The proper claim is that raising people from deficient ( 30ng/ml ideally) should improve outcomes. Sometimes looking at a subset of those who started deficient is good enough to fi…

Nonesense. It's well established that dietary D3 (or D2, but D3 is better) clearly incleases 25(OH)D serum levels. It is that serum biomarker whose deficiency (levels below 20ng/ml…

The academic paper this story is based on is here: https://nature.com/articles/s43587-024-00793-y Despite the linked story title only mentioning omega3, the paper was about 3 inter…

No, ample evidence shows that vitamin D (or vitamin D deficiency at least) is causally related to multiple diseases. The evidence is pretty overwhelming. Eg here's a just published…

I put extended analysis of the results & caveats of what it means (correlation vs causation, etc.) on Twitter: https://twitter.com/KarlPfleger/status/1557814485070409728

I've collected the results from all 4 papers including the links to all 4 in a Google spreadsheet for easily lining up the results for each stage of Covid: https://docs.google.com/…

4 big systematic meta-analyses since Dec'21. Consistent results from all 4: Low D levels or not supplementing D has 1.5x-3x worse Covid risk at all stages (infection to mortality).…

Some critical responses to this new study are starting to accumulate: Dr. Peter Attia's takedown: https://peterattiamd.com/vitamin-d-nejm-study/ Dr. Ronald Hoffman: https://drhoffm…

One reason getting these from the evolved route may be better is because feedback mechanisms stop making the beneficial substance when the body has enough, which may not happen via…

I thought this piece spent too much time arguing about the wrong things (such as evolutionary stuff). I added 3 comments on what I think are the most important points with links to…

Just how much lower it would get cannot be discerned from available data yet. It is very hard to believe from current data that it would go all the way to zero and also very hard t…

Did you read the open letter (original link of thread)? There is an entire paragraph and footnote with 2 refs talking about the problem with the current government guidelines.

The site itself was set up (by me) just to host this open letter, just as the site masks4all.co was set up to host the similar open letter that happened for masks in the spring. Th…

This has been a big problem. Some people labeled science on vitamin D & covid19 as misinformation, lumping vitamin D in with things that have little to no evidence even when the vi…

The FLCCC has been pushing Ivermectin, but I am not aware of an open letter analogous to this one or the similar one for masks that is signed by 100+ doctors & scientists. I have n…

Subtitle: "We can't wait for perfect evidence" Op-ed by former surgeon general plus 2 other MDs.

185 experts. Over 100 medical doctors. Roughly 100 professors, including many of the most respected vitamin D experts in the world---check out the list of names and qualifications …

Terrible piece. First off, the majority of people with D levels of ~80ng/ml are fine, even quite healthy. Her problem was too much calcium, which is related but they (at least not …

Some point the figure at big pharma. I've no evidence of any foul play, but the pharma industry would lose money if a large fraction of their revenue comes from drugs to treat cond…

For months I updated my review of evidence that low D worsens C19. Is the tide starting to turn? (As it did for masks.) Hopeful signs lately. And time to go back to other things. S…

Correction (sorry, copy/paste error): The Mendelian randomization paper was by Kohlmeier. De Smet was one of the other studies.
