USP <2750>

USP General Chapter <2750> Manufacturing Practices for Dietary Supplements is the United States Pharmacopeia's compendial chapter applying pharmaceutical-style GMP principles to dietary supplement manufacturing, calibrated for the supplement context. It covers personnel qualification and training, premises and equipment (design, qualification, cleaning, calibration), control of components and contact materials with explicit reference to USP-NF monographs where they exist, control of operations (master manufacturing records, batch production records, in-process controls), quality control unit responsibilities, finished-product testing and release, holding and distribution (including reserve samples), returned and salvaged supplements, complaints and records.

21 CFR 111 is the FDA legal minimum; <2750> sits above it as voluntary best practice with the compendial bar. The chapter integrates with related USP general chapters — <231>/<232>/<233> (heavy metals), <61>/<62>/<2021>/<2022> (microbiology), <1010> (analytical data interpretation), <1058> (analytical instrument qualification), <1224> (transfer of analytical procedures), <2040> (disintegration and dissolution) and <2091> (weight variation). The recurring 21 CFR 111 to <2750> gaps a real assessment exposes: USP-NF monograph linkage on each ingredient (not just supplier COA), formal IQ/OQ/PQ equipment qualification, stability programme with stability-indicating methods, OOS investigations aligned to USP <1010>, reserve sample retention per lot, and validated cleaning.

<2750> becomes operative when the product carries USP marks (USP Verified, USP-NF), when it is investigational supply for an IRB-approved clinical trial, when the brand sells through practitioner channels (naturopathic, integrative, functional medicine), when sports certification (NSF Certified for Sport, Informed-Sport) requires it as a baseline, and when hospital and long-term-care formularies use it as a procurement filter. The USP Dietary Supplement Verified Programme operationalises the chapter through site audit, product testing against USP compendial methods, and ongoing surveillance — the Verified mark on the label is the visible end-state. In V5 the <2750> control set, USP-NF monograph references per ingredient, IQ/OQ/PQ records, stability programme, OOS investigations and USP Verified surveillance schedule live on one SKU spine.
