Who Regulates Dietary Supplements?
Contrary to a common misconception, the USDA is not responsible for the oversight of dietary supplements. The regulatory landscape for these products is complex and primarily involves two other federal agencies: the Food and Drug Administration (FDA) and the Federal Trade Commission (FTC). The FDA's authority is defined by a specific law, the Dietary Supplement Health and Education Act (DSHEA) of 1994, which treats supplements differently than conventional foods and drugs.
The FDA and the DSHEA
Under the DSHEA, the FDA’s role is primarily reactive rather than proactive. This means that unlike with new drugs, the FDA does not pre-approve dietary supplements for safety or effectiveness before they are marketed. Instead, manufacturers and distributors are responsible for ensuring their products are safe and that any claims made about them are truthful and not misleading. The FDA only steps in to take action against a product that is already on the market if it is proven to be unsafe, adulterated, or misbranded. This could involve issuing warnings or forcing a recall. The FDA also has the authority to inspect manufacturing facilities to ensure compliance with good manufacturing practices (GMPs).
The FTC and Advertising Claims
While the FDA regulates the claims made on a supplement's label and packaging, the FTC oversees the claims made in all other forms of advertising, such as on websites, in commercials, or in print ads. The FTC requires that all health-related claims be truthful, substantiated by competent and reliable scientific evidence, and not deceptive. This creates a system where the FDA handles the product itself and the FTC manages the marketing messages that reach consumers. The two agencies work together, though they operate under different legal frameworks.
A Closer Look at the Regulatory Landscape
To better understand the distinct roles, consider these specific responsibilities:
- FDA Responsibilities:
- Monitoring product safety after it reaches the market.
- Investigating reports of adverse events and taking action against unsafe products.
- Establishing and enforcing GMPs for manufacturing facilities.
- Regulating the claims made on product labels.
- Taking action against products that are adulterated or misbranded.
- FTC Responsibilities:
- Ensuring marketing and advertising claims are truthful and not misleading.
- Requiring that advertising claims are backed by scientific evidence.
- Taking action against deceptive marketing practices.
Comparison of Regulatory Agencies for Supplements
| Agency | Regulatory Focus | Scope for Supplements |
|---|---|---|
| USDA | Meat, poultry, egg products, agricultural goods, and specific origin claims. | None. The USDA plays no role in the regulation of dietary supplements. |
| FDA | Safety, labeling, and manufacturing practices. | Post-market surveillance. Can take action against unsafe or mislabeled products. |
| FTC | Advertising and marketing claims. | Ensures advertising is truthful and not deceptive, substantiated by evidence. |
How Consumers Can Vet Supplements
Given the less strict pre-market oversight, consumers must be vigilant. Here are some steps to take:
- Look for Third-Party Certification: Some organizations, like the U.S. Pharmacopeia (USP), NSF International, and ConsumerLab.com, offer voluntary third-party testing to verify ingredients and quality. Look for their seals on the product label. A list of USP-verified products is available on the Quality Supplements website.
- Research the Manufacturer: A reputable manufacturer will have a transparent website and provide contact information. Investigate their history and any past FDA warnings.
- Consult a Healthcare Professional: Before taking any new supplement, especially if you have a health condition or are taking medication, discuss it with a doctor or registered dietitian.
- Be Skeptical of Exaggerated Claims: If a product promises a miracle cure or sounds too good to be true, it likely is. These claims often violate FTC regulations.
Conclusion
To be clear, the USDA does not regulate dietary supplements. The regulatory authority falls under the purview of the FDA and the FTC, operating within a framework established by the DSHEA. While the FDA monitors products once they are on the market, the ultimate responsibility for ensuring a supplement's safety and efficacy falls on the manufacturer. For consumers, this highlights the importance of thorough research and critical evaluation of products and their claims before making a purchase. Understanding the roles of the FDA and FTC is crucial for navigating the supplement market responsibly.

Summary of Key Regulatory Points
- No USDA Regulation: The USDA does not oversee dietary supplements, focusing instead on meat, poultry, and certain other food products.
- FDA is the Primary Regulator: The Food and Drug Administration (FDA) is the key federal agency responsible for supplement regulation, operating under the DSHEA.
- Post-Market Surveillance: The FDA does not approve supplements before they are sold; it instead monitors the market for safety, taking action against products found to be unsafe or misbranded.
- FTC Handles Advertising: The Federal Trade Commission (FTC) is responsible for ensuring that all health-related advertising claims made about supplements are truthful and scientifically substantiated.
- Manufacturer's Responsibility: Under the DSHEA, supplement manufacturers and distributors bear the primary legal responsibility for the safety of their products.
