patients with inflammatory conditions take enough vitamin D3?

What do the lining of the arteries, the inflamed joints, a degenerative meniscus and heart attacks and strokes have in common? It is the inflammation that changes the body chemistry. It gets even more complicated, because the extra calories that we consume get stored as visceral fat. This is done automatically when you eat too much sugar and starchy foods. When the glycogen stores are full, any surplus sugar gets metabolized by the liver into triglycerides, fatty acids and LDL cholesterol and gets stored as body fat. The most active fat is the visceral fat between our guts and around our body organs. This produces interleukins and other inflammatory cytokines that circulate in the blood causing inflammation in all our arteries. Interleukin-6 is an inflammatory cytokine. High interleukin-6 levels contribute to causation of various cancers.

This 2015 study from Seattle University followed 218 obese postmenopausal women with a body mass index of larger than 25.0 for 12 months. Both received weight loss intervention and either 2000 IU of vitamin D3 daily or a placebo pill. Both groups lost about 5 to 10% of weight in 12 months. However, the interleukin-6 level of the vitamin D3 group had a reduction of 37.3%. This was in stark contrast to the placebo group where the interleukin-6 level reduction was only 17.2%. This type of research shows the incredible power of vitamin D3. This likely is the reason why several cancer frequencies can show a reduction with regular vitamin D3 supplementation.

Attention deficit disorder and vitamin D3

  1. Other research compared a group of 37 children with attention deficit hyperactivity disorder (ADHD to 37 normal children. Blood levels of vitamin D were 19.11±10.10 ng/ml in the ADHD group and 28.67±13.76 ng/ml in the normal group. Other researchers have found similar findings, establishing that very low vitamin D levels have a connection with ADHD.
  2. A prospective study from Spain involving 1,650 mother-child pairs investigated the effect of mother’s vitamin D level during her pregnancy with the risk for ADHD by the time the child was 4 to 5 years old. Schoolteachers followed the standard test procedures to establish the ADHD diagnosis. The study showed that for every 10-ng/ml increment of the mother’s blood vitamin D level during her pregnancy the children had 11% less ADHD-like symptoms. The authors cautioned that it takes mega doses of vitamin D3 to reach these kinds of results. The usual 400 IU of vitamin D3 per day will not achieve the desired increase of vitamin D3 levels, but amounts of 5,000 IU to 8,000 IU are necessary to achieve this.

Schizophrenia and vitamin D3

A 2014 Meta analysis found that low vitamin D levels have an association with a 2.16-times higher probability of having schizophrenia than controls with normal vitamin D levels. Another study examined whether those patients who had an acute psychosis would have lower vitamin D blood levels than schizophrenia patients in remission or control patients without schizophrenia. Studies compared 40 patients with an acute psychosis to 41 patients in remission and 40 healthy controls. Patients with an acute psychosis had extremely low vitamin D blood levels, while patients in remission had much better vitamin D levels. Healthy controls had the best vitamin D levels.

Absorption and metabolism of vitamin D3

Magnesium plays a central role in activating vitamin D3. This publication points out that magnesium is also necessary for absorption of vitamin D3 in the gut. The activation of vitamin D3 is also partially responsible for vitamin D absorption. Both vitamin D3 and magnesium play an important role in bone and calcium metabolism. The fact that every body cell has vitamin D3 receptors shows how important it is for the maintenance of the body. Many researchers say that vitamin D3 qualifies as a hormone because of the specific effects on cells via vitamin D3 receptors.

Take Enough Vitamin D3

Take Enough Vitamin D3

Conclusion

Vitamin D3 is an important signaling hormone and vitamin that regulates the body’s calcium absorption and is responsible for bone metabolism. Research has shown that the lack of vitamin D3 causes several unrelated diseases, like rickets, multiple sclerosis, and schizophrenia. But other diseases, where a lack of vitamin D3 was present, were diabetes, attention deficit disorder and strokes. When patients with elevated inflammatory markers take vitamin D3 their interleukin-6 levels dropped by 37.3%. To achieve this, patients needed to consume at least 2000 IU. We all should have our vitamin D blood level measured from time to time. It should be between 50 and 80 ng/ml. Too many Americans are deficient in vitamin D3 and come down with the diseases mentioned! Prevention and supplementation go hand in hand. You can prevent a lot of diseases this way.

Vitamin D3 Protects Your Brain

More and more studies are showing that vitamin D3 protects your brain. It protects against MS, but also against Parkinson’s disease and Alzheimer’s disease. In the following I will review what evidence there is to support each of these topics.

Vitamin D3 protects your brain from multiple sclerosis (MS)

It has been known for some time that in the northern hemisphere MS is more common because of the lack of sunshine, which in turn produces less vitamin D3 in the skin.

MS is an autoimmune disease where immune cells attack the lining of nerves. Both nerve cells and immune cells have vitamin D receptors. It appears that immune cells are calmed down by vitamin D3 and remission of an MS relapse is more likely.

There are two forms of MS, the relapsing-remitting MS and the progressive MS. The first one (relapsing-remitting) is more common. After a bout of active MS, the illness calms down and the condition of the patient is stable for some time until the next relapse occurs.

With progressive MS there are two forms, primary progressive MS and secondary progressive MS. The primary form is a case of MS where symptoms steadily worsen, without any remission. The secondary form of progressive MS occurs at the end of fairly stable relapsing-remitting MS. Symptoms become more pronounced and the condition deteriorates steadily from there.

Progression and disability in MS patients with various vitamin D3 levels

Dr. Fitzgerald and colleagues published a study in JAMA Neurology in 2015.

They took 1482 men and women who were on interferon beta-1b treatment. This treatment utilizes the immunomodulator interferon beta-1b and reduces the number of relapses in patients with MS. The study took place between November 2003 and June 2005. Results were analyzed between June 2013 and December 2014. The researchers measured vitamin D levels (as 25-hydroxy vitamin D). The vitamin D levels were obtained at baseline, at 6 months and 12 months.

The number of brain lesions were measured by MRI scans. All of the patients also underwent a functional test, called expanded disability status scale. This measured impairment of ambulation, ability to communicate and activity levels.

Results of this study showed marked differences between patients with high and low vitamin D levels. Those patients who had the highest vitamin D blood levels (more than 40 ng/mL) had the lowest rates of new MS lesions. Previous studies had found that a low blood level of vitamin D (less than 25 ng/mL) in patients was associated with a much higher risk of developing MS. Dr. Fitzgerald’s study showed that a 50.0-nmol/L increase in serum vitamin D levels associated with a 31% lower rate of new MS lesions. Patients with the highest vitamin D level of more than 100 nmol/L had the lowest amount of new MRI lesions (47% less than the patients with the lowest vitamin D levels).

Another study showed that a low-dose vitamin D level accelerated MS. There was a 5.9-fold risk converting the initial relapsing-remitting form of MS into the secondary progressive form of MS.

All these studies show that vitamin D3 can decrease the risk of getting MS. In addition vitamin D3 also delays progression in those who have MS.

Vitamin D3 protects your brain from Parkinson’s disease

Vitamin D3 plays a role in preventing Parkinson’s disease.

Parkinson’s disease is a neurodegenerative disease that causes tremor in muscles, causes balancing problems and eventually can lead to dementia. A metaanalysis was done in 2014 and 7 studies where identified to be relevant. The authors were looking for correlation of vitamin D levels with Parkinson’s disease. The study included 1008 patients in the metaanalysis with 4,536 controls.

  • Patients with a vitamin D level of less than 75 nmol/L had a 1.5-fold higher risk of developing Parkinson’s disease than the controls.
  • Patients with a vitamin D level of less than 50 nmol/L were at a 2.2-fold higher risk of developing Parkinson’s disease.

Another metaanalysis utilized 5,690 Parkinson’s disease patients and 21251 matched controls.

It found that vitamin D levels of less than 20 ng/ml were associated with a risk of 2.08-fold to develop Parkinson’s disease. Interestingly, vitamin D3 supplementation reduced the risk of Parkinson’s disease by 38%. Outdoor work reduced the risk of developing Parkinson’s disease by 28%.

Vitamin D3 protects your brain from Alzheimer’s disease

Alzheimer’s disease is a neurodegenerative disease of old age. We know that it is much more common in patients with type 2 diabetes where insulin levels are high. Studies have shown that Alzheimer’s disease can be termed type 3 diabetes.

The resulting neurofibrillary tangles and amyloid-beta deposits damage nerve cells, which are responsible for the memory loss and the profound personality changes in these patients.

What does vitamin D3 have to do with this?

A 2014 study showed that a low vitamin D level was associated with a high risk of dementia and Alzheimer’s disease.

Specifically, the researchers found the following observations.

  • Vitamin D level of less than 10 ng/ml: 122% increased risk of Alzheimer’s
  • Vitamin D level 10 to 20 ng/ml: 51% increased risk of Alzheimer’s

The same research group found in two trials that vitamin D deficiency leads to visual memory decline, but not to verbal memory decline.

Vitamin D3 combined with metformin suppresses cancer

The newest development with respect to vitamin D3 is the finding that it also has anti-cancer effects. Dr. Li demonstrated that vitamin D reduced prostate cancer cell line growth by 45% while metformin alone reduced it by 28%.

But when both vitamin D and metformin were present in the cell cultures there was growth inhibition of 86%. Dr. Li explained that vitamin D potentiated the growth inhibitory effect of metformin.

Vitamin D3 protects your brain: guidelines to proper vitamin D3 dosing

For years the medical profession stated that 400 IU of vitamin D3 would be enough supplementation. It may be enough to prevent rickets in children. But these low doses will be insufficient in many patients who are deficient for vitamin D to prevent MS, Parkinson’s disease, Alzheimer’s disease or cancer.

A study on medical staff in Northern India showed that 85% of the staff had very low vitamin D levels of less than 10 ng/ml.

It took high doses of vitamin D3 to increase the vitamin D level in the blood.

Generally supplements of vitamin D3 of 5000 IU to 8000 IU are the norm now. But some patients are poor absorbers and they may require 15,000 IU per day. The doctor can determine the patient’s requirement for vitamin D by doing repeat vitamin D blood levels (as 25-hydroxy vitamin D). The goal is to reach a level of 50-80 ng/ml. The optimal level with regard to nmol/L is 80 to 200 (according to Rocky Mountain Analytical, Calgary, AB, Canada).

Vitamin D3 Protects Your Brain

Vitamin D3 Protects Your Brain

Conclusion

Many people are deficient with regard to vitamin D, and they do not know it. The most important thing is to do a vitamin D blood test to assess your vitamin D status.

We know for a long time that vitamin D plays a role in bone metabolism and this is why women approaching menopause often need vitamin D3 supplementation. But it may come to you as news that vitamin D3 also protects from MS, Parkinson’s disease and Alzheimer’s disease. In addition, as indicated above, we know that vitamin D3 when taken regularly suppresses many cancers.

When you realize that all body cells have vitamin D receptors on their surface, it is no surprise that vitamin D3 is so important to take. The vitamin D3 receptors must be there for a reason. When you deprive your body of this valuable vitamin, the high risk of degenerative diseases will be the consequence.

High Vitamin D3 Prevents Cancer

In the last few years we learnt a lot about vitamin D3, but the newest thing is that high vitamin D3 prevents cancer.

Researchers at the University of California, San Diego School of Medicine reported that with respect to several cancer types higher doses of vitamin D3 led to less cancer over a period of time.

The cancers investigated were colon cancer, breast cancer, and lung and bladder cancer. People absorb vitamin D3 differently.  The researchers found that the best way to measure vitamin D3 concentration in the body is to use serum 25-hydroxyvitamin D (25(OH)D). In the past people did not pay much attention to this matter. However, several studies including the present study showed that in patients who had a lower level of 20 ng/ml cancer rates were higher.

Comparison of two cohort studies

The researchers used data from two prior studies, a randomized clinical trial of 1,169 women and a prospective cohort study of 1,135 women. The researchers found that the age-adjusted cancer incidence was 1,020 cases per 100,000 person-years in the randomized clinical trial, called “Lappe cohort”. The other prospective cohort study was called the “GrassrootsHealth cohort” where cancer incidence was 722 per 100,000 person-years. The interesting fact was that the Lappe cohort median blood serum level of 25(OH)D was 30 nanograms per milliliter, while the GrassrootsHealth cohort had a higher level of 25(OH)D of 48 ng/ml.

Higher vitamin D levels correlate with lower cancer incidence

This likely explains the lower cancer rate in the GrassrootsHealth cohort. Researchers combined the two trials in order to increase the statistical significance . The striking finding was that above 40 ng/ml the overall cancer risk was more than 71% lower than for the group of people whose level of 25(OH)D was 20 ng/ml or lower. The above ScienceDaily article was based on this scientific study.

Other studies showing high vitamin D3 prevents cancer

AfroAmerican men had less prostate cancer, if vitamin D level was higher

In a 2015 study Afro American men were found to have 71% less prostate cancer, if their serum 25-hydroxyvitamin D level was at least 30 ng/ml or higher.

Prospective study showing high vitamin D levels cancer protective

This 2006 study reported a 14-year prospective follow-up in men where all cancers were counted and blood serum 25-hydroxyvitamin D levels were correlated to cancer incidence. An increase of 25 nmol/L (=10 ng/ml) in predicted serum 25(OH)D level showed an association of a 17% reduction in total cancer incidence, with a 29% reduction in total cancer mortality and a 45% reduction in digestive-system cancer mortality. These investigators stated that it takes about 1500 IU of vitamin D3 increase per day to achieve an increment of serum 25(OH)D increment of 25 nmol/L (=10 ng/ml).

University of Arizona Cancer Center study

A publication from the University of Arizona Cancer Center in Jan. 2016 is more critical of the evidence regarding vitamin D3 and the claim that it lowers cancer rates. The researchers reviewed the cancer literature and found that for colorectal cancer there is a clear inverse relationship between serum 25(OH)D levels on the one hand and rates and mortality of colorectal cancer on the other hand. However, with breast cancer the literature was more divided. Only higher vitamin D levels were related to a lower risk for progression of breast cancer and a lower mortality rate. Randomized, double-blind clinical trials with regard to breast cancer failed to show effectiveness on cancer prevention or reduction of mortality. For prostate cancer conditions were similar with the exception of a study using 4000 IU of vitamin D3 per day, which inhibited progression of prostate cancer.

Mouse model regarding ovarian cancer and vitamin D

In a mouse model using a carcinogen to induce ovarian cancer there was an inverse dose-relationship between vitamin D3 and ovarian tumor development both in tissue culture and in the animal.

How high vitamin D3 prevents cancer

Immune stimulating effect of vitamin D3

Several studies have attempted to speculate how vitamin D3 may prevent cancer. Chirumbolo summarized the literature and noted that vitamin D3 has been shown to function as an immune cytokine stimulating the immune system non-specifically.  Vitamin D3 is also anti-inflammatory and counters insulin resistance and inflammatory kinins in obesity. Flavonoids with their antioxidant activity are also cancer preventing. We know that low levels of vitamin D have an association with higher cancer frequency. This means,. it is important to use vitamin D3 as supplements in our diet.

Chinese study describing action of vitamin D3 in detail

This Chinese study examined the effects of vitamin D3 on cancer prevention. It found that vitamin D3 combines three specific actions in one. Vitamin D3 is anti-proliferative meaning that it stops uncontrolled cell division. Secondly, it has an apoptotic (cell death) effect, which means it supports the removal of cells that are dying. If they are dying, but not removed, cancer can occur from these cell remnants. The third effect of vitamin D3 is that it has differentiating effects in several malignant cell types. When cancer cells are non-differentiated (=more immature cells) cancer can multiply quickly. Mature cells find it more difficult to turn cancerous. This is an effect that controls the speed by which cancer cells divide and how quickly cancer metastasizes.

High Vitamin D3 Prevents Cancer

High Vitamin D3 Prevents Cancer

Conclusion

There still is some confusion about the effects of vitamin D3 regarding cancer prevention. In colorectal cancer the statistics are clear: vitamin D3 can significantly prevent colorectal cancer to a large extent. There are also preventative effects in breast cancer and prostate cancer. But individuals may have to take at least 4000 IU of vitamin D3 or more. This is particularly true in higher latitudes where sunlight exposure is lower in the wintertime. Also, people absorb vitamin D3 differently. For this reason it is important to at least check your serum 25-hydroxyvitamin D levels on a few occasions. This will tell you whether your vitamin D3 supplementation is sufficient. Aim for levels in the 50-80 ng/ml, which is health promoting.

Apart from cancer prevention vitamin D3 is also important for prevention of cardiovascular disease. This is particularly true for diabetes, osteoporosis and Alzheimer’s disease.

The Super Powers Of Vitamin D

Originally, when vitamin D was found to be the missing ingredient in preventing rickets in growing children the recommended daily allowance (RDA) to prevent rickets was found to be 400 IU of vitamin D. The active metabolite has been identified as vitamin D3 for which the body has receptors on all vital organs (heart, brain, bones, kidneys, liver). In recent years new insights have been gained as it turns out that the RDA’s were set much too low for many diseases that can develop when vitamin D intake is too low, particularly in the aging population. Higher doses of vitamin D3 in the range of 800 to 1000 IU per day have been shown to prevent osteoporosis, falls and fractures in older adults and in nursing home populations. But the immune system of everybody is dependent on higher doses of vitamin D3. Recently (Dec. 12 to 15, 2013) I attended a lecture at the A4M conference in Las Vegas where Dr. Eisenstein reviewed the latest on vitamin D3. It is now known that 2/3 of the US population is deficient for vitamin D as measured by blood tests (less than 25 ng/ml).  The standard test is the 25-hydroxy-vitamin D level (abbreviated as 25(OH)D level). It is now known that you require at least a level of more than 40 to 60 ng/ml of 25(OH)D as measured in the US, which translates to more than 100 to 150 nmol/L measured in metric units in other countries, to prevent cancer.

The Super Powers Of Vitamin D

The Super Powers Of Vitamin D

Metabolism of vitamin D3

90% of the vitamin D3 that we need comes from exposure to sunlight, which transforms a cholesterol metabolite (7-dehydrocholesterol) into the vitamin D precursor (vitamin D3 or cholecalciferol). This is what we absorb from naturally occurring fish oil and oily fish, but otherwise this does not naturally occur in foodstuffs (Ref. 1). Dr. Eisenstein pointed out that it is well known that people living north of the 37th degree latitude lack vitamin D3 because of a lack of sun exposure, particularly in the winter season. People south of the 37th degree latitude have enough sun exposure, but wherever you live, it is advisable to have your vitamin D3 level measured (as 25(OH)D level). If you do not eat enough fish or fish oil, the levels likely are too low as is the case for 2/3 of the US population. Vitamin D3 supplements will have to be taken by those whose levels are too low. Vitamin D3 is further metabolized by the liver and then by the kidneys into the active vitamin D compound, called 1,25(OH)2D3 (which is called “calcitriol”). The main effect of calcitriol is to absorb calcium and phosphate from the intestine into the blood stream. Together with vitamin K2 as explained in a prior blog these minerals are then taken up by the bone to prevent osteoporosis or rickets in the growing child. What has not been known for a long time is that vitamin D3 is also necessary for normal cell metabolism by most of your body cells, but particularly by the vital organs like the brain, the heart, the kidneys, the liver, the immune system and the bone. However, doses of 5000 IU to 10,000 IU of vitamin D3 capsules per day are required for optimal vitamin D3 health. This will lead to levels of below 200 ng/ml of 25(OH)D levels, which have been proven to be safe. According to Dr. Eisenstein no toxicity has been found below 30,000 IU of vitamin D3 per day, but based on other authors a dose of 10,000IU should be adequate for most people. Strangely enough colored people also have to take vitamin D3 supplements as their the higher melanin pigment in the skin filters out UV light so effectively that their 25(OH)D level can be low. Always err on the cautious side and have your vitamin D3 blood level taken.

Vitamin D3 has a characteristic stereotactic configuration (cis-triene structure), which allows it to bind free radicals and function as an antioxidant (Ref.2).

What are some of the clinical effects of vitamin D3?

1. Vitamin D3 has diverse effects on organs systems as Dr. Eisenstein summarized: vitamin D3 lifts depression and has been found to be of particular value for drug resistant depression. Take 5000 to 10,000 IU of vitamin D3 per day.

2. Muscle power increases with vitamin D3, particularly in those who work out regularly.

3. Many fertility clinics pay attention to vitamin D3 levels, as the higher the blood levels of vitamin D3 in a man, the faster this sperms move! And the more vitamin D3 she has on board, the better she ovulates. The end result is a higher pregnancy success rate when both partners take 5000 to 10,000 IU of vitamin D3 per day

4. Also, if a woman takes vitamin D3 during her pregnancy, the first set of teeth in the offspring will have fewer cavities.

5. Brain development in autistic children is much improved with vitamin D3 in higher doses. This needs to be combined with detoxification methods and supervised by one of the DAN physicians.

6.Chronic pain typically improves when vitamin D3 deficiency, which almost always is present in patients with chronic pain, is treated with vitamin D3 supplementation.

7. To prevent flus and colds and other infectious diseases, take higher doses of vitamin D3. When you come down with a flu, it is safe to increase your daily vitamin D3 intake to 30,000 IU of vitamin D3 for a few days until your symptoms improve, then resume your maintenance dose of 5000 IU to 10,000 IU per day.  This year’s dominant flu is the type A, subtype H1N1 – also known as the swine flu. Children should get 50% of the dose regimen detailed for adults when they develop a flu (for children: 15,000IU for three to five days , with tapering to a maintenance dose of 2500 to 5000 IU until blood levels of 25(OH)D are available). Here is a website of Dr. Cannell where he discusses dosages as well.

8. Asthmatic patients do better with vitamin D3 supplements requiring less maintenance anti-asthmatic medicine to keep them balanced with regard to their airways.

9. Chronic low vitamin D3 levels cause brain damage including Alzheimer’s disease. In this context it is important to know that the enzymatic conversion in the liver and kidneys slow down as we age requiring higher doses in older patients. This may have been the reason for the confusion about relatively low doses of 400 IU of vitamin D3 preventing rickets in children versus the need of vitamin D3 in middle aged and older patients where much higher doses are required as already explained.

10. High blood pressure is linked to vitamin D3 deficiency and it is better manageable with medication when vitamin D3 levels are normalized.

11. Live longer with vitamin D3. How is this possible, you might ask: the answer has been found in the telomeres, the shoelace like structures at the end of the DNA strand of each cell. Vitamin D3 lengthens the telomeres and promotes telomere repair; this is associated with a longer life span. Centenarians have longer telomeres. You can measure telomere length, but it is a pricey test, which is not for everyone, contrary to supplementation with vitamin D3 that should be taken by everyone!

12. As already indicated, vitamin D3 strengthens the immune system, but it also modulates the inflammatory response from muscle damage, so athletes can perform better. Patients with multiple sclerosis will improve as it slows down the inflammatory process. But other inflammatory diseases like arthritis, inflammatory bowel disease and even cancer will respond favorably to higher doses of vitamin D3 (20,000 to 30,000 IU of vitamin D3 in these cases). This is information that has not yet percolated into mainstream medicine, but will do so in the next few years (or decades?).

13. Higher percentages of cardiovascular disease are found in patients who have lower than 15 ng/ml  25-Hydroxy- vitamin D3 levels in their blood meaning that vitamin D3 supplementation prevents heart disease (Ref.3).

What are toxic vitamin D levels?

What is known about the safety of vitamin D3, particularly the higher vitamin D3 doses? First, it is wise to have your 25(OH)D blood levels taken from time to time. If any of these levels exceed 200 ng/ml it would be prudent to reduce the vitamin D dose or stop supplementation for a while. Otherwise it has been difficult to establish a toxic range.

This website claims that 40,000 IU of vitamin D3 or more would lead to toxic levels where the blood calcium levels would be increased, which can be measured as hypercalcemia. However, another study done in 2007 showed in MS patients that took 40,000 IU per day and that led to a blood level of 400 ng/ml of 25(OH)D did not lead to increased calcium levels and did not lead to hypercalciuria (too much calcium in the urine). So, all of the papers that either indicated to the public that it would be unsafe or unnecessary to take vitamin D3 seem to have other agendas than communicating the truth. Had it been true that calcium would be released from the bones or calcium were absorbed too much from the gut, this would have caused calcification of the bones, soft tissues, heart and kidneys. Also, kidney stones would have developed. However, a low calcium diet combined with corticosteroid drugs usually leads to a full recovery within a month. Interesting that all of the dire predictions regarding toxic vitamin D3 levels did not materialize. Here is another website discussing vitamin D3 dosing.

I talked to a participant of the conference (who has a fellowship degree of the A4M) about what is really known about vitamin D3 toxicity. He told me that there has been an unintentional overdose where a compounding pharmacy made a mistake, so that a patient accidentally received a dosage of 500,000 Units of vitamin D3 per day for a full three months, before the mistake was uncovered. The patient felt sluggish, but did not have any other symptoms. He was told to stop the vitamin D3 compound. He had an uneventful recovery with no detrimental effects. At this point no overdose of vitamin D3 has been established.

Conclusion

Vitamin D3 is a vital supplement that has been shown to prevent not only rickets in children, but also depression, MS, infections and even many cancers (Ref. 4). As usual there will be many critiques that doubt the validity of the above statements. But I have found that all of these effects described above were confirmed in several sources of various medical information. Keep in mind that negative rumours have a tendency to linger on for years.

Calcium, Vitamin D3 and Vitamin K2 Needed For Bone Health

Recently there has been a lot of coverage in the press regarding postmenopausal treatment of women to prevent osteoporosis. It is all based on this original publication February 26, 2013.

Essentially, a number of studies were compared (a meta-analysis of several trials) where 400 IU of vitamin D and 1000 mg of calcium were given to postmenopausal women and osteoporotic fractures were measured as the end point for osteoporosis. The conclusion was that there was no value in taking these supplements to prevent osteoporosis. Many other media publications carried this story.

Just two days earlier (Feb. 24, 2013) another study was released with a much larger patient base of 36,282 postmenopausal women of the Women’s Health initiative in the US who were followed up for 7 years. Initially there was some confusion as to how compliant the patients were in taking the required 1000 mg of calcium carbonate and 400 IU of vitamin D3. The supplement compliant group when compared 7 years into the trial had 35% to 38% less fractures of the hip than the placebo group. This supplementation did not cause kidney stones in the study group as is often cited by some physicians as the reason why they do not want to recommend supplementing with vitamin D3 and calcium. In other words all of these kidney stone concerns you have so often read in the media are not true.

In order to make sense of supplementation for osteoporosis prevention I will first review what is known about bone metabolism, then I will comment on what is missing in some of the studies and why it still makes sense to supplement to prevent osteoporosis. I also will outline at the end of this blog what would be a sensible supplementation regimen based on a balanced review of the medical literature.

Calcium, Vitamin D3 and Vitamin K2 Needed For Bone Health

Calcium, Vitamin D3 and Vitamin K2 Needed For Bone Health

Bone metabolism

The skeleton of an average adult contains 1–1.3 kg of calcium and 99% of this is mostly in the form of hydroxyapatite. In order to absorb calcium from our food we need vitamin D3 to absorb calcium into the blood from the small intestine (Ref.1). To transport calcium from the blood into the bone we require both vitamin D3 and vitamin K2 (=menaquinone). This blog explains that several studies have shown that vitamin K2 (or MK-7) plays a double role of preventing calcification of the arteries and bringing the calcium into the bones of osteoporotic women.

Apart from Vitamin K2 that is necessary for osteoporosis prevention other factors have shown to be of importance. For instance, testosterone is an anabolic hormone (meaning a hormone that builds up) and it has clearly been shown that it is bone building: It does so by stimulating osteoblasts, which are bone producing cells that reside inside the bone.

But vitamin D3, vitamin K2 and strontium together have also been shown to build up bone density within one year.

So, how does vitamin K2 deposit calcium into the bone? It does so by stimulating a hormone, called calcitonin, which is produced by specialized C cells (parafollicular cells) inside the thyroid gland and released into the blood stream. Calcitonin arrives in the bone where it binds firmly with receptors of osteoclasts (bone remodeling cells), which stops breakdown of bone. Calcitonin is helped by another hormone, called osteocalcin, which is produced by the bone producing cells, called osteoblasts:

Osteocalcin levels in the blood can be measured and used as a research tool to see whether a medication is effective in building up bone mass density (BMD). Osteocalcin is a calcium-regulating hormone that is controlled by vitamin K2. If vitamin K2 is present, carboxylation of osteocalcin will lead to mineralization of the bone (new bone formation); if vitamin K2 is absent, osteoporosis sets in.

Vitamin K2 has a second function: it removes calcium from the arterial walls and tissues. How does it do this?

Matrix GLA protein is found in tissues of the heart, lungs, kidneys and blood vessels. When vitamin K2 stimulates carboxylation of this protein, it will function like a broom and clean out calcium deposits (calcification) from blood vessels and organ tissues. As vitamin K2 is needed for this carboxylation process, it appears that nature had in mind to remove calcium from soft tissue organs and blood vessels and form hydroxyapatite in the bone for bone strength. It seems that vitamin K2 is the key vitamin necessary to do this job. Another player is magnesium that is required for the normal function of more than 300 cellular enzyme systems. In terms of hormones the three hormones parathyroid hormone (PTH), vitamin D3 and calcitonin need to interact normally, all requiring magnesium as cofactor. In addition to this zinc, copper, boron, and manganese are needed as trace minerals to act as cofactors with regard to specific enzymes related to bone metabolism (Ref. 1).

In the aging person hormonal deficiencies are also factors for causing osteoporosis to develop. As this link shows, Dr. John Lee found bioidentical progesterone topical cream very helpful in women with respect to increasing bone mass density by 15% over 3 years.

In men bioidentical testosterone needs to be replaced when it is found to be low as well. So, bioidentical hormone replacement in both men and women is part of a bone health management program to prevent osteoporosis.

Some trials that demonstrate how you can build up bone

1) In this paper a protein similar to parathyroid hormone (parathyroid hormone–related peptide or PTH-rP) was used in combination with 1000 mg of calcium and 400 IU of vitamin D3 in a group of postmenopausal women with osteoporosis. Within 3 month of treatment there was an increase of bone mass density in the lower back (lumbar spine) of 4.7%, which translates into a yearly increase of bone mass density of 18.8%. In the past this has never been achieved with other agents. A variation regarding this topic is a medication, which is a parathyroid hormone  look-alike, called Teriparatide (PTH 1-34), which is given once daily as an injection of 20 mcg up to 2 years. It has been found useful in treating fractures of the vertebrae and other fractures in osteoporotic postmenopausal women (Ref.2).

2) This publication tells the story of how bone was built up just by adding vitamin K2 to the diet in a varied patient population from children to middle aged and older individuals with a variety of osteoporotic conditions in Mumbai, India.

3) In this paper the various effects of estrogens, selective estrogen receptor modulators, calcitonin and strontium ranelate were investigated with regard to their ability to build up bone when severe bone loss was caused by end stage osteoarthritis.

4) Postmenopausal women who received 800mg/day of calcium citrate, along with various levels of intensity of a structured exercise program, increased their muscle mass by 11% to 21% and increased their BMD by approximately 2%.

5) Calcitonin is very effective in reducing bone pain when the patient has compression fractures from osteoporosis; it is given as an intranasal spray of 200 units daily (Ref. 2). However on March 5, 2013 the FDA announced that salmon calcitonin would not be safe for humans as there is a slight risk that cancer can develop as a “side-effect”.

6) According to Ref. 2 strontium ranelate has been used in Europe in the treatment of postmenopausal osteoporosis. It was shown to build up bone and to decrease the amount of bone resorption. Side effects include nausea and diarrhea.

The team players of bone metabolism to build strong bone

We are now in a position to analyze why the researchers of the first paper cited in the beginning of this blog came to the conclusion that calcium and vitamin D3 supplementation were not enough to make a statistical difference in the treatment of postmenopausal women when compared to placebos. As explained bone metabolism is a complex process involving several team players, where the key player is vitamin K2, which was completely ignored in that study. The examples I mentioned above in point form show that exercise and calcium are also important. Vitamin K2 by itself worked quite well as it is so powerful. Hormones like PTH and calcitonin are effective, but more difficult to take for the average consumer and the FDA now has banned calcitonin. Vitamin D3 has been shown to be important both for absorption of calcium from the intestine and also for depositing calcium into the bone together with vitamin K2. The WHI study mentioned above is highly significant because of a 1/3 reduction of hip fractures after 7 years of vitamin D3 and 1000 mg of calcium per day supplementation. If you add vitamin K2, exercise and bioidentical hormone replacement in postmenopausal women who need it, the prevention of hip fractures, wrist fractures and vertebral compression fractures likely will be as high as 50% in those who are taking their supplements regularly (compliance issues like forgetting the supplements or deliberately not taking them were mentioned in several of the studies). With the right supplementation, which includes vitamin K2 as mentioned above, you achieve that you lower your heart attack and stroke risk as the vitamin K2 removes the calcium from the blood vessels and deposits it into the bones, while at the same time strengthening your bones. Attention to proper nutrition, exercise and your hormone balance (using only bio-identical hormones to replace what’s missing) will also reinforce osteoporosis prevention. The bonus of using bioidentical hormone replacement therapy is that you prevent heart attacks and strokes in addition to preventing osteoporosis. I think that this is a good deal!

An easy-to-follow osteoporosis prevention program

The best combination is 1000 mg (or 1200 mg as per National Osteoporosis Foundation recommendation) of calcium per day together with 400 to 800 IU of vitamin D3 (for cancer prevention you may want to take 4000 IU to 5000 IU of vitamin D3 per day instead monitored by a 25-hydroxyvitamin D blood level test through your physician) and 100 to 200 micrograms of vitamin K2 (also called MK-7). In the age group above 50 missing hormones such as bioidentical testosterone in men and bioidentical progesterone/estrogen combinations in women should be given as well. This works best, if you also watch your weight, cut down your alcohol consumption to a minimum (or better cut alcohol out altogether), exercise regularly (this builds up bone and muscle strength) and stick to a balanced diet resembling a Mediterranean or zone type diet (low-glycemic, low fat, wheat free and no sugar).

If you want to age gracefully, you need not only a healthy heart and a healthy brain, but also healthy bones as this prevents disabilities.

I received the following feedback on Nov. 10, 2013:

 Dr Ray, I read your March 17 Blog entry which suggested 100 ug of Vitamin K2 with 5000 IU of D3.   I have atherosclerosis and have radically changed my diet (plant only), but also now take an average of about 3000 IU of Vitamin D3. Dr. Kate Rhéaume-Bleue (book on K2) recommended taking about 200 ug per day of K2, but increasing K2 to about 1,000 ug if taking around 5,000 IU of D3 to ensure proper activation of MGP. What is your opinion with regard to a D3/K2 ration?  Thank you

 Answer from Dr. Ray on Nov. 12, 2013:

I appreciate your question about what doses of vitamin K2 to take. There are varied recommendations, but I like to go by human trials and what they have actually shown. In this review in 2010 from the Life Extension Magazine a study is cited that showed that only 45 micrograms of vitamin K2 was enough to get the calcium out of the arterial walls and into the bones.

Dr. Mercola has reviewed the literature and found that most investigators were now using 180 to 200 micrograms, but he added that there is no real good literature substantiating that. I like to go by the golden rule to “do no harm”, so I myself take 100 micrograms per day of vitamin K2 along with 5000 IU of vitamin D3. I have my 25-hydroxy-vitamin D3 levels done every few months to make sure the vitamin D level is well above 50, but not too high.

Remember that other risks for cardiovascular disease are sugar and starch consumption (the liver turns this into triglycerides and too much LDL cholesterol). I also avoid wheat because of the gliadin content, which gets you addicted to wheat and sugary foods,  and the lectin content, which can cause leaky gut syndrome and autoimmune illnesses. I also stay away from too much beef (I only eat grass fed, antibiotic free beef), but rather prefer to eat organic chicken, turkey and lean pork. I understand that you have a plant only based diet, but I would recommend to you to reconsider that. At least have your ferritin level checked from time to time, so you do not miss an iron deficiency that could develop. For other readers: Don’t forget your vegetables (organic, please).
