Questions buyers ask

How do I choose a vegan supplement manufacturer in the USA?

Start with the USA list, check the exact facility and its certificate scope, and confirm ingredients, processing aids and any product certification. 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.

How do I check a manufacturer’s vegan claim?

Ask whether they hold a vegan certification and from which programme, which products and facility it covers, and how they keep animal-derived ingredients such as gelatin apart on shared lines. Then check the certificate with the programme that issued it.

Do you verify that these companies can make vegan products?

No. A company is listed here when one of its facilities is on a public registry we check and its own website says it can make vegan products. 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.

How do I compare vegan supplement manufacturers in California?

Check the facility address and the scope shown on its registry record, then confirm that the proposed work will take place at that site in California. Ask for a written quote with minimum order, testing, packaging, freight and lead times. A company address alone does not establish where your order will be made.
