Patients with Vitamin D Deficiency Are Twice as Likely to Test Positive for COVID-19

September 18, 2020

As health experts continue to learn about COVID-19 infections and who may be at higher risk, a recent study focused on vitamin D levels.

The Sept. 3 JAMA study found that patients with vitamin D deficiency were 1.77 times more likely to test positive for the virus than patients with sufficient vitamin D. 

Vitamin D is important for the immune system and long before the pandemic, supplements for this vitamin had been known to help lower the risk of viral respiratory tract infections. 

A whopping one-half of the U.S. population is vitamin D deficient, with higher rates among Black and Hispanic populations, as well as individuals who live in areas where it is difficult to obtain the needed amount of sun exposure.
