Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases since 1984, appeared in an Instagram Live interview with actress Jennifer Garner, and claimed that he is "taking vitamin D supplements" to help prevent COVID-19, and suggested "a gram" of vitamin C "would be fine" to help prevent the disease.

In a wide ranging discussion where Fauci dictated how children must be forced to wear masks and socially isolate in school, what sports must shut down, who will be allowed to get a vaccine first, and what can be done to help prevent the spread of COVID-19 on a personal level.

Specifically, Fauci suggested vitamin C and D supplements to maintain a healthy immune system and help fend off the virus, especially if an individual is already deficient in vitamin D. He also said that he takes vitamin D supplements with COVID-19 prevention in mind, as he is typically deficient.
