People are doing victory laps on stuff that really isn't proven. The study says there's a correlation That's it Somebody told me just before I got on here, so it's just something I saw on Twitter Maybe if there's a doctor here you can confirm or debunk this. It seems to me that if you did a hundred randomized controlled trials and every one of them confirmed that vitamin D is highly correlated with good outcomes is Still still it would tell you nothing about whether you should take more vitamin D. There are two hypotheses One hypothesis is that people in poor health have bad outcomes and people in bad health have low vitamin D.
