Yet when it comes to articles that suggest links between Vitamin D and COVID severity, they may not even be studies, but rarely will the top comment be the one calling out the caveats. It's an interesting reflection of how even HN's fairly simple mechanism of ranking comments promotes groupthink. FWIW, I take daily Vitamin D tablets because when COVID was fairly new my doctor suggested there might be a link, and gave me a prescription that would help maintain my vitamin D levels.
