Myth: Vitamin D supplements can prevent or even treat COVID-19

These myths began when some research studies showed higher rates of death and disease from COVID-19 in places where people have lower vitamin D levels. But — these studies do not prove that low vitamin D levels are the cause of disease and death. In fact, there is no proof that taking a vitamin D supplement can prevent or treat COVID-19. The danger of believing this myth is that people could take a vitamin D supplement and have a false sense of protection against the infection.
