Understanding Dietary Supplement Regulations
The dietary supplement industry in the United States is primarily governed by the Dietary Supplement Health and Education Act of 1994 (DSHEA), which amended the Federal Food, Drug, and Cosmetic Act. Under this framework, dietary supplements are regulated as a category of food, not as drugs, which means they do not require FDA pre-market approval before entering the marketplace.
However, this does not mean the industry is unregulated. Dietary supplement manufacturers bear significant responsibility for ensuring their products are safe, properly manufactured, and accurately labeled. FDA has established comprehensive current Good Manufacturing Practice (cGMP) regulations specifically for dietary supplements under 21 CFR Part 111, and enforces strict requirements regarding labeling claims, new dietary ingredients, and adverse event reporting.
The regulatory landscape for dietary supplements continues to evolve. Recent years have seen increased FDA enforcement actions, heightened scrutiny of New Dietary Ingredients (NDIs), and growing attention to issues such as undeclared drug ingredients and contamination. Companies operating in this space must stay informed of regulatory developments and maintain robust compliance programs.
Key Regulatory Framework
The foundation of dietary supplement regulation rests on several key statutes and regulations:
What is a Dietary Supplement?
Under DSHEA, a dietary supplement is a product taken by mouth that contains a "dietary ingredient" intended to supplement the diet. Dietary ingredients include:
The product must be intended for ingestion and be labeled as a dietary supplement. Products that make drug claims (claims to diagnose, treat, cure, or prevent disease) may be regulated as drugs regardless of their composition.

Key Compliance Requirements
Dietary supplement companies must meet these fundamental regulatory requirements to legally market products in the United States.
FDA Facility Registration
All dietary supplement facilities must register with FDA and renew biennially
cGMP Compliance
21 CFR Part 111 requires comprehensive manufacturing controls
Product Labeling
Supplement Facts panel, ingredient list, and required statements
New Dietary Ingredient (NDI)
75-day premarket notification required for new ingredients
cGMP Compliance (21 CFR Part 111)
The dietary supplement cGMP rule establishes comprehensive requirements for manufacturing, packaging, labeling, and holding operations. Compliance is mandatory for all manufacturers regardless of company size.
These regulations ensure that dietary supplements are produced in a quality manner, do not contain contaminants or impurities, and are accurately labeled. FDA conducts regular inspections to verify compliance.
Key cGMP Elements
Labeling Requirements
Dietary supplement labels must include specific information in the format and location required by FDA regulations.
Label Requirements
Required Disclaimer
If making structure/function claims, you must include:
Prohibited Claims
Dietary supplements cannot make disease claims such as "treats diabetes" or "cures cancer." Such claims render the product an unapproved drug subject to FDA enforcement action.
Common Violations to Avoid
Learn from others' mistakes. These are the most frequently cited violations in FDA warning letters to dietary supplement companies.
Failure to verify identity of dietary ingredients
Warning letter, product seizure, import refusal
Implement 100% identity testing of incoming materials
Inadequate master manufacturing records
Warning letter, potential recall
Maintain complete written procedures for each product
Unapproved disease claims on labels
Products deemed unapproved drugs, seizure
Review all claims with regulatory expert before use
No NDI notification for new ingredients
Products deemed adulterated, FDA action
Evaluate all ingredients for NDI status before marketing
Frequently Asked Questions
Get answers to the most common questions about dietary supplement FDA compliance.
What is DSHEA and how does it affect my supplements?
The Dietary Supplement Health and Education Act of 1994 (DSHEA) defines dietary supplements and establishes their regulatory framework. Under DSHEA, supplements are regulated as a category of food, not drugs. This means manufacturers are responsible for ensuring their products are safe before marketing, and FDA does not approve dietary supplements before they enter the market. However, manufacturers must still comply with cGMP requirements, proper labeling, and cannot make drug claims.
Do I need FDA approval to sell dietary supplements?
No, dietary supplements do not require FDA pre-market approval. However, you must: (1) Register your facility with FDA, (2) Ensure your products are safe and properly labeled, (3) Comply with cGMP regulations (21 CFR Part 111), (4) Submit NDI notifications for any new dietary ingredients, and (5) Not make drug claims. FDA can take action against products that are unsafe, mislabeled, or make illegal claims.
What qualifies as a New Dietary Ingredient (NDI)?
A New Dietary Ingredient (NDI) is a dietary ingredient that was not marketed in the United States before October 15, 1994. If your product contains an NDI, you must submit a notification to FDA at least 75 days before marketing, providing evidence of reasonable expectation of safety. Ingredients with a history of use in food (not supplements) before 1994 may also require NDI notification.
What are the cGMP requirements for dietary supplements?
The dietary supplement cGMP rule (21 CFR Part 111) requires manufacturers to establish and follow written procedures for manufacturing, packaging, labeling, and holding operations. Key requirements include: identity testing of 100% of incoming dietary ingredients, establishing product specifications, maintaining batch records, written CAPA procedures, personnel training, and equipment maintenance. All manufacturers, regardless of size, must comply.
Can I make health claims on my supplement labels?
There are three types of claims allowed on dietary supplements: (1) Health claims - must be authorized by FDA or based on authoritative statements, (2) Qualified health claims - supported by some evidence but not enough for an authorized claim, (3) Structure/function claims - describe how a nutrient affects body structure or function. Structure/function claims require a disclaimer and 30-day notification to FDA. Disease claims ("treats diabetes") are never allowed without drug approval.
What is the required disclaimer for dietary supplements?
If you make structure/function claims, your label must include the following disclaimer: "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." This disclaimer must appear in boldface type, enclosed by a box, and placed adjacent to the claim.
How often must I renew my FDA facility registration?
FDA food facility registration, which includes dietary supplement facilities, must be renewed every two years (biennially) during the renewal period of October 1 through December 31 of even-numbered years. Failure to renew results in cancellation of your registration, and you cannot legally manufacture, process, pack, or hold dietary supplements without a valid registration.
Do foreign supplement manufacturers need a US Agent?
Yes, all foreign facilities that manufacture, process, pack, or hold dietary supplements for US export must designate a US Agent. The US Agent must reside in the US or maintain a place of business in the US, and acts as a communication liaison between FDA and the foreign facility. The US Agent receives FDA communications and must be available 24/7 for emergencies.
What testing is required for dietary supplements?
cGMP requires: (1) Identity testing of 100% of incoming dietary ingredients, (2) Testing to ensure product meets specifications, (3) Testing for contaminants if warranted by the manufacturing process. You can use certificates of analysis from suppliers but must verify supplier reliability. Many companies also test finished products for potency, purity, and contaminants like heavy metals, pesticides, and microorganisms.
What happens if FDA finds violations at my facility?
If FDA inspectors find violations, you may receive a Form FDA 483 listing observations. You must respond within 15 business days addressing each observation. If violations are serious, FDA may issue a Warning Letter requiring corrective action. Continued non-compliance can result in import alerts, seizure of products, injunctions, or criminal prosecution. Prompt corrective action and documented CAPA is essential.
