Meta analysis showing vitamin D deficiency associated with higher risk of COVID-19, worse severity, and higher mortality.
Supplementation with vitamin D reduced the risk of severe cases and mortality.
Currently there are 82 vitamin D for COVID-19 studies, showing 37% [25‑47%] lower mortality, 32% [4‑53%] lower ventilation, 50% [27‑65%] lower ICU admission, 20% [9‑29%] lower hospitalization, and 12% [2‑21%] lower cases.
