Updated . Paid Featured listings have no effect on this list.
How we built this list
We considered the 156 custom supplement manufacturers we list in the USA. A company is on the list only when all five of these hold:
- It holds an active GMP certification or licence on a public registry we check. Informed Manufacturer alone does not count; it is not a GMP audit.
- It lists a company website.
- FDA inspections are matched to it, and the latest one ended on or after November 1, 2021 (the last 5 years) and was classified No Action Indicated (NAI).
- No matched FDA inspection, ever, was classified Official Action Indicated (OAI).
- No matched FDA recall, ever, was Class I.
Membership in this list also requires the company’s own website to say it offers custom formulation; that part is the company’s claim, not a record we verified. How we collect website claims
Order: most independent registries listing the company’s active certifications first; then fewest recalls matched in FDA data; then most FDA inspections with no action indicated since November 1, 2021; then the most recent inspection; then name, A–Z. Featured status is not an input.
Sources: FDA Data Dashboard (inspections; FDA inspection data as of October 22, 2026), openFDA food enforcement reports (recalls; FDA recall data as of October 27, 2026) and the public listings of NSF/ANSI 455-2, Informed Manufacturer and USDA Organic (certifications; each profile shows its check date).

What this list doesn’t tell you
- Public records are matched to companies by name and address, so a record can be missed or matched to a related company. Each profile shows the records we matched.
- It says nothing about price, minimum order, lead time or service.
- A company missing from it may simply have no FDA inspection we could match. That is not a judgment of the company.
Before you choose, verify the manufacturer’s certification yourself and ask the questions that matter for your product.
Questions buyers ask
Who is the best custom supplement manufacturer in the USA?
No single custom supplement manufacturer is best for every product. Of the 156 custom supplement manufacturers we list in the USA, 34 meet all five public-record criteria below; ranked by those records, the top three are Catalyst Nutraceuticals, Vitaquest International and Lonza Greenwood LLC. The right manufacturer for you depends on your formula, dosage form, order size and budget, which public records don’t cover.
Which custom supplement manufacturers do you recommend?
We don’t endorse or recommend any manufacturer. This list only shows which companies meet public-record criteria: an active GMP certification or licence, a website, a latest FDA inspection with no action indicated, no FDA inspection classified Official Action Indicated, and no Class I recall. Compare written quotes from several of them and confirm each certification on the certifier’s own listing before you choose.
How did you choose these manufacturers?
A company is on the list when it holds an active GMP certification or licence on a public registry we check, lists a website, has FDA inspections matched to it whose latest ended within the last 5 years and was classified No Action Indicated, has no matched inspection ever classified Official Action Indicated, and has no matched Class I recall. Qualifying companies are ordered by the number of independent registries that list their certifications, then by the fewest recalls matched in FDA data, then by FDA inspections with no action indicated in the last 5 years, then by the most recent inspection, then by name.
Can a manufacturer pay to be on this list?
No. Featured listings are paid placement on directory pages and have no effect here. Featured status is not an input to this list; who qualifies and in what order comes only from public records.
Why isn’t a company I know on the list?
It may not meet one of the criteria, or we may not have matched its records. We match FDA inspections and recalls to companies by name and address, and a company with no matched FDA inspection cannot qualify, so a missing company is not a judgment of it. Only the 156 custom supplement manufacturers we list in the USA are considered; manufacturers can ask to be listed.
How often is the list updated?
The page is regenerated daily. This version uses FDA inspection data as of October 22, 2026 and FDA recall data as of October 27, 2026; each profile shows when we last checked the company’s certifications.
