Revise Dietary Supplement Listing Bill: Researchers

Share

Harvard Medical School researchers say proposed legislation to require dietary supplement manufacturers to provide FDA with some basic information should be revised significantly to make it a true reform and oversight bill. Writing in a New England Journal of Medicine opinion piece, the researchers say the Dietary Supplement Listing Act of 2022 as introduced by Sens. Dick Durbin (D-IL) and Mike Braun (R-IN) would end up institutionalizing misinformation through the FDA Web site.

The bill would require supplement manufacturers to provide FDA with a product’s name, ingredients, and health claims. It also would require FDA to create and maintain a publicly searchable database of the estimated 80,000 supplement products available for sale in the U.S.

“FDA has sought enhanced capabilities for promoting supplement safety, suggesting that certain steps, including the establishment of a registry, would permit the agency to ‘take appropriate action to protect consumers’ from dangerous supplements,” the article says. “There is little chance, however, that the proposed law would meet these important clinical and public health goals; rather, it would create the impression of reform while leaving the current lax regulatory framework largely untouched.”

The researchers say the bill should be extensively revised to introduce basic safeguards. “Congress could give FDA the authority to read a supplement’s label before registering the product and not register the product if the label lists unlawful ingredients or claims,” they write. “The bill could also be revised to permit FDA to swiftly remove products from the registry if the agency determines that they are hazardous…. The legislation could require manufacturers to submit a certificate of analysis to ensure that labels are adequate representations of products’ ingredients. In addition, to avoid misleading consumers, health claims submitted to FDA shouldn’t be posted publicly on its Web site unless the agency confirms that they are supported by high-quality clinical trials.”
