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
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
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
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
Danny and I already discussed this topic on a recent podcast, but I decided to post the studies anyways, considering how important the topic is. While progesterone and testosterone are the most well-known differentiating factors in humans, the role of vitamin D has gone largely unnoticed. The studies below demonstrate that vitamin D is a … Read more
A great study for a number of reasons. First, it discussed openly that in animal research circles cortisol administration is considered an official and reliable method of causing major depression. As the article states, for some reason human medical circles have been unwilling to accept the stress-depression causal link and continue to argue that stress … Read more
In a recent post of mine I discussed the effects of cortisol on various aminotransferases (especially TAT), their role as biomarkers of catabolism, and how inhibitors of said aminotransferases have a potent anti-catabolic / anabolic effects. In that same post, I also described how cortisol (a catabolic steroid) is, naturally, a potent inducer of those … Read more
A very interesting study, not only because of its obvious social implications but also because it confirms the anabolic effects of the vitamin D/K combination, as well as the likely androgenic effects of vitamin D. I could not help but pronounce the D/K combo in my head as “dee-k” 🙂 Another interesting finding of the … Read more
A neat study, albeit lasting much longer (about 1.5 years) than most other intervention studied with vitamin D. What makes this study particularly interesting is that it only used high doses vitamin D (60,000 IU once weekly) initially until blood levels rose into the normal range. It did not seek to achieve a specific target … Read more
A great new study demonstrating the crucial role of vitamin D in maintaining proper immune function. The study demonstrates that maintaining normal levels of vitamin D is strongly protective against gut infections by Salmonella-type bacteria. Interestingly, the authors claim that vitamin D is likely to provide protection against inflammatory bowel disease (IBD) conditions such as … Read more
