Questions buyers ask
How are supplement packaging companies selected?
Companies qualify through a packaging facility in the registry data we check or a packaging and bottling claim on their website. All also have a registry-listed manufacturing or packaging facility. A website claim is not verified by us. Check the facility record and confirm your format with the company.
What is supplement co-packing?
A co-packer packages products for another brand, for example bottling finished bulk capsules or filling powder into pouches. Packaging does not necessarily include making the formula; agree who supplies the bulk product and who handles testing and release.
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.
