US Regulators Propose Tighter Dietary Supplement Rules

Live Poll

Should the federal government implement stricter regulations on the dietary supplement industry?

US regulators are moving toward stricter oversight of dietary supplement ingredients to improve product safety. This shift comes as a growing number of the 10 million Americans using GLP-1 drugs turn to supplements to help manage side effects.

Why it matters

Health officials aim to strengthen ingredient oversight as the market expands rapidly, with many supplement makers currently bypassing the full FDA review process by declaring new ingredients as generally recognized as safe.

US vitamin and supplement sales reached US$74 billion in 2025, with TikTok Shop accounting for over US$1 billion in sales. GLP-1 users have reported a 20% increase in supplement spending to address symptoms like gastrointestinal distress.

The players

Robert F. Kennedy Jr.

He is the United States Secretary of Health and Human Services and has proposed stricter regulations on supplement ingredients.

Procter & Gamble

This multinational consumer goods corporation is moving to expand its portfolio by acquiring the supplement maker Thorne.

Kirin Holdings

This Japanese food and beverage company has announced plans to purchase Jamieson Wellness.

FDA

The Food and Drug Administration is the federal agency responsible for regulating dietary supplements and safety standards.

The details

Supplement manufacturers frequently utilize social media influencers to promote products while using a safety declaration pathway to avoid formal FDA review. Health and Human Services Secretary Robert F. Kennedy Jr. has proposed these tighter regulations to ensure that new dietary ingredients meet strict safety standards.

2023 marked the beginning of widespread GLP-1 drug usage.
Supplement sales growth reached 5% in 2024.
Approximately 10 million Americans used GLP-1 drugs in 2025.
The FDA issued new guidance for ingredient submissions in 2026.
The number of Americans using GLP-1 drugs could reach 25 million by 2030.

The Big Picture

The proposed regulations mark a significant tightening of the FDA's Generally Recognized as Safe (GRAS) notification process, which currently allows companies to bypass mandatory safety reviews. This shift moves the industry away from self-policing toward a more rigorous federal oversight model.

Patients managing GLP-1 side effects may see changes in the availability or variety of supplements currently marketed for gastrointestinal health and fatigue. These regulatory changes could also lead to higher transparency regarding the scientific backing of over-the-counter ingredients.

The takeaway

Consumers should remain cautious of social media claims regarding supplements, as many products currently reach the market without formal FDA oversight. Checking for third-party certifications can help verify product quality while new federal safety guidelines remain in development.
