Researcher: Vitamin D can help prevent contracting COVID-19 - KIRO Seattle

Michael Holick, Ph.D., MD, professor of medicine, physiology, biophysics and molecular medicine, found that vitamin D can boost the immune system to prevent the infection or at least lessen the impact of the virus.

“What we observed is if you’re vitamin D deficient, you have a 54% chance of having a higher risk of acquiring this infection compared to patients who are vitamin D sufficient,” said Holick.

But if you looked closer, the study found patients with lower vitamin D levels had a 12.5% rate of infection, and those with higher vitamin D levels had an infection rate of 5.9%, which is less than half.

Holick said having enough vitamin D will help by “reducing risk of acquiring the infection and reducing the complications and death associated with it.”.
