The Full Story

Some "weight loss" supplements can damage your health along with your wallet. And, they rarely help you lose weight. In recent years, many tainted weight loss products have been sold in the U.S. Hidden ingredients have included stimulants, antidepressants, diuretics, seizure medicines, and laxatives. This list includes prescription drugs, over-the-counter drugs, and drugs which are illegal to sell in the United States. Sibutramine is the most common drug found in contaminated weight loss supplements. Sibutramine is a stimulant and appetite suppressant. At one time, it was sold legally in the U.S. Then, a study showed that the risk was greater than the benefit: people taking sibutramine didn't lose a lot of weight, but they had an increased chance of having high blood pressure, fast heart rate, a heart attack, or a stroke. Sibutramine was withdrawn from the market. Other drugs have been found recently as illegal ingredients in weight loss supplements.

It is illegal, of course, to add prescription drugs to dietary supplements. It is also illegal to market a product without identifying the active ingredients. Such ingredients can cause many problems for users. The most immediate problems include unexpected drug reactions, interactions with other drugs or foods, and allergic reactions. These are big problems for products which have few if any real benefits. Promotional materials that promise dramatic weight loss are unrealistic. "Easy" weight loss, with no dieting or exercise, is impossible for most people. If there were a truly effective easy method, the results would be published in peer-reviewed journals. Media coverage would be guaranteed! Weight loss supplements, along with other types of dietary supplements, are sold online, in stores, and through TV ads. They are often expensive. It can be hard for consumers to get their money back when a product doesn't work. Weight loss fraud is the leading cause of fraud in the U.S. The U.S. Food and Drug Administration (FDA) is not permitted to regulate dietary supplements as it does medicines. It can remove supplements from the market when they are shown to be tainted, contaminated, or improperly labeled. When it finds such products, they are recalled. Companies that market them can be sued. The old saying is true for tainted modern dietary supplements: if something seems too good to be true, it probably is. For anyone who needs to lose weight, the old advice still applies: check with your health care provider.

Learn about nutrition that meets your health needs.

Exercise safely and consistently.

If you think someone is having a reaction to a dietary supplement, don't try to ignore it. If the person is having seizures, not breathing, or has collapsed, call 911. For other symptoms, or if you think you're having a reaction to a hidden ingredient, call 1-800-222-1222. Or use the webPOISONCONTROL® online tool for guidance if too much was swallowed. Whether online or by phone, Poison Control provides expert guidance 24 hours a day.
