    Muscles starve/waste in the absence of vitamin D

    As turns out, yet again, vitamin D is far from being the simple "bone vitamin" as most TV/online commercials would have us believe. It is actually a (seco)steroid and has already been implicated in a host of metabolic and immune process affecting virtually every disease. Recently, I posted a few...

    Oral vitamin D3 may treat steroid-driven hair loss

    A very interesting study, which demonstrates that a relatively low (5,000 IU) oral daily dose of vitamin D3 for 6 months, may be able to treat gender-specific (driven by steroids) hair loss. Now, the study participants were all female, with female-pattern hair loss (FPHL), however the findings...

    Vitamin D may prevent/delay Type I diabetes

    Vitamin D seems to be trying to take aspirin's crown as a universal drug away. The study below is the latest evidence that this remarkable nutrient may have therapeutic effects in conditions that most doctors consider completely unrelated outside of vitamin D's realm (e.g. calcium absorption)...

    Vitamin D3 anabolic, calcitriol catabolic for muscle/thymus

    Several great studies, which will probably do little to calm down the controversy that seems to be brewing lately in the blogosphere over whether supplementing with vitamin D3 is beneficial or not. Namely, the last study below demonstrated direct muscle-anabolic effects from supplementation with...

    Vitamins D and E - the Taliban in the COVID-19 war

    Despite the massive censorship all over the Internet, there have been plenty of articles and studies on vitamin D and its role in COVID-19. Several studies reported that at least 9 in 10 of hospitalized patients have severe vitamin D deficiency. In addition, a few small studies demonstrated that...

    Avoiding sunlight increases colon cancer risk

    Some time ago I posted about avoiding sunlight being as bad for systemic health as smoking a pack of cigarettes a day. The study below corroborates that view, but with a focus on colon cancer risk and vitamin D. Namely, avoiding sunlight exposure results in much lower vitamin D, which is...

    Vitamin D (topical) safe and effective for removing scars

    A neat human study, which demonstrates that topical treatment with vitamin D may treat even large scars that have been present on the skin for years. Many people have such scars as a result of surgery, trauma, chemical/heat burns, radiation, etc. As the study says, the typical treatment is with...

    Vitamin D deficiency impairs muscles by lowering energy production

    Perhaps this study below will put some of the arguments against vitamin D supplementation to rest. It demonstrated up to 40% reduction of energy production in the muscles of animals deficient in vitamin D, in spite of unchanged number/size/density of mitochondria inside the cells. In addition...

While progesterone and testosterone are the most well-known differentiating factors in humans, the role of vitamin D has gone largely unnoticed. The...

    Nine out of ten COVID-19 deaths may be due to vitamin D deficiency
