Questions buyers ask
How do I choose a vitamin manufacturer in the USA?
Start with the USA list, check the exact facility and its certificate scope, and confirm private label vitamins and minerals. Ask for the minimum order, first-run and reorder lead times, testing plan and an itemized quote. Website capabilities are company claims unless a separate registry basis is shown; confirm the proposed work directly.
What should I ask a vitamin manufacturer?
Ask which forms of each vitamin and mineral they can source, how they set overages (extra ingredient so the label amount holds until expiry), whether they test potency at the end of shelf life, and which dosage forms they make in-house. Get MOQ and lead time in writing.
Do you verify that these companies make vitamin and mineral products?
No. A company is listed here when one of its facilities is on a public registry we check and either its USDA Organic certificate lists vitamin or mineral items or its own website says it makes vitamin and mineral products. The USDA Organic item list is the certifier’s record of what the operation is certified to handle organically, as we found it in the USDA Organic Integrity Database on the date shown; it covers organic items only and is not a test of any product. A website claim is the company’s own statement: we keep the quote, the page and the date we checked. Each card says which applies. Confirm either 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.
