21 CFR Part 111 establishes the FDA's cGMP requirements for dietary supplement manufacturers. Affinity QMS maps every Part 111 subpart to purpose-built modules so your facility stays inspection-ready without the overhead of enterprise QMS software.
21 CFR Part 111 establishes Current Good Manufacturing Practice (cGMP) requirements for all companies that manufacture, package, label, or hold dietary supplements. The regulation covers facilities, equipment, production and process controls, quality control operations, and record-keeping. The FDA enforces Part 111 through routine facility inspections and can take action for violations including warning letters, injunctions, and product seizures.

Expandable Certifications
Affinity QMS supports Part 111 compliance as a foundation for expanding into voluntary certifications that supplement brands and retailers increasingly require from their manufacturing partners.
Each Part 111 subpart maps to an Affinity QMS module. No duplicate tools. No manual workarounds. One platform from batch record to audit report.

| 111.70–111.77 | Component & Supplier Qualification | Supplier Management | Approved vendor list, supplier qualification questionnaires, certificate of analysis management, incoming inspection records |
| 111.90–111.95 | Corrective & Preventive Action | CAPA Management | CAPA initiation from deviations or complaints, root cause analysis, corrective action implementation, effectiveness checks |
| 111.75(a) | Written Procedures | Document Control | Controlled SOPs, work instructions, master manufacturing records; version control; approval workflows |

| 111.315 | Record Retention | QMS Core | Configured retention schedules per record type; secure storage; audit trail for all records |
Dietary supplement manufacturers at every stage face Part 111 compliance pressure. Affinity QMS serves all three buyer profiles.
Supplement Brand Founder / Operations Lead
Launching or scaling a supplement brand and need to establish cGMP-compliant documentation before the first FDA inspection or retail buyer audit. Wants supplier qualification and batch records done right without hiring a consultant.
QA Manager at a Contract Manufacturer
Running quality for a contract supplement manufacturer servicing multiple brands. Needs one system that manages batch records, supplier qualification, and complaints across multiple product lines. NSF or Informed Sport certification is on the roadmap.
Private Label Operation Scaling to 503B or OTC
Supplement company expanding into OTC drug products or co-packing arrangements that require Part 211 in addition to Part 111. Needs a platform that can grow with them into pharmaceutical-grade cGMP without a system migration.
Dietary supplement cGMP compliance often overlaps with food safety (Part 117), pharmaceutical standards (Part 211), and voluntary certification programs.
Part 111 requires a comprehensive set of records including: Master Manufacturing Records (MMR) for each unique formulation, Batch Production Records (BPR) for each batch produced, laboratory records for all testing performed, complaint records for each consumer complaint received, supplier qualification records (certificates of analysis, qualification documentation), training records for all qualified personnel, and equipment cleaning and maintenance records. Most records must be retained for one year past the shelf life of the product, or two years from the date of distribution, whichever is longer. Affinity QMS manages all of these record categories in a single audit-ready system.
The FDA uses a risk-based inspection schedule for dietary supplement facilities. High-risk facilities — those with prior violations, complaint history, or high-volume production of high-risk products — may be inspected annually. Most facilities can expect an inspection every two to five years. However, the FDA can conduct an unannounced for-cause inspection at any time following consumer complaints, adverse event reports, or media incidents. The only reliable strategy is to maintain continuous inspection readiness, not to prepare reactively.
Based on FDA warning letters and Form 483 observations, the most frequently cited Part 111 violations include: (1) Failure to establish specifications for components and dietary supplements, (2) Inadequate supplier qualification — accepting ingredients without adequate testing or CoA verification, (3) Missing or incomplete batch production records, (4) Failure to document corrective actions when specifications are not met, (5) Inadequate written procedures for production and process controls, (6) Failure to qualify personnel and maintain training records. Affinity QMS directly addresses each of these with built-in workflows, not just document templates.
Yes. NSF/ANSI 173 (dietary supplement certification) and Informed Sport both build on Part 111 cGMP as a baseline and add additional testing, labeling, and documentation requirements. Affinity QMS provides the Part 111 QMS infrastructure (supplier qualification, batch records, CAPA, document control) that forms the foundation for both certifications. Certification-specific add-on modules for NSF/ANSI 173 and Informed Sport are available to extend the base platform with the additional requirements each program imposes. Your certification auditor reviews your QMS documentation — Affinity QMS makes that documentation instantly available and audit-ready.
21 CFR Part 111 covers dietary supplements specifically — vitamins, minerals, herbs, and other products marketed as dietary supplements under DSHEA. 21 CFR Part 117 covers conventional food products under FSMA's Preventive Controls rule (HARPC). The key distinction: Part 117 requires a written Food Safety Plan including hazard analysis and preventive controls, while Part 111 focuses on cGMP for supplement manufacturing. If your facility manufactures both food products and dietary supplements, you may need to comply with both regulations. Affinity QMS supports both in a single platform, allowing shared infrastructure for document control, supplier management, and CAPA.
Yes — and the cost of not having one is far higher than the cost of Affinity QMS. A single FDA warning letter can cost hundreds of thousands of dollars in remediation, legal fees, and lost revenue. An import alert or consent decree can end a company. Affinity QMS starts at $499 per month for the QMS Core package, which includes document control, training records, and supplier register — everything a small supplement manufacturer needs to satisfy the foundational Part 111 requirements. You add modules only as you need them, keeping costs proportional to your operation size.
Yes. Affinity QMS supports electronic batch production records created from master manufacturing record templates. Each batch record links to the relevant MMR, captures in-process data points, flags deviations for investigation, and requires electronic sign-off at each critical process step. The complete batch record — including all in-process records, deviation reports, and final disposition — is stored in a tamper-evident, date-stamped audit trail. This satisfies Part 111 batch record requirements and makes batch release review dramatically faster than paper-based systems.
From first FDA inspection to NSF certification, Affinity QMS gives dietary supplement manufacturers the cGMP infrastructure they need without the enterprise overhead they don't.
