Vitamin D and Testosterone Levels

A new study appears to show a link between healthy vitamin D intake and healthy testosterone levels, and/or a link between low vitamin D levels and low testosterone. Which is it? More research is needed, say the scientists who conducted the study.

Vitamin D and Testosterone Levels

Vitamin D Deficiency has already been shown to lead to an increased propensity for developing dozens of different illnesses, diseases and other conditions. Conversely, healthy levels of vitamin D3 by way of sun exposure or supplementation have been shown to help strengthen the immune system and stave off numerous diseases. Well, theres more news on the vitamin D front, and this latest news involving the miracle sunshine vitamin appears to bode especially well for men particularly those whose age is at (or in excess of) the age at which testosterone levels typically begin to decline in males.

Testosterone and Vitamin D

Testosterone is the male sex hormone, and low levels can result in a decreased sex drive, metabolic slowing and decreased muscle mass, among other things.

The most recent news is that high serum levels of Vitamin D have been clinically shown to boost testosterone levels in men. This according to a new study conducted by Katharina Nimptsch and associates at the Harvard School of Public Health[1], and which was published in the Journal of Clinical Endocrinology earlier this year.

In their report on the trial, Nimptsch and company suggested that vitamin D may increase the production of testosterone in men, and experimental animal studies and at least one cross-sectional study appear to show a positive link between plasma 25-hydroxyvitamin D or 25(OH)D and testosterone production in men. The scientists determined that once vitamin D levels reached the point of 75 to 85 nmol per liter, the relationship with increased testosterone production appeared to taper off.

A similar association was also observed between levels of serum vitamin D and free testosterone.

At lower levels, the amount of the increase in testosterone production was proportionate to the increase in vitamin D levels, which in the study were ingested in the form of vitamin D3 supplements.

Vitamin D3 is the form of vitamin D obtained through sun exposure and a process of internal synthesis involving the bodys vitamin D receptors. D3, also known as cholecalciferol, is the most readily absorbed form of vitamin D available as a supplement, and is far more effective than the synthetic vitamin D2, the use of which as a supplement in humans has become controversial in recent years.

Testosterone Vitamin D

The scientists who conducted the trial stopped short of asserting a definitive causality between increased vitamin D3 intake and increased testosterone levels. The report made it a point of clarifying that more research is needed to determine whether the relationship between increased vitamin D intake (or synthesis if obtained from sunlight) results in increased testosterone, or if low testosterone is merely a byproduct of low vitamin D to begin with. While this may appear to be a tomato-tomahto argument for some, the scientists were careful to assert that more research was needed before any sort of causality between vitamin D levels and testosterone levels could be established.

In the scientists own words:

This study supports previously reported positive associations between vitamin D and testosterone although we did not observe parallel seasonal variation patterns. Possible causality and direction of the vitamin D-testosterone association deserve further scientific investigation.

In any case, testosterone-boosting medications and supplements have become a booming industry over the past couple of years, and it is possible that men across the country and world may be unnecessarily paying excessive prices for doctors visits, testosterone-enhancing medicines and high-end supplements which may have adverse side-effects. If all that is needed to achieve healthy testosterone levels is increased sun exposure and/or a high-quality vitamin D3 supplement, then hundreds of thousands if not millions of men could be saving hundreds of dollars while safely and naturally achieving the same ends (increased levels of testosterone, the male sex hormone) without all the risks, negative side-effects and foreign chemicals found in some of these other testosterone boosting medicines and supplements.

Schizophrenia Linked to Vitamin D Insufficiency

Schizophrenia Linked to Vitamin D Insufficiency

By: Pamela Egan

A new study out of Iran has determined that individuals suffering from inadequate serum levels of vitamin D have more than double the chances of becoming schizophrenic than do people who obtain healthy amounts of the letter vitamin/hormone.

Low Vitamin D Serum Levels Doubles Chances of Becoming Schizophrenic

Vitamin D-3 Drops (Supplement)Unlike a traditional study, the research published July 22 in the Journal of Clinical Endocrinology and Metabolism constitutes what is known as a “meta analysis”. In a meta analysis, unlike a traditional experiment, study or clinical trial, instead of conducting original research using volunteers (test subjects), a control group and different variables to determine how the different variables react (or don’t react) to the volunteers under various circumstances; the researchers instead review previously conducted research. The objective is to review numerous studies which are similar in nature in an attempt to discern any patterns or other data that may surface in the presence of macro-data that may not be as obvious within the context of a single study.

In this particular instance, the researchers reviewed 19 different studies encompassing a combined total of over 2,800 people studied. The purpose of the research was to determine if any discernible link could be established between vitamin D deficiency and schizophrenia.

The scientists were surprised to discover that not only does vitamin D deficiency predispose an individual to developing schizophrenia, a grouping of psychiatric disorders characterized by among other things hallucinations, difficulty speaking, delusions and disoriented thoughts, but did so by a substantial margin. As it turns out, those who suffer from insufficient levels of vitamin D (which is actually a hormone – not a vitamin), a condition known as “vitamin D deficiency” or “vitamin D deficiency syndrome”, are more than two times as likely to become schizophrenic than are people who maintain normal/healthy levels of the hormone/nutrient. The exact figure is 2.16 times more likely for those whose levels are inadequate relative to those whose are.

While co-author Dr. Ahmad Esmaillzadeh expressed hope that his team’s findings “might help psychiatrists in the healing process of patients with schizophrenia,” he cautioned against jumping to any conclusions with regard to the role (if any) vitamin D supplements will play in the prevention and treatment of this mentally trying condition.

“Controlled clinical trials are needed to confirm the effects of vitamin D supplementation,” Esmaillzadeh added.

Vitamin D3 Can Help Combat Inflammation

Vitamin D3 May Help Reduce Inflammation

By: Pamela Egan, MN, FNP

At the root of many, many chronic diseases and illnesses such as heart disease, high blood pressure, diabetes, cancer, arthritis, etc., is inflammation. If one can keep inflammation at bay, that person has successfully won half of the aging battle.

Vitamin D SunlightResearch shows you can drastically reduce your risk of cancer and countless other chronic diseases by getting safe sun exposure, or taking a high quality Vitamin D3 (cholecalciferol) supplement. Vitamin D3 deficiency has been associated with Fibromyalgia, Chronic Fatigue Syndrome, Diabetes, Colon Cancer, Obesity, High Blood Pressure, Heart Disease, Auto-Immune Disease, Neuro-degenerative Diseases including Parkinson’s, Alzheimer’s, Multiple Sclerosis and Lou Gehrig’s Disease, Osteoporosis, Depression, and also Breast Cancer.

Personally, I can always tell when my D3 levels falls lower than 60 because my feet get achy. However, this occurrence is rare as I make a point of regularly obtaining the nutrient through a variety of Vitamin D3 Sources.

Sun, Vitamin D and Inflammation

New data on nutrition and heart disease presented at a recent symposium and published in the July issue of the American Journal of the Medical Sciences shows that low vitamin D levels are a common problem affecting numerous health conditions, including high blood pressure, heart failure and ischemic heart disease.

I have many patients with auto-immune disease including Rheumatoid Arthritis and Lupus who are off of their medications including steroids and methotrexate with vitamin D3 10,000iu/day plus a course of prescription strength probiotics such as VSL-3VSL #3.  Many patients with hypertension are managed with Vitamin D3 5000 iu twice a day + Magnesium Glycinate 100mg twice a day.

High-quality vitamin d3 supplements are available at EGAN Wellness Clinic, the clinic’s online supplement shop and other providers of high-end nutritional supplements. It is important to actually purchase a high-quality supplement as opposed to grocery store and pharmacy brands, which are not anywhere near equal to the vitamin D3 made by companies like Douglas Laboratories, EGAN Wellness / EGAN Nutrition or a BioTech. The Vitamin D3 Blog provides this information for those who may be better off taking such a supplement (as opposed to receiving a flu vaccine) but don’t know where to obtain one that will achieve the desired results.
