As we approach the mid-year mark of 2026, the regulatory landscape for the US supplement industry is undergoing significant transformations. While no single event has caused a seismic shift, the cumulative impact of various initiatives and proposals is prompting a reevaluation of compliance strategies and risk management.
The Human Foods Program (HFP) at the FDA has outlined its priorities for the year, with a focus on food chemical safety, nutrition, and microbiological food safety. Although dietary supplements are not the primary focus, their inclusion within the newly established Office of Food Chemical Safety, Dietary Supplements & Innovation positions them as a key consideration.
Revisiting GRAS Substances
One of the most prominent regulatory priorities is the revisiting of Generally Recognized as Safe (GRAS) substances. The FDA aims to close what it describes as the "GRAS loophole" by requiring mandatory GRAS notices for all new substances claimed to be GRAS. This move is expected to increase FDA scrutiny of novel ingredients, impacting compliance costs and timelines, and potentially influencing innovation strategies.
The proposed rule, scheduled for publication in December 2026, will amend FDA regulations to require mandatory GRAS notices for certain human and animal food substances, establish a comprehensive GRAS notice inventory, and clarify the determination process for GRAS substances.
Exploring Dietary Ingredient Scope
The FDA's public meeting in March focused on the scope of permissible dietary ingredients, particularly in light of scientific and technological advancements. The discussion centered on whether the FDA should modernize its interpretation to accommodate novel ingredients developed through precision fermentation, cell culture technology, and recombinant production.
Additionally, the identity of notable supplement ingredients, such as proteins, enzymes, and microorganisms, which are not specifically listed in the Food Drug and Cosmetic Act, was under consideration. This exploration aims to ensure that the regulatory framework keeps pace with the evolving nature of dietary supplements.
Expanding State Regulation
State policymakers are increasingly shaping the regulatory landscape for dietary supplements through legislation, enforcement actions, and environmental initiatives. This has resulted in a fragmented compliance environment, posing a greater day-to-day compliance burden for companies navigating a patchwork of state regulations.
States are taking the lead in addressing the federal "GRAS loophole" by implementing strict disclosure databases and ingredient bans, promoting greater transparency and strengthening safety oversight. While these initiatives primarily focus on conventional food additives, they reflect a broader trend of states filling regulatory gaps where federal oversight is perceived as inadequate.
Congressional Proposals and FTC Enforcement
Congressional action has centered on three main pieces of legislation, primarily debating the balance between increased federal oversight, state regulation, and consumer access. Notably, Senator Dick Durbin's reintroduction of the Dietary Supplement Listing Act of 2026 is a significant development, marking his final push before retirement.
Durbin argues that the absence of a provision requiring companies to register their products with the FDA in the Dietary Supplement Health and Education Act (DSHEA) of 1994 has left the agency ill-equipped to oversee a market that has grown exponentially.
The Federal Trade Commission (FTC) has also reaffirmed its focus on substantiating consumer-facing claims with competent and reliable evidence. Areas of scrutiny include weight loss and body composition claims, performance and cognitive benefit claims, influencer marketing, and broad "natural," purity, and sustainability positioning.
One notable enforcement action saw the FTC sue multilevel marketer Amare Global for allegedly misrepresenting the health benefits of its supplements and misleading seller recruits about potential earnings.
Conclusion
The regulatory environment for the US supplement industry is in a state of flux, with various initiatives and proposals shaping compliance strategies and risk management. The cumulative effect of these changes is prompting a reevaluation of how companies approach regulatory compliance, especially as the industry continues to evolve and expand.
From my perspective, the industry's ability to adapt to these regulatory changes will be crucial in ensuring consumer safety and maintaining trust in the market. It's an exciting time for the industry, and I look forward to seeing how these developments unfold and shape the future of dietary supplements.
