Washington, D.C. — The Council for Responsible Nutrition (CRN), the leading trade association representing dietary supplement manufacturers and ingredient suppliers, today expressed strong support for the introduction of the Dietary Supplement Regulatory Uniformity Act by Congressman Nick Langworthy (R-NY-23), legislation that reaffirms the U.S. Food and Drug Administration’s (FDA) authority as the national regulator of dietary supplements.
For over 30 years, dietary supplements have been regulated under a consistent, science-based federal framework that ensures products are safe, properly labeled, and marketed responsibly. The new legislation reinforces that system by preventing individual states from creating conflicting or duplicative supplement regulations that undermine federal oversight and create confusion for consumers and businesses alike.
“Americans benefit when dietary supplements are regulated under one clear, national standard grounded in science,” said Steve Mister, President and CEO of CRN. “This legislation protects consumers from confusing and alarmist state-level restrictions and requirements while ensuring responsible companies can continue to innovate and provide safe, high-quality products nationwide.”
In recent years, some states have begun advancing supplement laws that are inconsistent with FDA requirements, creating a patchwork of rules that increase compliance costs, strain retailers, disrupt national supply chains, and threaten consumer access to lawful products. Recent legislation in Texas that would have imposed additional labeling for melatonin, in California that would disrupt federal expiration dating standards, and in Massachusetts that would restrict safe products such as protein, creatine, and amino acids all highlight the risks of permitting states to impose restrictions and warnings that are not supported by FDA safety determinations.
The Dietary Supplement Regulatory Uniformity Act restores clarity by affirming that only FDA can establish regulatory requirements for dietary supplements, while still allowing states to petition the agency if they can demonstrate a legitimate local concern. This balanced approach preserves flexibility without sacrificing consistency or scientific rigor. Importantly, the legislation does not prevent states from enforcing identical state versions of federal requirements to supplement federal oversight with their own enforcement resources.
“Strong federal oversight and uniform enforcement are essential to maintaining consumer confidence and ensuring a level playing field for responsible businesses,” Mister added. “CRN commends lawmakers for taking action to keep dietary supplement policy grounded in science—not sensationalism.”
CRN appreciates Congressman Langworthy’s leadership and urges Congress to advance the Dietary Supplement Regulatory Uniformity Act and looks forward to working with policymakers, FDA, and other stakeholders to strengthen consumer protections while preserving access to safe and beneficial dietary supplements.
