There's Only Weak Evidence For Vitamin-D As a COVID-19 Preventative—But Scientists Are Trying to Learn More

 To protect himself from COVID-19, Dr. Anthony Fauci has long said he’s skipping hugs and handshakes, wearing a mask, and staying off of planes. Last week, he acknowledged adding another step to protect his health: taking supplements of vitamin-D.

 However, while spurious claims that vitamin-D can prevent or treat COVID-19 have proliferated online, including some recommending potentially dangerous doses, it’s important to point out that Fauci wasn’t talking about vitamin-D helping with COVID-19 in particular. Instead, he was speaking more broadly about vitamin-D’s importance in caring for our immune system. Vitamin-D is important for our musculoskeletal health and immune function, but it’s far from clear whether boosting our intake can ward off or treat COVID-19 in particular. At this point, the National Institutes of Health says there isn’t enough evidence to recommend using vitamin-D to prevent or treat COVID-19, but it also says there isn’t enough evidence to recommend against it, either.
