Researchers have wondered whether vitamin D may help people avoid SARS-CoV-2 infections and mitigate the effects of COVID-19.
A randomized, double-blind, placebo-controlled clinical trial seeks to test vitamin D’s usefulness in combatting the disease.
The study finds high doses of vitamin D have no effect on key COVID-19 outcomes in particularly ill hospitalized patients.
Further research is needed to investigate whether a deficiency of vitamin D is associated with more severe cases of COVID-19.
