As pointed out by Scataphagos in another recent thread, there is a lot of evidence that high vitamin D levels are protective against Covid. A new study makes the bold suggestion that deaths might be reduced to nearly zero if everyone took enough vitamin D3 to achieve a blood level of > 50 ng/mL. My understanding is that this would typically require supplementing with 2,000 - 4,000 IU of vitamin D3 per day. I've been taking 5,000 IU per day for some time, primarily because I had cancer several years ago and want to reduce the chance of a recurrence. --------- COVID-19 Mortality Risk Correlates Inversely with Vitamin D3 Status, and a Mortality Rate Close to Zero Could Theoretically Be Achieved at 50 ng/mL 25(OH)D3: Results of a Systematic Review and Meta-Analysis Lorenz Borsche , Bernd Glauner , Julian von Mendel Background: Much research shows that blood calcidiol (25(OH)D3) levels correlate strongly with SARS-CoV-2 infection severity. There is open discussion regarding whether low D3 is caused by the infection or if deficiency negatively affects immune defense. The aim of this study was to collect further evidence on this topic. Methods: Systematic literature search was performed to identify retrospective cohort as well as clinical studies on COVID-19 mortality rates versus D3 blood levels. Mortality rates from clinical studies were corrected for age, sex, and diabetes. Data were analyzed using correlation and linear regression. Results: One population study and seven clinical studies were identified, which reported D3 blood levels preinfection or on the day of hospital admission. The two independent datasets showed a negative Pearson correlation of D3 levels and mortality risk (r(17) = -0.4154, p = 0.0770/r(13) = -0.4886, p = 0.0646). For the combined data, median (IQR) D3 levels were 23.2 ng/mL (17.4-26.8), and a significant Pearson correlation was observed (r(32) = -0.3989, p = 0.0194). Regression suggested a theoretical point of zero mortality at approximately 50 ng/mL D3. Conclusions: The datasets provide strong evidence that low D3 is a predictor rather than just a side effect of the infection. Despite ongoing vaccinations, we recommend raising serum 25(OH)D levels to above 50 ng/mL to prevent or mitigate new outbreaks due to escape mutations or decreasing antibody activity.

99.9% of humanity will NOT understand this. All they care is present moment, comfort, luxuries, food esp at the cost of others. Looots of toxic artificial FOOD. Yea.... Humans will talk about bitcoin, dogecoin, shiba inu, latest video games, latest netflix crap, share photos of their meals, of their botox, of their tattoos. They will write 66666666 words articles about iphones and why iphones are 1.4% better than Samsungs. And test for 50 hours why this smartphone is 9% faster in games vs others. Humans will spend 66 hours choosing a hotel for holidays only to sit at the pool with chloride water. Pretty please, with cherry on top. Humanity is beyond hope. Insanely stupid crazy cult of its own dumb weapons of mass suffering.
Dr. John Campbell, UK physician, has a couple of videos on "Vitamin D and mortality". Data shows mortality for ALL disease is reduced when serum Vitamin D is ~ 40 ng/ml and continues to decrease to even >100ng/ml.... and is especially true for those who have any kind of heart condition. (125ng/ml is considered by some to the "threshold of toxicity") IOW... "Proper levels of Vitamin D in your blood is important to your health" FWIW...
Is it even valid to do regression on the concentration of a substance in the body to some point that isn't measured? I mean if you did a study of iron deficient people you would find that with higher and higher doses of iron their health improved. Do a regression to higher doses beyond what was studied and you would decide that more always equals better, until you actually test at those high levels and realize it kills people!

I won't post all the studies- people can do their googling- but blacks/African Americans are majorly subject to Vitamin D deficiency/insufficiency because the high level of melanin in their skin filters out the rays needed to produce vitamin d in the skin. I don't want to offend any woke-sters but a high number of African-Americans are descended from people from Africa where the need to filter out uva/uvb is greater than in Detroit in January. At the same time, the medical community highlights at length how covid hits the black community harder and spins off elaborate theories of disparities in income, health care etc. That's all fine, that's how we roll in America these days. We go for the social injustice angle first and work that to death until it doesn't work anymore. But those who actually care about public health, might actually scratch their heads a bit more and connect some of the dots between low D level populations and covid risks. Just as a reminder here for those new to the topic: don't be a cheapskate, and decide that you want to start taking vitamin d so you run over to walmart and get the cheapest bottle that says vitamin d on it. That is vitamin D2. You don't want that and don't even bother unless you are vegan or something and got something special going on. You want D3. Also, if you are serious about things, vitamin d is fat-soluble so take it with some fat, or a little olive oil or the like. Technically, vitamin d is a hormone and not a vitamin but whatever. Also, there is no way of knowing what your level is without a blood test. You can do your little reading and calculations and conclude that 1000 iu's or 2000 or 600 a day per some medical standard is sufficient but that is bullshiite. Vitamin d levels are notoriously difficult to raise and you could take thousands per day and not move the needle. You don't know unless you test. The other thing to consider is that we are going into winter but if you got some time at the beach this summer your liver is still storing lots of d for a couple more months so your blood levels might be good now. Come February or so they might be a disaster though. If you live in the north, they usually are. So it is good to know what your blood levels are in late winter to know what your worst case is. Blood test is - I dunno- about 50 bucks or so. If you do it without a doctors visit and all of that.
I think yer a little-off on that. Vitamin D being fat-soluble doesn't mean exclusively that you need to take it with fatty foods. It means that it collects in the fat cells of the body. As the vitamin passes through the intestinal tract, it is absorbed down the 4,000,000 miles of the intestines, which are lined with fat. As such, it can accumulate in the body, and too much of it can lead to toxicity. On this I have experience. A couple of years ago, I was shown to have a slight Vitamin D deficiency after a blood test. I suppose because I rarely drink milk, and have an aversion to the sun. The doc prescribed a banger of a scrip, something like 5,000 IUs for 7 days. Next blood test on follow up showed normal levels. We did that twice over a year. I am trying REAL hard to remember what it said on the Rx bottle...D2 or D3, and simply cannot. I guess you could consider that a booster dose for Vitamin D deficiency. But I would not rely on D alone to help prevent a covid infection.
A teaspoon of cod liver oil a week should do you right. Get the kind that doesn't filter down the vitamin A and D.
