Makers of dietary supplements push the FDA to allow peptides and other new ingredients

The dietary supplement industry is lobbying the FDA to broaden its rules on what ingredients manufacturers can use in their products, specifically seeking approval for peptides and other novel compounds currently restricted or undefined under federal law. The FDA has long regulated dietary supplements under a framework that limits them to vitamins, minerals, amino acids, and other traditional ingredients, while peptides—short chains of amino acids—exist in a regulatory gray area. If the agency expands what's permissible, manufacturers could market a wider range of anti-aging, muscle-building, and performance-enhancing products without the stringent approval process required for pharmaceutical drugs. The petition highlights a broader tension between an industry seeking innovation and regulators concerned about consumer safety and efficacy standards. The FDA has not yet signaled whether it will grant the request.
