Vitamin D is such a hot topic for its purported role in preventing or treating coronavirus infections that I seem to have written about it four previous times. These are here, here, here, and here.
Now, a group of 120 scientists has called on world governments to get their populations to increases vitamin D consumption to 2000 to 4000 units per day, five to ten times higher than current recommendations. Their letter is here.
This is especially interesting because nutrition and health societies in the UK advise quite the opposite: no change in the usual recommendation for vitamin D intake (400 units/day). Their report says (my emphasis):
- Do not offer a vitamin D supplement to people solely to prevent COVID-19, except as part of a clinical trial.
- Do not offer a vitamin D supplement to people solely to treat COVID-19, except as part of a clinical trial.
I’m always interested to see what ConscienHealth has to say about such things.
The passion of the vitamin D fan club is striking. However, neither passion nor speculation should be a substitute for facts. Right now, the facts tell us that the reason to take a vitamin D supplement is to protect our muscles and bones. Any thought that it will help with COVID-19 is speculation, and taking too much would be quite unwise.
My sentiments precisely.
