MYTH: Quercetin, essential oils and other supplements can protect you from the coronavirus or treat COVID-19.


Taking quercetin, zinc, or vitamin D and other nutritional supplements cannot prevent or treat coronavirus infection or COVID-19. The same is true of essential oils — they are not effective to prevent coronavirus disease. The best ways to stay safe from COVID-19 are getting vaccinated, wearing a mask (especially in crowded or indoor settings), keeping your hands clean and practicing physical distancing.
