Micronutrients and Infection with COVID-19: A Critical Mini-Review

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has been the cause of a global pandemic. Given the impact of nutritional status upon immune function, it is crucial to understand the relationship between micronutrient intake and severity of the disease. This mini-review aimed to summarize the known associations between specific micronutrients (vitamin A, D, E, C and zinc, selenium and magnesium) and the health of coronavirus-infected patients. Low serum levels of these micronutrients are associated with the incidence and severity of SARS-CoV-2. However, further studies are needed to evaluate the outcomes of supplementation with these nutrients.
