Questions buyers ask
What is a dietary supplement contract manufacturer?
A contract manufacturer produces supplements that another company sells under its own brand. Some offer custom formulation and development; others mainly run your formula or offer stock (private label) formulas you can put your label on. Many also handle packaging, labelling and testing.
What does NSF/ANSI 455-2 certification mean?
NSF/ANSI 455-2 is a good manufacturing practice (GMP) audit standard for dietary supplements. It is built around the US FDA’s dietary supplement GMP rule (21 CFR Part 111) and adds retailer-driven requirements, so facilities are audited against one harmonised checklist. Certification applies to a specific facility and is listed publicly by the certifier.
What should I ask for in a quote request?
Ask for minimum order quantity, lead times, formulation options, testing and certificates of analysis, in writing. In detail: ask about minimum order quantity (MOQ) per SKU, lead time for a first run and for reorders, whether they offer stock formulas or custom formulation, who sources raw materials, what testing they run (identity, potency, microbiological, heavy metals) and whether you receive a certificate of analysis (COA) per batch, and whether they support the label claims you plan to make. Terms vary widely by manufacturer, so compare written answers rather than assumptions.
How do I verify a manufacturer’s GMP certification myself?
Ask the manufacturer for their current certificate and the exact facility address it covers, then look that facility up on the certifier’s public listing (for NSF/ANSI 455, NSF’s online listings). Certificates apply to specific sites, so make sure the facility that will make your product is the one listed. Each profile here links to the public listing we checked and the date we checked it.
Why is a manufacturer missing from this list?
A manufacturer is missing when none of its facilities appears on NSF’s public NSF/ANSI 455 listing, the only registry this directory checks today. Many good manufacturers hold other GMP certifications (or an FDA-registered facility without third-party certification) and are not listed yet. We plan to add other registries; manufacturers can also ask to be listed.
