Heather Heying on Vitamin D for COVID-19
The Chloroquine Wars Part LXXXIII
"Acquire the art of detachment, the virtue of method, and the quality of thoroughness, but above all the grace of humility." -William Osler
I won't claim to have a lot of great virtues. Most of them revolve around animals and curriculum development. I have excellent taste in comedy (by my own humble standards). I love beagles and concise thoroughness.
I have several pages of notes on Vitamin D, and planned to read it through again, and write a summary here for you readers. But Heather Heying has done that job well. Thoroughly well.
Verdict: There is very little reason not to maintain a good bioavailable supply of vitamin D, and that very likely helps---and likely to a substantial degree---fight off COVID-19.
I may still write on the subject, including the strange tale of how Canada's health bureaucrats let a technical error in a paper sandbag the recommended daily allowance for consumers, or how the UK stopped fortifying school lunches with vitamin D just a few years ago. But if you want a well-sourced article that lays out the case for vitamin D during the pandemic, go read what Heather wrote and bookmark it.
Then go get some sun if you haven't already today.
