Dietary supplement quality and cGMP readiness consulting

The Work

21 CFR Part 111 is the cGMP rule for dietary supplements, and it is exacting. It governs identity, purity, strength, and composition; specifications across components, in-process material, and finished product; the records that prove each batch met them; and the responsibilities that sit with the manufacturer and with the brand owner who put the product into commerce. Many brand owners do not manufacture themselves, and assume that responsibility rests with the contract manufacturer. The rule does not work that way. Importers carry their own obligations on top. A specification gap, a label-claim misalignment, or an unclear responsibility split typically does not show up at formulation. It shows up at audit, at retailer onboarding, or at a recall.

RGM provides senior judgment on where the supplement program actually stands against 21 CFR Part 111, where the gaps are, and what closing them looks like in practice. The work draws on decades of operating experience leading regulatory, quality, and commercialization strategy across dietary supplements and consumer healthcare.

What's typically included

  • 21 CFR Part 111 gap assessment — structured review of the brand's quality system, specifications, records, and supplier oversight against the cGMP rule, with the most material gaps prioritized.
  • Specification review — senior read on component, in-process, and finished-product specifications, and whether they actually tie the formulation, the label, and the testing together.
  • Label claim alignment — checking that what the label says is what the specifications and release testing actually support.
  • Importer / manufacturer responsibility mapping — clarifying which obligations sit with the brand owner, which sit with the contract manufacturer, which sit with the importer, and where the current arrangement leaves a gap.
  • Launch-readiness check — quality and documentation readiness against retailer expectations and audit exposure before the product ships.

When this is the right conversation

Brand owners typically engage RGM here when a supplement is moving toward launch and quality readiness has not been independently reviewed; when an importer is bringing a foreign-manufactured product into the U.S. and the responsibility split needs to be made explicit; when a retailer audit or quality questionnaire has surfaced gaps; or when a 483, warning letter, or recall in the category has prompted leadership to want an outside read on its own exposure.

Output you can use

A prioritized 21 CFR Part 111 gap assessment with the material findings called out, a documented view of where specifications and label claims line up and where they don't, a responsibility map that names what sits with the brand, the manufacturer, and the importer, and a practical readiness recommendation for launch. Written so it can drive quality investment decisions at the leadership table.
