    Anyone verifiably raise vit D levels transdermally?

    Outside of this forum, very few people online talk about using vitamin D by applying it on the skin, and just going through some posts on here it seems some people tried and failed at it. I was wondering if anyone can confirm by blood test they raised their levels using transdermal application...

    PTH - the connection of all stress hormones

    "When there is adequate calcium, vitamin D, and magnesium in the diet, PTH is kept to a minimum.

It used to be a problem mostly in women over 45 who were trying to get pregnant, however, it has now become a common finding even in 30+ year-old females. Estrogen is known to play a big role, and some studies have...

    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.

    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...

    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. 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

    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...

    Anti-A people, how do you respond to D?

    I've been researching the relationship of vitamin A and D. Before I give any of my own input I'd like to know how the people who benefit from vitamin A restriction feel on vitamin D supps or intentional sun bathing. Please include your history of pharmaceutical A use if applicable.

    VItamin D Megadose accident, what to do

    I thought the bottle dropper was in the vitamin D supplement, but it wasn't, so I dumped about a quarter of the Carlson vitamin D on my belly button by mistake. I reacted immediately, rubbed it off, and took a quick shower with a lot of soap to rub it off fully. I know the vitamin topically...

    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)...

    Vitamin D prevents cortisol-induced depression and...inflammation

    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...
