The FDA requires all dietary supplement manufacturers, packagers, labelers, and holders to comply with 21 CFR Part 111 — Current Good Manufacturing Practice in Manufacturing, Packaging, Labeling, or Holding Operations for Dietary Supplements.
These regulations cover every aspect of your supplement operation: production and process controls, quality control procedures, packaging and labeling operations, and holding and distribution. The goal is to ensure that dietary supplements are manufactured consistently and meet established quality standards.
Non-compliance with 21 CFR Part 111 can result in serious consequences, including FDA warning letters, import alerts, product seizures, injunctions, and even criminal prosecution. The FDA has significantly increased enforcement actions against supplement companies in recent years.
Working with an experienced dietary supplement GMP consultant ensures your facility, processes, and documentation meet every FDA requirement — before an inspector arrives at your door.
21 CFR Part 111 Covers:
Personnel & employee qualifications
Physical plant & facility requirements
Equipment & utensil controls
Production & process controls
Quality control operations
Packaging & labeling operations
Holding & distribution requirements
Returned products & product complaints

Common Questions
Frequently Asked Questions
What is 21 CFR Part 111?
21 CFR Part 111 is the FDA regulation that establishes Current Good Manufacturing Practice (cGMP) requirements for the manufacturing, packaging, labeling, and holding of dietary supplements. It requires manufacturers to ensure product identity, purity, strength, and composition. Compliance is mandatory for all companies that manufacture, package, label, or hold dietary supplements sold in the United States.
How often does the FDA inspect supplement facilities?
The FDA inspects domestic dietary supplement facilities on a risk-based schedule. High-risk facilities may be inspected every 1-2 years, while lower-risk facilities may go 3-5 years between inspections. However, the FDA can inspect at any time, especially in response to consumer complaints, adverse event reports, or product recalls. Being inspection-ready at all times is essential.
What is the difference between GMP and NSF certification?
FDA GMP compliance under 21 CFR Part 111 is a legal requirement for all dietary supplement manufacturers. NSF certification is a voluntary, third-party certification that goes beyond FDA requirements. NSF certification (such as NSF/ANSI 173 or NSF Certified for Sport) demonstrates additional commitment to quality and can open doors to major retailers and the sports nutrition market. GMP is the baseline; NSF certification is a competitive differentiator.
How long does GMP implementation take for a supplement company?
GMP implementation for dietary supplement companies typically takes 3 to 6 months, depending on the size of the operation, the current state of your quality systems, and the complexity of your product line. Companies with existing quality systems in place can often achieve compliance faster. Our expert consultants use a proven 8-step process designed to minimize disruption while ensuring thorough, audit-ready implementation.
