Overview
What this covers
Dietary supplement manufacturers, packagers, labelers and holders operate under 21 CFR Part 111, a cGMP rule with a structure that differs from the food preventive controls world. It centres on written specifications at every stage, on identity testing of incoming dietary ingredients, and on a quality control unit with genuine authority to reject.
We build and repair those systems: master manufacturing records and batch production records that actually control the process, component and finished-batch specifications with defined test methods, supplier qualification files, and the quality unit review discipline that ties them together. Where a certificate of analysis is being relied on, we make sure the reliance is documented and justified rather than assumed.
Who this is for
- Dietary supplement manufacturers, packagers and labelers subject to 21 CFR Part 111
- Brand owners whose products are made by a contract manufacturer and who hold responsibility for their own labels and claims
- Companies preparing for a first FDA cGMP inspection or a customer or third-party audit
- Operations that need an independent review of master manufacturing records and batch records before scale-up
- Contract manufacturers being qualified by a new brand customer

Engagements are scoped to what applies to your operation. Where a listed service is not relevant to your products, processes or jurisdiction, we will say so.
How an engagement runs
Sequenced so each step earns the next.
Nothing gets written before the operation is verified, and nothing is declared complete before it has been tested against the standard it will be judged by.
Specification architecture
Component, in-process, packaging, label and finished-batch specifications, each with an identified test or examination method and an acceptance criterion. Part 111 findings are frequently specification findings first and testing findings second.
Identity and supplier qualification
Identity verification for incoming dietary ingredients, documented qualification of suppliers, and — where you exempt yourself from a component test by relying on a certificate of analysis — the written justification and periodic confirmation that reliance requires.
Master and batch record build
Master manufacturing records that fix the process, and batch production records that capture what actually happened, including deviations, reconciliation and quality unit review with the supporting data attached.
Quality unit and audit readiness
Defining quality control responsibilities and authority, reviewing a sample of executed batch records the way an investigator would, and dry-running the document requests an inspection or customer audit typically opens with.
Regulatory basis
The requirements behind the work.
Applicability depends on your products, processes, size and jurisdiction. Exemptions and modified requirements exist throughout these rules, and part of the engagement is establishing which apply to you.
Summaries below are educational and simplified. They are not legal advice and do not replace the text of the regulation or guidance from your regulatory authority or counsel.
- 21 CFR Part 111
- Current Good Manufacturing Practice in Manufacturing, Packaging, Labeling, or Holding Operations for Dietary Supplements. Covers personnel, physical plant, equipment, production and process controls, the quality control unit, records and returned products.
- 21 CFR Part 117
- Dietary supplement operations in compliance with Part 111 are subject to modified requirements under Part 117 — the preventive controls subparts generally do not apply, but Subpart B CGMPs and other provisions may. Applicability should be confirmed for your specific operation.
- 21 CFR Part 101 (Subpart F and related)
- Supplement Facts labeling, ingredient declaration and structure/function claim requirements. Label review is a distinct exercise from cGMP compliance and often needs both regulatory and legal input.
- Serious adverse event reporting (DSHEA / 21 U.S.C. 379aa-1)
- Responsible parties for dietary supplements have serious adverse event reporting obligations and associated recordkeeping. A written procedure and a designated owner should exist before you need them.
Applied by industry
How this looks in practice.
The same regulatory framework produces very different programs depending on the operation it lands in.
- Dietary Supplement ManufacturersPart 111 is built on written specifications and a quality unit with real authority. Most findings trace to a specification that was never established or data that never reached the batch record.
- Private Label BrandsYour name is on the package and someone else's plant made it. Oversight of the co-manufacturer is the whole job, and a certificate on file is not oversight.
- StartupsDecisions made in the first six months — formulation, process, co-packer, label — set your compliance cost for years. Most of them are cheaper to get right than to fix.
- DistributorsDistributors rarely create hazards, but they decide whether one spreads or stops. Receiving discipline and lot-level traceability are the two controls that matter most.
- ImportersAs the FSVP importer you answer for hazards created in facilities you do not control. FSVP inspections are records inspections — and the file has to be producible on request.
Questions we get asked
Dietary Supplements — common questions
Our contract manufacturer holds the cGMP responsibility, so are we covered?
Not entirely. Part 111 applies to those who manufacture, package, label or hold dietary supplements, and a brand owner that holds product or performs labeling can fall within scope. Beyond the regulation, you carry commercial and reputational exposure for what is in the bottle and what the label says. We help brand owners build a real qualification and oversight file for their manufacturers rather than relying on an annual certificate.
Can we skip identity testing if we have a certificate of analysis?
Part 111 requires at least one appropriate test or examination to verify the identity of a dietary ingredient, and that particular requirement is not satisfied by a supplier certificate alone. For other component specifications, documented reliance on a certificate of analysis is possible where you establish the reliability of the supplier's analysis and confirm it periodically. The distinction is a frequent source of observations.
What does audit preparation actually involve here?
We pull a sample of executed batch records and trace them backwards — component receipt, identity testing, specification, master record, deviations, reconciliation, finished testing, quality unit signature, distribution. Anything that cannot be reconstructed becomes a finding to close before the audit rather than during it.

FDA & FSMA Compliance
The FDA Food Safety Modernization Act moved the regulatory burden from reacting to contamination to proving you prevented it. We build the hazard analysis, preventive controls, supplier verification and records systems that carry that burden — and we prepare your team for the inspection that tests them.

A HACCP plan is only worth what its critical limits can be defended with. We develop, rebuild and independently review plans across seafood, juice, retail and specialized processes — including the variance and validation documentation that regulators ask for first.

Preventive controls only work when the programs beneath them do. We build and audit the prerequisite layer — sanitation, environmental monitoring, allergen segregation, food defense, supplier approval — and the CAPA discipline that keeps findings from repeating.
