The U.S. Food and Drug Administration (FDA) has issued a warning to consumers regarding 46 specific weight loss and male enhancement products. Laboratory analysis of these products found active pharmaceutical ingredients not listed on the labels. Many of these hidden ingredients are approved for use by prescription only and could cause potentially serious side effects or interfere with other medications or dietary supplements. See the FDA’s Tainted Products Marketed as Dietary Supplements database (https://www.accessdata.fda.gov/scripts/sda/sdnavigation.cfm?sd=tainted_supplements_cder) for more information.
The products tested were purchased by the FDA online from Amazon and eBay. Twenty of the 25 weight loss and male enhancement products purchased on eBay and all 26 of the products purchased from Amazon—some of which were designated as an “Amazon Choice” or “#1 Best Seller”—contained potentially hazardous ingredients. This does not mean all products purchased at these sites are dangerous: the FDA buyers chose products that had names similar to tainted products that had been the subject of previous consumer warnings.
Dietary supplements are not subject to testing and approval before going to market. The FDA is unable to test every product for sale. Be on alert for products that offer quick results which sound too good to be true, especially those promoted for sexual enhancement, weight loss, bodybuilding, sleep aid, or pain relief.
