It's proactive, not reactive treatment for a disease. It's part of being healthy in the first place, which prevents developing severe COVID, cancer, heart disease, respiratory infection, stroke, diabetes, and death. It's like a car, you give it oil and maintenance to prevent engine damage, you don't give it oil to fix engine damage. Acting like binging on Vitamin D is supposed to suddenly cure any of those diseases is a complete misunderstanding how all this works. You can greatly reduce your likelihood of severe COVID and 100 other serious/fatal diseases through simple lifestyle changes, but they're not cures for those diseases. And fixing vitamin D deficiency shouldn't mean you take more pills, it should mean you get more exercise out in the Sun. Also, if vitamin D deficiency is an underlying cause of severe COVID, that would explain the enormous racial inequality for hospitalization and deaths rates. All these things are linked to the amount of melanin in one's skin. The hospitalization and death rates for COVID are double for people with Native American and African blood, and both groups have much higher rates of Vitamin D deficiency. https://www.cdc.gov/coronavirus/2019-ncov/covid-data/investigations-discovery/hospitalization-death-by-race-ethnicity.html https://www.cdc.gov/coronavirus/2019-ncov/covid-data/investi... https://www.cdc.gov/nutritionreport/pdf/Second%20Nutrition%20Report%20Vitamin%20D%20Factsheet.pdf https://www.cdc.gov/nutritionreport/pdf/Second%20Nutrition%2...

Right, but the GP-linked study disagrees with your assertion: “ We now have results for over 1500 RCTs on Vitamin D supplementation. Some of the largest and most significant trials are listed and summarized at the end of this article. When tested on its ability to prevent disease, Vitamin D has failed to live up to expectations." So no, it does not seem to work

  The 1500 RCT's are actually only 31 studies from what I can see. Those studies are do not all overlap either, they are all over the spectrum (D3 and flu, D3 and mortality, D3 and having children with Asthma). While good sources for specifics, there is a lot of wiggle room for follow up in some of these spaces where the results amount to a single study. I think the summaries speak for themselves: > "Vitamin D ... ... did reduce cancer death by 16%" > "Vitamin D did not reduce the risk of cancer" Seems like more research is needed here in these specific areas along with what exact version of D3 we are talking about (they are not all manufactured or extracted the same) and if supporting nutrients/lifestyles effect anything. I think the article just makes the good point that D3 isn't the magic bullet to any and all sickness without really being able to specify with a high level of certainly what it does help with.

    Part of the issue is that many vitamin and other health indicators are highly correlated with other things like income status, race, and other significant conflating factors. D3 also is related to being outside , which would influence the means of infection: lower initial viral load changes outcome.

  Actually yes, it does seem to work at least to a limited extent. Maybe do a little more research instead of relying on a single study. https://vitamin-d-covid.shotwell.ca/ https://vitamin-d-covid.shotwell.ca/
