Can micronutrient (vitamin and mineral) supplements prevent COVID-19 in healthy individuals or cure it in those with COVID-19 disease?

No. There is currently no guidance on micronutrient supplementation for the prevention of COVID-19 in healthy individuals or for the treatment of COVID-19. Micronutrients are critical for a well-functioning immune system and play a vital role in promoting health and nutritional well-being. Wherever possible, micronutrient intakes should come from a nutritionally balanced and diverse diet, including from fruits, vegetables and animal source foods.
