No. Vitamin and mineral supplements cannot cure COVID-19. WHO states that micronutrients, such as vitamins D and C and zinc, are critical for a well-functioning immune system and play a vital role in promoting health and nutritional well-being. There is currently no guidance on the use of micronutrient supplements as a treatment of COVID-19. WHO is coordinating efforts to develop and evaluate medicines to treat COVID-19. (**Always check with your doctor and know if your body is deficient and requiring additional dosages. Some vitamins may interact with some medications.)
