Vitamin D sales are up. But experts still don’t know whether it can prevent or treat covid
The Washington Post
People with vitamin D deficiency are often dealing with other health factors that could affect their chances of contracting the coronavirus and falling seriously ill, said Natasha Chida, an infectious-disease expert and assistant professor of medicine at Johns Hopkins University. Chida added that vitamin D levels typically drop when people are sick with diseases such as covid-19.
“Unless you take into account all those factors and separate all those out and look at just vitamin D, . . . it’s really hard to make any inferences about what vitamin D is doing here,” she said.
There is also no solid evidence that vitamin D supplementation will lower the risk of becoming infected or developing a serious case of covid-19.
