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 studies demonstrating that vitamin D … Read more

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 should be applicable to the other gender as … Read more

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). As per the study below, vitamin D joins niacinamide … Read more

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 vitamin D3 (cholecalciferol), in direct opposition to the known catabolic effects … Read more

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 high-dose vitamin D may ameliorate COVID-19 … Read more

Vitamin D may treat (opioid) “addiction”

Interesting article, which corroborated the role of vitamin D as an anti-stress hormone. As vitamin D is an actual steroid, it is expected to have a role as neurosteroid as well, and as such influence behavior and habits, including pathological ones such as “addiction”. Why do I put “addiction” in quotes? Mostly because the totality … Read more

High PTH, low vitamin D implicated in bipolar disorder (BD)

A great study highlighting once again the importance of calcium, vitamin D and especially the pro-inflammatory parathyroid hormone (PTH) for mental health. While there are many studies (both observational and intervention ones) examining the role of vitamin D in mental health, this is one of the very few looking into the role of PTH. It … Read more

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 cortisol injections, however the effectiveness … Read more

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, it demonstrated decrease in lean mass in the deficient … Read more
