Resveratrol Effective In Humans

Resveratrol is a powerful antioxidant; but is resveratrol effective in humans?

  1. Quack watch says: don’t buy into the hype that resveratrol is effective in humans.
  2. WebMD claims that there would not be enough medical evidence to say that the average person should supplement with resveratrol to receive benefits.

Despite these recommendations the following evidence supports that resveratrol is indeed effective in humans.

Resveratrol effective in humans: high blood pressure patients

First of all, a 2017 study of high blood pressure patients examined resveratrol supplementation with two groups, 46 stage 1 hypertension patients and 51 stage 2 hypertension patients. Stage 1 hypertension had a systolic blood pressure of 140–159 mmHg and a diastolic blood pressure of 90–99 mmHg. Stage 2 hypertension had a systolic blood pressure of 160–179 mmHg and a diastolic blood pressure of 100–109 mmHg. Analysts divided both stage 1 and 2 subgroups into two groups, one receiving regular antihypertensive medication, and the other group receiving regular antihypertensive medication plus Evelor. Evelor is a micronized formulation of resveratrol. The trial lasted two years.

Blood pressure lowering effect of resveratrol

The purpose of the trial was to determine the effect of resveratrol.  added to the regular antihypertensive medication (or not) to see whether it had blood pressure lowering effects. The interesting result showed that the resveratrol addition was sufficient to bring the blood pressure down to normal levels with only one antihypertensive drug. The control group without resveratrol needed two or three drugs to get the blood pressure under control. In addition, liver function tests showed that resveratrol normalized negative side effects of the antihypertensive drug on the liver. Both liver enzymes, glutamate-pyruvate transaminase (SGPT) and gammaglutamyl transferase (Gamma-GT) were normal in the resveratrol group.

Resveratrol effective in humans: diabetes patients

Diabetes patients can get help with resveratrol. Resveratrol, the bioflavonoid from red  wine is a powerful anti-inflammatory. This antioxidant has several other effects, which make it challenging to measure each effect by itself. Another group of investigators managed to simultaneously measure these effects. They found that resveratrol lowered the C-reactive protein by 26% and tumor necrosis factor-alpha by 19.8%. Resveratrol also decreased fasting blood sugar and insulin; in addition it reduced hemoglobin A1C and insulin resistance. The recommended daily dose of resveratrol was 1000 to 5000 mg.

Resveratrol effective in humans: improves bone density

Furthermore, resveratrol improves bone density in men: 66 middle-aged obese men with an average age of 49.3 years and a mean body mass index of 33.7 were recruited for this randomized, double blind, placebo-controlled trial. The purpose was to study whether there would be changes in bone turnover markers (LDH, an enzyme involved in bone turnover), but also whether bone mineral density (BMD) would increase. The researchers gave resveratrol to a high group (1000 mg per day), a low group (150 mg) and the third group received a placebo (fake pills). The end point was an elevation of the bone alkaline phosphatase (BAP). The investigators measured this in the beginning of the study and at 4, 8 and 16 weeks.

Difference between high and low dose resveratrol

The high group of resveratrol had a 16% increase of the BAP throughout the study and a 2.6% in lumbar spine bone density (measured by a trabecular volumetric method). The low resveratrol group showed no bone restoring effect. MJ Ornstrup, MD, the lead investigator said that this was the first time that a clinical team has proven that resveratrol can serve as an anti-osteoporosis drug in humans. She added that resveratrol appears to stimulate bone-forming cells within the body.

Resveratrol effective in humans: anti-aging effects

Finally, the Nurses’ Health Study showed that both a Mediterranean diet and resveratrol can elongate telomeres.

The fact that you can have a longer life with a Mediterranean diet is common knowledge for some time. But now a study has shown that the reason for a longer life is the fact that telomeres get elongated from the Mediterranean diet. Telomeres are the caps at the end of chromosomes, and they get shorter with each cell division. This is the normal aging process.

Important information from the Nurses’ Health Study 

The finding of elongated telomeres comes from the ongoing Nurses’ Health Study that started enrolling subjects in 1976. At that time 121 700 nurses from 11 states enrolled in the study. In 1980 participants filled in diet sheets to determine who was adhering to a Mediterranean diet. The researchers accepted 4676 middle-aged participants in this study. This diet consists of a combination of vegetables, legumes, fruits, nuts, grains and olive oil. They also consumed fish and lean meats. The control group followed a regular diet. Between 1989 and 1990 blood tests were obtained to measure telomere length in white blood cells. It is known that smoking, stress and inflammation shortens telomeres.

Slowed telomere shortening

The lead author Marta Crous-Bou stated that overall healthy eating was responsible for longer telomeres in comparison to the control group. But the strongest association was in women eating a Mediterranean diet in comparison to the controls. For the best diet adherence score there was a 4.5 year longer life expectancy due to slowed telomere shortening.

Resveratrol lengthens telomeres

Longer telomeres associated with the lowest risk to develop chronic diseases and the highest probability of an increase of the life span. I have reviewed the importance of lifestyle factors in this blog where I pointed out that Dr. Chang found a whole host of factors that can elongate telomeres by stimulating telomerase. Research in humans supports the notion that an increase in physical activity elongates telomeres. So did vitamin C, E and vitamin D3 supplementation, resveratrol, a Mediterranean diet and marine omega-3 fatty acid supplementation. In addition higher fiber intake, bioidentical estrogen and progesterone replacement in aging women and testosterone in aging men, as well as relaxation techniques like yoga and meditation are also elongating telomeres.

Aging is due to shortening of telomeres. Elongation of telomeres by resveratrol leads to prolonged life (or anti-aging).

Resveratrol effective in humans: resveratrol and cancer

In addition, this overview shows, it seems that several mechanisms of action give resveratrol the power to be an anticancer agent. Resveratrol is anti-proliferative and has anti-angiogenesis mechanisms. In addition resveratrol stimulates apoptosis, which is programmed cell death. All these actions together help resveratrol to have anticancer properties. Resveratrol is also useful in combination with other cancer treatments, which improves survival figures. As the link above explains, there is a need for more cancer clinical trials with a variety of cancers and larger patient numbers. Many smaller clinical trials have already been very successful showing efficacy of resveratrol as a chemotherapeutic agent.

Resveratrol is anti-inflammatory

Also, in this 2015 publication about malignancies and resveratrol an overview is given about the use of resveratrol and cancer treatment. It summarizes that the development of cancer is a multifactorial process that involves the 3 stages of initiation, promotion and progression. One of the cancer promoting factors is chronic inflammation. Resveratrol has anti-inflammatory qualities. At this point it is not clear how the animal experiments will translate into the human situation. More clinical observations are necessary.

Resveratrol effective in humans: cardiovascular disease

Resveratrol has beneficial effects on preventing hardening of the arteries, diabetes, various cancers and inflammatory conditions like Crohn’s disease and arthritis. Furthermore,  as this link explains resveratrol also stimulates the antiaging gene SIRT1 by 13-fold. This confirms the anti-aging effect of resveratrol. This 2012 study confirmed that it is resveratrol from red wine that is responsible for the “French paradox” (longer life expectancy despite high saturated fat intake).

Resveratrol effective in humans: polycystic ovarian syndrome 

Similarly, polycystic ovarian syndrome could be significantly healed with resveratrol in a randomized, double blind, placebo-controlled trial. It involved 30 subjects who completed the trial. Each of the subjects received 1500 mg of resveratrol or placebo daily for 3 months. Measurements showed a decrease of serum total testosterone by 23.1% at the end of 3 months in the experimental group versus the placebo group. There was also a decrease of dehydroepiandrosterone sulfate of 22.2%.There was a reduction of the fasting insulin level by 31.8%. At the same time there was an increase of the insulin sensitivity by 66.3%. The authors concluded that resveratrol had significantly reduced ovarian and adrenal gland male hormones (androgens). This may be in part from the drop in insulin levels and the increase of insulin sensitivity.

Resveratrol effective in humans: anti-arteriosclerotic effects in diabetics

Most noteworthy, a double blind, randomized, placebo-controlled study was done on 50 diabetics. Arterial stiffness was determined by the cardio-ankle vascular index (CAVI). The purpose of this study was to determine the effect of resveratrol on the stiffness of arteries in a group of diabetics and compare this to a placebo. Diabetics have premature hardening of the arteries (arteriosclerotic changes). After 12 weeks of taking 100 mg of resveratrol per day there was a significant reduction in arterial stiffness in the experimental group, but not in the placebo group. Blood pressure also decreased by 5 mm mercury (systolic) in the experimental group.

Resveratrol effective in humans: ulcerative colitis patients

Finally, 56 patients with mild to moderate ulcerative colitis received 500 mg of resveratrol or placebo and were observed for 6 weeks. This was a randomized, double blind, placebo-controlled pilot study. The researchers used bowel disease questionnaires to assess the bowel disease activity before and after the treatment. The resveratrol group decreased the disease activity significantly, but it also increased their quality of life. Blood tests showed that this improvement occurred as a result of reducing oxidative stress by resveratrol.

Resveratrol effective in humans: Alzheimer’s disease prevention

Here is a study where 52 Alzheimer’s patients were divided into two groups; one group received 200 mg of resveratrol for a number of weeks, the other group placebo pills. There was a significant improvement in memory tests in the resveratrol group and functional MRI scans showed better functional connectivity in the hippocampi of the subjects. The hippocampus is the seat for short-term memory, which is not functioning normally in Alzheimer’s patients.

Resveratrol Effective In Humans

Conclusion

Resveratrol has a long history of showing evidence of improving health. It does so by countering oxidation of LDL cholesterol, which lessens hardening of arteries. This prevents heart attacks and strokes. Resveratrol is also a powerful anti-inflammatory, which helps patients with diabetes, with Crohn’s disease and arthritis. There is even a cancer preventing effect of resveratrol because of anti-proliferative and anti-angiogenesis effects as well as stimulating apoptosis. These combined anticancer properties make resveratrol a chemotherapeutic agent. It is also effective in combination with conventional anticancer drugs.

Resveratrol helps prevent hardening of arteries and cancer

There are enough randomized, double blind, placebo-controlled trials in humans to show that resveratrol is effective in preventing and treating several disease conditions. The medical establishment claims that there would not be enough medical evidence to say that the average person should supplement with resveratrol to receive health benefits. After my review outlined above I come to the opposite conclusion. It is quite clear that resveratrol has several important healing properties. It can improve diabetes; prevent hardening of arteries, lower blood pressure, attack osteoporosis and prevent Alzheimer’s disease. I have been taking 500 mg of resveratrol daily for years. It has not harmed me.

Testosterone

One of the driving hormones in a man is testosterone. We also know that with age this hormone level falls. The lesser known fact is the importance of monitoring testosterone levels in aging males. This way they have the choice of intervening with the aging process. Here are the facts about testosterone and about replacement of it when it is low. I will also discuss the anxieties of the medical profession to deal with this. Some feel uncomfortable about hormone replacements.

Androgen receptors contained in key tissues

Androgen receptors are situated in the key organs like the brain, heart, muscles, bones, kidneys, fat cells, genitals, hair follicles and skin. They respond to all male hormones, called androgens, like testosterone, dihydrotestosterone (DHT) and DHEA. DHT is produced by metabolizing testosterone with the help of an enzyme, called 5α-reductase in the adrenal glands. This is responsible for hair loss in males and some females. There is a genetic factor for this. It is important that the man continues to have all tissues stimulated by his male hormones when he ages or the key organs mentioned are going to suffer.

A lack of testosterone as the man ages (around 55 to 65) leads to a slowdown in thinking, osteoporosis in the bones, muscle atrophy (melting in of muscle tissue), and a lack of sex drive. Mood swings can turn the male into the “grumpy old man”. The skin gets thinned and is more brittle.

Animal experiments have shown that the development of fatty streaks in blood vessels happens at a higher rate in castrated animals. The more encouraging finding in these animals is the fact that this condition is reversible by replacement of the male hormone. In healthy males of a younger age all organs are working well. The problems starts when males age and the hormone regulation in the brain slows down, which ultimately leads to andropause in males, the equivalent of menopause in women. When the physician replaces testosterone in an aging man who has low testosterone levels, the stimulation of androgen receptors in key organs, which I mentioned before return organ function to normal.

Reluctance of physicians to prescribe testosterone

In the past medical students were taught that testosterone is causing prostate cancer. This was based on old observations by Dr. Huggins, a Canadian born surgeon who practiced in Chicago, that orchiectomy improved the survival of advanced prostate cancer patients by a small percentage. Dr. Lee pointed out that Dr. Huggins neglected to realize that testicles make both the male hormone and small amounts of estrogen.

History of hormone ablation therapy for prostate cancer

When an orchiectomy was done (because of the belief that testosterone production was the culprit) inadvertently the real cause of prostate cancer (an estrogen surplus) was also removed thus improving the survival of these patients somewhat. Nowadays we have more sophisticated testing methods. Dr. Abraham Morgentaler (Ref. 1) has compiled a lot of evidence about the importance of testosterone in men. He proved, based on a lot more modern references that it is not testosterone that is the cause of prostate cancer. We know now that estrogen dominance is responsible for prostate cancer and that this develops as stated above because of the low testosterone and low progesterone during the male menopause (also called “andropause”).

Rebuttal of Dr. Huggins’ research

Dr. Morgentaler, a urologist from Harvard University has taken prostate cancer patients and put them on testosterone. To his and everyone else’s surprise testosterone treated prostate cancer patients improved, their prostate cancer either disappeared or become much less aggressive, which can be measured with the Gleason score based on its microscopic appearance. The result was that they did better, not worse on male hormone replacement.

Older physicians still hold on to the belief that testosterone would make prostate cancer worse

Unfortunately the history of testosterone, orchiectomy and prostate cancer as explained led to confusion among the medical profession. We now know that testosterone is innocent with respect to prostate cancer, testicular cancer or any other cancer. But some of the old-timers among the physicians doggedly hold on to their false belief from the past. If a man asks one of these physicians for testosterone replacement he may not only be told that he/she could not do that, but will also receive a tirade of false statements about testosterone.

No blood clots with male hormone replacement

We dealt with the myth of prostate cancer that is not related to treatment with the male hormone. There is another myth that older physicians often cite: that testosterone would supposedly be causing blood clots. At the University of Texas Medical Branch at Galveston (Texas, USA) a large study was done involving 30,572 men, ages 40 years and older. All had venous thromboembolism and received an anticoagulant drug or an intravascular vena cava filter following their diagnosis. Because they also had a low testosterone level physicians gave them testosterone replacement therapy. In addition, they followed them and monitored them for further venous thromboembolism. None were found in any of the men. The conclusion of the investigators was that filling a testosterone prescription was not associated with any clotting condition.

Aging and testosterone

The Massachusetts Male Aging Study showed that testosterone has been declining in the male population over a period of 20 years. Partially there is a relationship to aging. Otherwise estrogen-like substances or xenoestrogens, which are environmental factors, contribute to it as well. Although age is a factor, there is so much variation from man to man, that it is best to just measure testosterone and determine whether the mail hormone level is above or below 500 ng/dL. This seems to be the most reliable indicator in determining whether a man needs hormone replacement, apart from symptoms due to testosterone loss. These are: increased risks for prostate problems and/or cancer, cardiovascular disease, loss of bone density, a rise in cholesterol and urinary dysfunction. Dr. Randolph describes this in detail and also discusses who needs bioidentical testosterone replacement.

The aging male and hormone replacement

A New England Journal of Medicine study from September 2013 explained that apart from testosterone the male body needs a small amount of estradiol, the female hormone. The enzyme aromatase within the fatty tissue achieves this. But the physician must prescribe testosterone replacement as the bioidentical testosterone, so that a small amount of it converts into estradiol by the action of aromatase. Synthetic male hormone compounds with chemical side chains do not provide this small estrogen metabolism.

After a review of the hard facts about prostate cancer risk, it is now clear that older men get prostate cancer because testosterone in their blood is low and their body weight elevation. The extra fat converts androgens by the aromatase into estradiol. This leads to estrogen dominance. This causes breast cancer and uterine cancer in women, prostate cancer in men. When the total testosterone level in a man is lower than 500 ng/dL it is a sign that he needs male hormones to protect his prostate from prostate cancer.

Cardiovascular disease

The cardiovascular system has a lot of androgen receptors on its cell surfaces. It is important that the man continues to have the proper stimulus from androgenic hormones (testosterone, dihydrotestosterone and DHEA). This will allow him to have proper contractility of heart cells. It will also allow for relaxation of smooth muscle cells in the arteries to control blood pressure. With a lack of male hormones there is hardening of the arteries, loss of muscle cells in the heart muscle and increase of blood pressure. So far researchers have only noticed an association of low testosterone with diabetes, high blood pressure and heart attacks. It has not been proven that it is the cause (so webmd.com says). But careful replacement with bioidentical testosterone helps patients to get rid of their symptoms, have the energy to exercise and feel better.

Is it safe to replace missing hormones in a male?

Long-term studies have already shown that hormone replacement saves lives, but the medical profession is slow to accept this (Ref.1). Here is a link that explains this a bit further.

If a man who is low in male hormones wonders whether it would be worthwhile to go on testosterone therapy, here is the clear answer: would you like to have a 47% lowered risk of dying, a reduction of 18% in heart attacks and 30% reduction in the risk for a stroke? This is what a 14-year follow-up study published in the European Heart Journal in August, 2015 found.

The same is true for cardiovascular disease as stated above: if the total testosterone level in a man is lower than 500 ng/dL it is a sign that he needs testosterone replacement therapy to protect his cardiovascular system to prevent heart attacks and strokes.

Loss of bone density

Older men can get osteoporosis, which can lead to compression fractures in the spine. In addition fractures can also occur in the hip, the ankle or wrist. Current thinking is that with the lack of male hormones there is also a lack of estradiol via the aromatase pathway in fatty tissue. This small amount of estradiol is able to prevent osteoporosis all his life until testosterone drops with older age. Once again it is important to monitor his male hormone level and replace with bioidentical testosterone when it is lower than 500 ng/dL.

Rise in cholesterol

With obesity there is a metabolic change, called metabolic syndrome. This leads to an elevation of LDL cholesterol, which is a direct risk for hardening of the arteries. In an obese older man with low male hormones there is a double risk. First, there is the low testosterone and secondly the metabolic syndrome, if he is overweight or obese. As a result the heart attack and stroke rates in obese men with low testosterone are much higher. In obese men with normal male hormone levels there are less heart attacks and strokes. Men with obesity need to lose weight by changing their diet to healthier eating habits and starting a regular exercise program with swimming and walking. At the same time those with a testosterone level of lower than 500 ng/dL should have bioidentical testosterone replacement.

Urinary dysfunction

A hyperactive bladder, dribbling, hesitancy and leaking bladder can all be part of male hormone deficiency. But this is not that easy to diagnose. A full consultation by a urologist may be necessary to assess various other causes that could hide behind these symptoms. Part of the work-up though is to measure the total testosterone level and replace what is missing.

Alzheimer’s disease

Alzheimer’s disease can be due to a lack of male hormones. It is therefore important to measure the total testosterone level in a man. If it is lower than 500 ng/dL, as mentioned before , it means he needs male hormone replacement therapy. This will prevent Alzheimer’s disease.

Burnout

According to Dr. Thierry Hertoghe, an endocrinologist from Belgium, there are several hormones that can be missing in a person with burnout: a lack of cortisol, thyroid, growth hormone, testosterone/estrogen, progesterone and oxytocin. The middle-aged manager with burnout would have other hormones missing apart from testosterone. The physician needs to order blood tests to measure whether other hormones are missing. Whatever is low needs replacement with bioidentical hormones.

Some details regarding testosterone measurements and delivery

The deeper you delve into male hormone replacement, the more details there are to consider.

First, there is a sex hormone-binding globulin that is mostly produced by the liver and circulating in the blood.

It is like a storage form of testosterone and only 1 to 2% of the total testosterone is unbound. This is called the free or bioavailable testosterone. Some physicians measure just that portion of testosterone.

Hormone replacement in a man

Second, when it comes to replacement of testosterone in a man who is deficient for testosterone, there are several delivery systems, which some people find a little confusing. There are testosterone gels with less than optimal absorption. Another application are creams that compounding pharmacies provide. The patient absorbs these creams are usually well. But some men do not absorb either creams or gels. They need testosterone injections or testosterone pellets. The goal is to replace testosterone in a manner that there is a fairly equal amount of testosterone available at all times. Some men achieve that only with testosterone pellets, others with testosterone cypionate injections. For this reason blood test that determine the levels of free testosterone are necessary.

Testosterone

Testosterone

Conclusion

Testosterone is a key hormone in the male that requires monitoring, particularly when he is aging. A knowledgeable physician or naturopath needs to take a careful history of his symptoms. If blood tests show that the total testosterone is less than 500 ng/dL the physician needs to replace with bioidentical testosterone.

The Full Story About Testosterone

Much has been written about what happens when women get into menopause. This begs the question: do men experience a change of life? As a matter of fact, they do. It is called “andropause”, and they can experience problems as a result. Here is a study from the Massachusetts General Hospital in Boston, MA, which was published in the New England Journal of Medicine (Sept. 2013) describing in detail what happens when men get into andropause (the male equivalent of the menopause).

We know from other studies that in obese men testosterone is converted into estrogen because of the enzyme aromatase that converts testosterone into estrogen resulting in erectile dysfunction and loss of sex drive. In lean men above the age of 55 there is a true testosterone reduction because the testicles produce less testosterone. This results in less sex drive, moodiness and lack of energy. But these men will do well with bioidentical testosterone replacement.

Main findings of the Massachusetts General Hospital study:

  1. Testosterone was responsible for thigh muscle development and leg press strength, for erectile function and sexual desire.
  2. Surprisingly, estradiol (the main estrogen component in both sexes) plays a significant part in sexual desire in the male. This became particularly apparent in the post-andropause male who desired hormone replacement. When bioidentical testosterone is used to replace what’s missing there was no problem with sexual desire or erectile function as a small amount of the testosterone was aromatized into estradiol. The researchers were able to measure both testosterone and estradiol levels.
  3. Here is a surprising fact: a lack of estrogen leads to abdominal obesity. This could also be verified by hormone measurements.
  4. In the past doctors used synthetic testosterone products like methyltestosterone, danazol, oxandrolone, testosterone propionate, testosterone cypionate or testosterone enanthate. The problem with these synthetic testosterone products is that the body cannot metabolize a portion of them into estrogen that is desirable for a normal sex drive, so the testosterone compounds alone are not doing their job as well as the bioidentical testosterone that the body can aromatize.

In obese men the problem is that there is too much estrogen in the system, which leads to a disbalance of the hormones in the male with a relative lack of testosterone. Overweight and obese men produce significant amounts of estrogen through aromatase located in the fatty tissue. Aromatase converts testosterone and other male type hormones, called androgens, into estrogen. Excessive levels of estrogen cause breast growth, muscle weakness, lead to abdominal fat accumulation, heart disease and strokes. Dr. Lee described what happens in men who enter andropause years ago as indicated under this link.

The Full Story About Testosterone

The Full Story About Testosterone

Testosterone to estrogen ratio:

Dr. Lee indicated that in his opinion saliva hormone testing is more reliable than blood tests (Ref. 1). One of the advantages of doing saliva hormone tests of estrogen and testosterone is that you can calculate directly the ratios of these two hormones. In hormonally normal younger males the testosterone to estrogen ratio is larger than 20 – 40 (Ref.2). The testosterone to estrogen ratio in obese men is typically less than 20 meaning it is too low. But lean men in andropause produce too little testosterone and their testosterone to estrogen ratio is also less than 20, because they may still have enough estrogen in their system from aromatase in the fatty tissue, but they are lacking testosterone due to a lack of its production in the testicles (Ref. 1 and 2).

When a man in andropause is given bioidentical hormone replacement with a testosterone gel or bioidentical testosterone cream this is absorbed into the blood and body tissues and then partially metabolized into a small amount of estrogen. This can be seen when saliva hormone tests are done; a higher level of testosterone is detected and much lower estrogen level so that the testosterone to estrogen ratio is now 20 to 40 or higher and the affected person will no longer be the “grumpy old man” that had been a source of distress to his partner before.

This New England Journal of Medicine study is important because it confirmed what anti-aging physicians had been saying for years: a small amount of estrogen is necessary for the male for bone health as estrogen receptors will regulate the bone density, it also helps for a normal sex drive. The same is true for women: a small amount of the opposite hormone (testosterone) will help a woman’s sex drive, but she needs the right mix of progesterone to estrogen (a progesterone to estrogen ratio of 200:1 using saliva tests) to feel perfectly normal as a women.

Health and well-being of a man depend on normal testosterone levels:

It is important to realize that testosterone is not only supporting a man’s sex drive and libido, key organs like the heart, the brain and blood vessels contain testosterone receptors as well. The body of a man was designed to respond to testosterone all along. It is when testosterone production is no longer keeping up that premature aging becomes apparent, as the target organs do no longer receive the proper signals.

A healthy heart in a man depends on regular exercise and testosterone stimulation whether he is young, middle aged or old. The same is true for the lining of the arteries where testosterone receptors are present to help with the normal adjustment to exercise and relaxation. The brain cells have receptors for all of the sex hormones and in a man they are used to higher levels of testosterone and lower levels of progesterone and estrogen. If you take the balance away, the aging man will feel miserable and grumpy. Depression will set in. Here is a brief review how one man’s life has been changed by testosterone replacement.

So, bioidentical hormone replacement is not just a matter of replacing one hormone, you need to pay attention to all of the hormones. Lifestyle issues enter the equation as well. I have reviewed the issue of bioidentical hormone replacement for women and men in this blog.

Conclusion:

When a man reaches the age of 55 or older there comes a point where a lack of testosterone and estrogen sets in. It is wise to start doing intermittent blood or saliva hormone tests before this point is reached in order to gage when bioidentical hormone replacement treatment should be given. Along with an assessment regarding the hormone status it would be wise to also assess lifestyle issues as often other factors play a role in premature aging. I have reviewed these factors systematically in a recent publication (Ref. 3). It is best to combine bioidentical hormone replacement with life style interventions to achieve optimal preservation of a man’s health.

Bone Loss Non Reversible After Provera

Depo-Provera has been used as an injectable form of contraception, but the manufacturer (Pfizer Canada Inc.) has sent out warnings to physicians about some quite serious side effects. New data have shown that after two years of use significant bone density loss can be seen.

What is more alarming is the fact, that this loss does not seem to be fully reversible, even if the medication is stopped. The effect is bad enough for adults, but it becomes even more alarming should adolescents receive the product: at a time when they should build their bone density, they would be experiencing the problem of bone density loss!

The amounts of bone mineral density is not insignificant: a controlled clinical study showed that women, who received the medication for 5 years showed a decrease of bone density in the spine and hip of 5 to 6 %. If the drug was stopped, there was a partial recovery of the loss, but the longer the drug was used, the less favorable was the recovery of bone density.

There has been some awareness in the past, that loss of bone density could be a risk in the use of Depo-Provera, but there was the thought that all would be well after discontinuing the medication.

Bone Loss Non Reversible After Provera

Bone Loss Non Reversible After Provera

This however is not the case after the new research data, and it should caution women to stay away from this form of birth control, if they are interested in maintaining good bone health.

More information about osteoporosis: http://nethealthbook.com/arthritis/osteoporosis/

Reference: The Medical Post, December 7, 2004, page4

Comment on Dec. 7, 2012: Depot Provera belongs into the progestin type hormone equivalents of progesterone (= the natural ovarian hormone). A young female who has normally functioning ovaries has strong bones as both estrogen and progesterone stimulate bone formation by stimulating receptors on the osteoblasts, cells that make new bone. Artificial hormone products like the progestins do not stimulate these receptors, they may even block them. So, women should stay away from Depot-Provera and other Big Pharma contraceptives, as they will contribute to osteoporosis. On the other hand when a woman enters the menopause, she requires full replacement with bio-identical estrogen/progesterone creams to stimulate bone formation and to prevent osteoporosis. There is still a lot of misinformation around in the public, often because of misinforming “infomercials” from Big Pharma.
