    Vitamin D deficiency impairs muscles by lowering energy production

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...

    Is There Something Wrong About How We Get Vitamin D From Sunlight? I Suspect We Do It In a Very Unnatural Way

    At noontime, when the sun's out in full force, where there's not even a shadow as the sun is directly above, I would go out and get my fill of sunshine and the vitamin D benefits of it. This is usually where the UV index is highest, and where I get the most vitamin D produced in the shortest...

    Vitamin D can force cancer cells to differentiate back into normal

    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.

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

    A remarkable claim in this study, but not really surprising to people who have been studying the vitamin D effects on the immune system. While the study was observational, as the authors explain, the correlation between vitamin D insufficiency and COVID-19 mortality was so high that the authors...

    Fasting ups estrogen & cortisol, decimates vitamin D, may cause diabetes

    A really interesting study, which will likely generate more than a few hateful emails for my Inbox :): Anyways, as the study demonstrates, fasting achieves these negative effects due to the elevated fatty acids working through PPAR activator PGC-1α, to activate both the estrogen receptor (ER)...

    For the past few months I've been taking an oral vitamin D supplement, and I'm sleeping better than I have since I was a kid. Some nights I don't wake up to pee, which is really significant for me, because typically I get up at least twice. I'm taking a 4000IU supplement on average three times...

    I’m Not Convinced Vitamin D Should Be Supplemented
