People with a vitamin D deficiency are 54% more likely to test positive for SARS-CoV-2, with Black and Hispanic communities most at risk, according to a new study.
"We evaluated more than 190,000 blood samples from patients of all ethnicities and ages infected with COVID in all 50 states," said Dr. Michael Holick, professor of medicine, physiology and biophysics at Boston University School of Medicine. "We observed that the higher that the patient's blood level of 25-hydroxyvitamin D was, up to 55 ng/mL [the] lower was their risk of being infected with the coronavirus."
Holick said his team found that "patients living in predominantly African-American and Hispanic zip codes were more likely to be Vitamin D deficient and have a higher risk of acquiring the infection."
"The higher your vitamin D status, lower was your risk (of contracting the coronavirus)," he said. "Vitamin D definitely improves your overall immunity to fight infections."
