Looks promising, but I would want to see a true double blinded RCT on a few thousand people before we say that Vitamin D is an effective treatment.
Also, there's going to be a confounding question based on this study: is it just Vitamin D, or is it Vitamin D in combination with HCQ / Azithromyacin?
That said, it probably wouldn't hurt you to supplement with Vitamin D this winter, even if it doesn't treat Covid.
- gojomo 6y agoIn combo with other observational studies correlating Vitamin-D-deficiencies with the worst Covid-19 outcomes, the case is growing. Vitamin-D in moderate amounts is pretty safe, so for those not already getting adequate sun exposure, it's a low-risk, high-potential-reward supplement.
- cameldrv 6y agoIt's difficult to imagine how the placebo effect could produce this result. Both arms of the trial were receiving HCQ and Azithromycin, so to the extent that there is a placebo effect, you'd think that adding a vitamin wouldn't change the result very much.
- woeirua 6y agoI’m not saying it’s a placebo effect. Instead there could be unknown interactions between Vitamin D and HCQ/Az that could be the causal effect.
