Abstract
Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which produces COVID-19, is the most deadly coronavirus ever identified. Essential treatments and nutrition are crucial for improving the immune system against viral infection. As studies recommended checking the nutritional state of COVID-19-infected individuals before treatment, we aimed to review the therapeutic, preventive, and immune-boosting effects of some minerals and vitamins on COVID-19. This review emphasizes the possible therapeutic, preventive, and immune-boosting effects of some minerals such as zinc, selenium, iron, calcium, phosphorus, potassium, and magnesium and vitamins C, D, and E on COVID-19 patients. Regarding the evidence that shows the preventive effects of vitamins and minerals on serious COVID-19, it seems that clinicians have to consider these factors precisely.
