Exploring the Links Between Coronavirus and Vitamin D
In the past decade, studies have found that taking vitamin D can lower the odds of developing respiratory infections like the cold and the flu, especially among people who have documented deficiencies. Now scientists are trying to find out whether vitamin D might also help protect against Covid-19.
Some scientists believe that people with vitamin D deficiencies have weak or abnormal immune responses that make them more susceptible to developing Covid-19 and experiencing severe symptoms. The notion that vitamin D levels could influence the risk of Covid-19 has sparked debate among experts and prompted researchers at Harvard and other universities to start randomized trials examining whether there is a link.
But so far, most of the evidence for the claim comes from observational studies that do not prove causation. And experts are urging people to be cautious about gobbling down high …continued .
