Current Good Manufacturing Practice for Dietary Supplements
The cGMP regulation for manufacturing, packaging, labeling, and holding dietary supplements. It requires identity testing of incoming dietary ingredients, established specifications, quality-control oversight, and full batch documentation — bringing pharmaceutical-style controls to the supplement industry.
What this does not cover
stated in the document's own scope- Covers dietary supplements as defined by DSHEA, not conventional foods (21 CFR Part 117) or drugs (21 CFR Parts 210–211).
- Governs manufacturing quality, not label content and structure/function claims, which are addressed by separate FD&C Act labelling provisions and regulations.
- Sets GMP for the finished supplement and its dietary ingredients, not the safety substantiation of a new dietary ingredient, which follows a distinct notification requirement.
Always verify against the current published text before relying on it for a submission or inspection.
Overview
21 CFR Part 111 is the current Good Manufacturing Practice regulation for dietary supplements — covering their manufacturing, packaging, labelling, and holding. It requires a manufacturer to establish specifications for identity, purity, strength, and composition, and for limits on contamination; to test or examine incoming dietary ingredients to confirm identity; to operate under a quality-control function that reviews and approves records and material dispositions; and to keep complete batch production records. It brought supplement manufacturing under a defined, verifiable set of quality controls comparable in structure to pharmaceutical GMP, scaled to the sector.
Scope & applicability
Manufacturers, packagers, labelers, and holders of dietary supplements distributed in the United States.
Legal basis & how it acquires force
Part 111 is a binding regulation in Title 21 CFR, issued under the Federal Food, Drug, and Cosmetic Act, which was amended by the Dietary Supplement Health and Education Act of 1994 (DSHEA) to create the dietary-supplement category and authorise GMP requirements for it. The final rule published in 2007, with compliance phased in by company size through 2010. It treats a dietary supplement made outside these practices as adulterated, tying compliance directly to the product’s legal marketability.
Document structure
| Part | Covers |
|---|---|
| Subparts A–B | General provisions and definitions; personnel requirements including qualification and hygiene |
| Subparts C–D | Physical plant and grounds; equipment and utensils, their design, cleaning, and maintenance |
| Subpart E | Requirement to establish a production and process control system, including the quality-control function |
| Subparts F–G | Quality-control operations and duties; components, packaging, labels, and product received for packaging or labelling |
| Subparts H–K | Master manufacturing and batch production records; laboratory operations; manufacturing, packaging, labelling, and holding operations |
| Subparts L–P | Holding and distributing; returned supplements; product complaints; and required records and recordkeeping |
Key requirements
- Establish specifications for identity, purity, strength, and composition
- Conduct identity testing on every incoming dietary ingredient
- Maintain a Master Manufacturing Record and a complete Batch Production Record per batch
- Operate an independent quality-control function that approves and rejects
- Investigate and document any specification failure
Implementation tips
- Identity-test every incoming dietary ingredient — a supplier CoA alone is not sufficient
- Keep the Master Manufacturing Record and Batch Production Record reconcilable batch to batch
- Give QC genuine authority to reject — inspectors probe its independence
Revision notes
Issued in 2007 with a phased compliance schedule; remains the governing US cGMP for dietary supplements.

International alignment
Part 111 is a US-specific regulation created by DSHEA and has no single international equivalent, though its structure parallels the pharmaceutical cGMP of Part 211 and shares GMP concepts with the food rules of Part 117; some supplement makers also certify to voluntary schemes and to Codex or ISO food-safety references. Because it is built on the DSHEA definition of a dietary supplement, its scope is set by that US statutory category rather than by an ICH-style harmonised guideline.
21 CFR Part 111: frequently asked questions
Quick answers to common questions about 21 CFR Part 111.
What statute created the need for 21 CFR Part 111?
The Dietary Supplement Health and Education Act of 1994 (DSHEA), which amended the Federal Food, Drug, and Cosmetic Act to define dietary supplements and authorise GMP requirements for them. Part 111 is FDA’s implementing regulation, finalised in 2007.
Does Part 111 require identity testing of ingredients?
Yes. Part 111 requires a manufacturer to establish specifications and to confirm the identity of incoming dietary ingredients, among other quality controls, before they are used.
Is Part 111 the same as food GMP?
No. Part 111 is specific to dietary supplements under the DSHEA category. Conventional human food is covered by 21 CFR Part 117, which shares GMP concepts but is a separate rule.
