Research shows that people with higher vitamin D blood levels have lower rates of COVID-19 infections and lower risk of contracting severe cases that could lead to hospitalization or death.
Dr. Joan Lappe, an associate dean for research and a professor in the College of Nursing at Creighton University, Nebraska, said cells in the body need an adequate amount of vitamin D to function efficiently and boost one’s immune system. Exposure to sunlight is the primary source of vitamin D.
“Here in Nebraska in the winter, most people likely have low levels of vitamin D,” she said. “The easiest way to take care of that is to take vitamin D supplementation.”
Dr. Lappe recommends taking at least 2,000 international units of vitamin D a day during the winter season. She said the elderly, home-bound individuals, and people who are obese are more vulnerable to vitamin D deficiency.
