Evidence from several clinical trials and pooled studies show that vitamin D supplementation lowers the severity of acute respiratory tract infections. Benefits of supplementation have been proven among patients of all ages, including people with pre-existing chronic conditions.
To reduce the risk of severe infection, the Institute for Functional Medicine recommended that people at risk of influenza and/or COVID-19 consider taking at least 5,000 IU/d of vitamin D3 for a few weeks to rapidly raise 25(OH)D concentrations. The goal should be to raise 25(OH)D concentrations to optimal levels between 50–80 ng/mL (125–200 nmol/L).
Please note, anybody can get infected with COVID-19 regardless of their vitamin D levels, however, severe symptoms seem more likely among people deficient in Vitamin D.
