Thereís a study out of Spain published the last week of August which confirms what observational studies have suggested - that vitamin D may play a huge role in controlling the severity of Covid. In the study, hospitalized patients were all given standard of care. 60 were also given vitamin d (a rapid acting form that raises vitamin D levels in a day instead of a week). Only 1 out of the 50 had to go to the ICU, and none died. Of 26 controls who didnít receive the vitamin D, half ended up in the ICU and 2 died.
Bottom line, a large dose of vitamin D right now might lessen the severity of disease. I would also add zinc lozenges, vitamin C, niacinamide and B12.
