I thought we could start a thread about Vitamin D. There is a thread about Sunlight and Vitamin D that we can link into this thread. I wanted a more comprehensive place for a Vitamin D discussion.
I saw this study which is interesting. They found that Vitamin D taken during pregnancy boosts children’s bone health even at age seven.
The study tracks over a decent amount of time, which is nice.

@Cari can you approve this thread and post? Thank you 🙏🏻Here is another good study that Georgi shared: Vit D helped diabetes EVEN in obesity situations.
@Cari can you approve my post with a link?“Because of contaminants in supplements | seldom recommend the oral use of any of them, except aspirin, which can be dissolved in warm water to remove most of the additives. In the winter I use vitamin D, but only on my skin in an oil. Using a thyroid supplement temporarily might help to lower your estrogen.” -Ray Peat
Sep 23, 2There is a lot of data on Vitamin D. The most recent comorbidity that I have come across is how Vitamin D relates to hypertension. Interestingly I came across this after someone close to me was started on Statins with their other prescription stack. I was aware that CoQ10 was depleted from this drug and that Vitamin D was also depleted from lowering cholesterol. But a side effect of reduced vitamin D levels is atherosclerosis. I was unaware of this steroids role in calcium metabolism and escorting it to the correct areas. If one is “diagnosed” with hypertension, it would be good to look at the Vitamin D levels as well as K2 these seem to work synergistically together. I think that I would adjust my levels of these two first then look at calcium intake before any pharmaceutical options.
There are some people within the medical profession that do recognize the critical role that Vitamin D plays within the health of humans. I found it rather interesting how many conditions have a Vitamin D deficiency attached to them, not the least of them being both cancer and diabetes. Dr Campbell interviews Dr David Anderson. He mentions the importance of zinc but did not talk about the importance of magnesium in the process of Vitamin D’s metabolism.
I am going to reiterate a thought, perhaps a hypothesis. But what if the actual main driver for the benefits of vitamin D is not found purely in the hormone itself but from the light from which it was produced?
We know that sunlight has positive effects on the mitochondria. It has also been shown that sunlight can change the microbiome in positive ways.
Skin exposure to sunlight: a factor modulating the human gut microbiome composition
Background: The gut microbiome has been increasingly acknowledged as playing a pivotal role in human health. Therefore, a number of studies have focused on variables that impact its microbial structure and consequent functionality. A wide range of factors, such as diet, age, sex, life stage, behavior, ethnicity, and diseases have been considered, and strong links were set out. However, some aspects regarding the microbiome determinants are still under-explored. Discussion: Recently, Bosman et al. presented evidence that skin exposure to narrowband UVB light modulated the gut microbiome of a specific human cohort. This cohort presented an increase of biodiversity, Firmicutes and Proteobacteria, and a decrease of Bacteroidetes. Based on these findings, we revisited our data on a hunter-gatherer gut microbiome (Yanomami) and identified similarities in the gut microbiome of these two cohorts. Both presented a high abundance of Proteobacteria, which had been observed as a unique feature in the Yanomami gut microbiome, and based on Bosman et al study, could be associated with their natural sunlight exposure. Conclusion: In this commentary, we would like to point out that the human lifestyle concerning sunlight exposure should be considered as one force modulating the gut microbiome, highlighting, as proposed by Bosman et al, a novel skin-gut axis which is associated with health and disease.
Perhaps we are looking at this backwards. What if Vitamin D is actually a signature biomarker for getting an adequate level of exposure to sunlight? If we do not have enough light exposure we do not get enough Vitamin D.
Perhaps older people go further south for the winters because they have reached a point where they cannot produce adequate amounts of Vitamin D in the skin, so they move closer to the equator where there is more light year round? Endless summer if you will.
Yes @J.R.L the sun is so much more than just a simple vitamin and is as you said about light, the pineal gland, circadian rhythm, melatonin, and so many other things that I have been reading about. Comparing the sun to ingesting a vitamin D is like comparing raw milk to taking a calcium supplement. I personally would not swallow a D pill.
No doubt sun exposure is important, and is more than just Vitamin D (especially Red and Infrared light), but Vitamin D itself is a very useful vitamin/prohormone/nutrient. Beyond supplements, it can be found in foods like mushrooms, and also foods made from blood, like blood sausages. It was never gotten exclusively from sunlight, although that was and is a significant source.
Dr. Coimbra and the Coimbra Protocol has found benefits to those with so called “Autoimmune” conditions, by taking massive doses of Vitamin D, sometimes up to 300,000 IU per day. These are doses that could never be achieved by sun exposure alone, and has shown reversal of conditions like MS, Psoriasis, Lupus and Vitiligo.
Of course, the choice to supplement should be left up to the individual. I agree with Cari, that D and Sunlight are not the same, and neither are milk and Calcium supplements. But even Ray Peat told stories of people who benefitted from calcium supplementation, like the pitcher with fragile bones who ate a teaspoon of eggshells a day for six months, and didn’t have an issue with broken bones after that.
