Welp. I don't think it's gonna make the difference if I get COVID-19, but I did order some Vitamin D supplements. I live in a low-sunlight area, work indoors, and don't drink a lot of milk. 75% of people in my region are Vitamin D deficient. I can put two and two together.

My guess: It might not make _the_ difference whether you _get_ it, but it's not at all unlikely (given all the evidence that has accumulated so far & extrapolation from experience w/ other viral respiratory infections) that it will influence disease severity significantly.

There's enough evidence for vitamin D being beneficial that it's certainly not likely to hurt anything and is probably a good idea.
