Can magnesium protect me from the coronavirus?

No. No vitamin or supplement is known to protect against, prevent or cure COVID-19. The most important steps you can take are to avoid exposure to the virus according to CDC-recommended guidelines:

  • Wear a mask when out in public.
  • Wash your hands often with soap and water for at least 20 seconds.
  • Maintain social distancing and avoid close contact with others.
