To help consumers make wise choices and avoid falling prey to dietary supplement fraud, the U.S. Food and Drug Administration (FDA) recently released a Consumer Update to address the topic. Unlike some previous education efforts warning consumers away from all weight-loss supplements, the FDA is focused on practical measures for separating fact from fiction.
In recent years, supplements sold by unscrupulous retailers containing numerous powerful drugs have found their way into consumers’ hands through Internet and in-store sales. Some “natural” diet products have been found to contain sibutramine (Meridia), a weight-loss medication removed from the market in 2010 because it increases risk of heart problems and strokes. Other FDA research has uncovered weight-loss supplements contaminated with seizure and blood pressure medications, and even prescription drugs that were never approved at all.
The most important tip-off that a supplement may not be legitimate or pure are claims that are too good to be true. Products that promise quick action (“Lose 20 pounds in 10 days!”), that tout a revolutionary new scientific breakthrough, or that are marketed as having actions similar to FDA-approved weight-loss medications should raise a red flag. These products may contain unapproved or potentially harmful ingredients, including prescription medications.
In addition to paying attention to aggressive product claims, a few tips will help you make the most of any dietary supplement you decide to try.
