conflicting conclusions. Now, a study from researchers in Brazil provides a more robust answer to at least one key question: can vitamin D help prevent COVID-19 complications in particularly ill hospitalized patients?
According to the results, the answer appears to be no.The study found that high doses of vitamin D administered to hospital patients with moderate or severe COVID-19 did not affect the course of the disease.“In vitro studies or trials with animals had previously shown that in certain situations, vitamin D and its metabolites could have anti-inflammatory and antimicrobial effects, as well as modulating the immune response,” explains Rosa Pereira, principal investigator for the study.
