Can vitamin C and zinc help you fight off Covid-19?
No, not even at high doses, according to the first randomized clinical trial to test the two supplements under medical supervision.
Despite the popular use of vitamin C and zinc to fight off or lessen the severity of viral colds and flu, the new study, published Friday in JAMA Network Open, found the two supplements were of no benefit to people isolating at home with Covid-19.
In fact, the findings were so unimpressive that the study was stopped early.
"Unfortunately, these 2 supplements failed to live up to their hype," wrote Dr. Erin Michos of John Hopkins and Houston Methodist's Dr. Miguel Cainzos-Achirica, in an accompanying editorial.
