Warning Letters Sent to Companies Selling Supplements Claiming to Treat Diabetes

The FDA has not evaluated these products for safety or effectiveness.

Warning letters were issued by the Food and Drug Administration (FDA) and the Federal Trade Commission to 10 companies for illegally selling dietary supplements claiming to cure, treat, mitigate, or prevent diabetes.

According to the FDA, products manufactured by the following companies should not be used for diabetes management as they have not been evaluated for safety or effectiveness:

Health care providers and consumers are encouraged to report adverse events related to these unapproved products to the FDA’s MedWatch Adverse Event Reporting program or the Safety Reporting Portal.

“Dietary supplements that make fraudulent claims to treat diabetes are unapproved new drugs that could potentially harm consumers who use these products instead of seeking safe and effective FDA-approved treatments,” said Cara Welch, PhD, Acting Director of the Office of Dietary Supplement Programs in the FDA’s Center for Food Safety and Applied Nutrition. “The FDA is committed to protecting US consumers from products and companies that make unlawful claims to treat or prevent diabetes, and we’ll continue to hold companies accountable by alerting the public about products that place consumers at risk.”

The FDA advises caution when purchasing dietary supplements online, especially those with claims that appear to be too good to be true.
