Having low vitamin D levels has been shown to be an independent risk factor for having symptomatic COVID-19 with respiratory distress that requires intensive care admission and results in increased mortality. However, boosting vitamin D levels in patients who are critically ill with COVID-19 has not been shown to shorten hospital stay, lower odds of intensive care unit admission, reduce the need for mechanical ventilation, or decrease the risk of dying. A study of more than 1.2 million people of European ancestry from 11 countries found that those with genetic variants that resulted in naturally higher levels of vitamin D did not have a lower risk for COVID-19 development, hospitalization, or severe disease. However, individuals who have low plasma vitamin D levels have been shown to be at higher risk for COVID-19 development and hospitalization.
