Whether you’re looking to buy weight loss, male enhancement, or certain other products, these days you’re apt to look for them online, rather than at a physical store. But buyer, beware. When you buy such products, you may actually be getting an illegal product; and that product may contain potentially dangerous ingredients that are not on the label. This is not a new development. Over the past decade, the U.S. Food and Drug Administration has frequently warned consumers that certain products sold over-the-counter - including those sold over the "virtual" counter - contain hidden active ingredients that could be harmful. Hidden ingredients are a problem in products promoted for weight loss, body building, pain relief, sleep aids, and sexual enhancement. Often, products containing active ingredients in FDA-approved drugs are falsely represented as dietary supplements. It is clear from the results of our decade of testing that retailers and distributors, including online marketplaces, do not effectively prevent these types of potentially harmful products from being sold to consumers.
