Given the results of Neale’s large-scale study and the modest benefits found in Martineau’s latest meta-analysis, it seems unlikely that vitamin D will prove to be a critical ingredient in fending off COVID-19 or modulating its severity. But these and other new trials may find it is useful in certain doses for certain populations. As Neale points out, “there is data that is suggestive” and enough smoke to indicate that you don’t want to be vitamin-D-deficient in a pandemic.
Our bodies aren't so simple. It's quite possible that Vitamin D along with some other factor not yet identified would be protective. Of course, the best way to kill any research into that is to get Trump to endorse it.
ReplyDelete"Data that is suggestive" is always the last refuge when large randomized trials fail. Too many largescale controlled Vitamin D studies have failed at this point for all sorts of ailments. Avoid vitamin *deficiency* if you can, but the thinking that imbibing massive quantities of various vitamin supplementations will make a difference to the average person is badly flawed.
