(WSYR-TV) -- If you’ve had the flu this winter, you may have been tempted by supplements that claim to fight the flu. Don’t be.
U.S. health regulators have sent letters to nine Internet distributors of dietary supplements warning them against making false claims about their products' ability to fight the flu.
The U.S. Food and Drug Administration posted the letters on its website late Thursday in an effort to steer consumers away from a variety of herbal products that the distributors claim reduce the duration or severity of the flu.
"There are no over-the-counter products that shorten the duration or severity of the flu," Gary Coody, FDA's national health fraud coordinator, said in an interview.
The warning covers products including Resveratrol, Garlic, Echinacea, Elderberry, Ashwagandha and Astragalus Immune System Support.
