Speaking before the American Society for Pharmacology and Experimental Therapeutics (ASPET) and the American Society for Nutritional Sciences, Dr. Lester M. Crawford, Acting Commissioner of the Food and Drug Administration (FDA), today outlined the agency's science-based approach to protecting American consumers from unsafe dietary supplements.
Dr. Crawford said the agency would soon provide further details about its plan to ensure that the consumer protection provisions of the 1994 Dietary Supplement Health and Education Act (DSHEA) are used effectively and appropriately. Through DSHEA, which sets up a distinct regulatory framework for dietary supplement products, Congress attempted to strike a balance between providing consumers access to dietary supplements and giving FDA regulatory authority to act against supplements or supplement ingredients that present safety problems, are marketed with false or misleading claims, or are otherwise adulterated or misbranded.
"FDA is absolutely committed to protecting consumers from misleading claims and unsafe products," said Dr. Crawford. "Unlike most foods, some dietary supplements are pharmacologically active. And we have seen over the last 10 years a huge growth in the dietary supplements industry, including the introduction of products that seem far removed from the vitamins and minerals of the pre-DSHEA days. We have become increasingly aware of the potential health problems some of these products pose."
In the last 6 months, FDA has inspected 180 domestic dietary supplement manufacturers; sent 119 warning letters to dietary supplement distributors; refused entry to 1,171 foreign shipments of dietary supplements; and seized or supervised voluntary destruction of almost $18 million worth of mislabeled or adulterated products. "We will continue to aggressively enforce DSHEA against unsafe or mislabeled products," Crawford said.
In March FDA requested that 23 companies cease distributing dietary supplements containing androstenedione, which are marketed to stimulate testosterone and muscle growth but have anabolic steroid effects in the body.
Over the next several months FDA will provide additional information to explain and implement the tools available to the agency under DSHEA to act against unsafe supplements and false or misleading supplement labeling claims.
FDA is also developing regulations for industry on good manufacturing practices (GMPs). When finalized, this rule, proposed last spring, will help protect consumers from dietary supplements that contain impurities or contaminants as a result of how they are manufactured or handled.
FDA is, in addition, putting dietary supplement labeling under closer scrutiny. Dietary supplement labels cannot claim the supplement will treat or cure a disease, and since December 2002 FDA has worked with the Federal Trade Commission to challenge false claims of supplement effectiveness for treating a range of diseases.
