Questions buyers ask
Who owns a custom supplement formula?
It depends on the contract. Some manufacturers transfer the formula to you; others keep it, which can make it harder to move production later. Ask before development starts and get the answer in writing, along with development fees, sample rounds and timelines.
Do you verify that these companies offer custom formulation?
No. A company is listed here when one of its facilities is on a public registry we check and its own website says it offers custom formulation. We keep the quote, the page and the date we checked, and show them on the company’s profile. The registry certification is checked by us; the claim is the company’s own, so confirm it with the manufacturer before you rely on it.
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.
