One of my friends was talking about Vitamin D and other things that help absorption of vitamin D
And was saying some doctor tested patients with Covid 19 for their D levels and all that tested positive were deficient in levels of D.
Interesting and with some google searching it leads to just more information and another theory.
I wonder if there is a written study that people that have the Positive Covid 19 test results that have no symptoms have high or normal D levels.
