Updated NHS advice on vitamin D from [1]

“ Coronavirus update Consider taking 10 micrograms of vitamin D a day to keep your bones and muscles healthy.

This is because you may not be getting enough vitamin D from sunlight if you’re indoors most of the day.

There have been some news reports about vitamin D reducing the risk of coronavirus. However, there is no evidence that this is the case.”

NHS may say 'no evidence' - but it seems likely what they mean is that nobody has done a vitamin D-coronavirus trial. So it isn't that there is no evidence but rather the evidence is not overwhelming.

"No evidence" makes it sound like there is actually no evidence. There is evidence - it just got linked in the two comments that make up the root of this thread.

> We found no evidence that (25(OH)D) explains susceptibility to COVID-19 infection, either overall or between ethnic groups.

It's worth noting that this study only looked at risk of infection, not the severity of infection. The grandparent comment was about severity/death.
