Coronavirus and Vitamin D: Is there a Connection?

The short answer to that question is: quite possibly.

In an interview, Dr. JoAnn Manson, a professor of medicine at Harvard, suggests that adequate levels of vitamin D in the body may, indeed, help prevent you from both getting infected with the coronavirus in the first place and reducing its severity if you do. Vitamin D enhances immune function and decreases inflammation, perhaps particularly in the respiratory system. Dr Manson cites a study showing that there was increased prevalence of coronovirus in people who were deficient in vitamin D and that these people were also more likely to have serious complications.

How to get more vitamin D? Sunlight is a great source of vitamin D, but it’s also a causative agent of skin cancer, so be careful. The food sources Dr. Manson recommends are fortified dairy and cereal products (check the labels), along with fatty fish (like salmon), and sun-dried mushrooms (sun-dried mushrooms? Never heard of them – I’m going to do some investigation and get back to you).

If you want to take a vitamin D supplement, Dr. Manson has says “The recommended dietary allowance of vitamin D is 600-800 IU/daily, but during this period, a multivitamin or supplement containing 1000-2000 IU/daily of vitamin D would be reasonable.”

So now we know. It looks to me like a lovely day for grilling salmon…
