Can vitamin C and zinc help you fight off Covid-19?
No, not even at high doses, according to a 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 colds and flu, the new study, published 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.
Doctors wrote, “Unfortunately, these 2 supplements failed to live up to their hype.”
The clinical trial gave high doses of each supplement alone and in combination to one of three groups of 214 adults who were recovering at home. A fourth group got standard care, such as rest, hydration and fever-reducing medications, but no supplements.
However, scientists continue to explore the use of vitamins and supplements in the treatment of Covid-19.
