Answer

7 capsule manufacturers in IR's directory carry an independently confirmed third-party certification and accept work from emerging supplement brands. 3 of the 7 (Makers Nutrition, SMP Nutra, Vitaquest International) publish both MOQ floors and lead times: a disclosure pattern the 4 others have not adopted. Method, scoring, and per-vendor limitations are disclosed below.

§3Frequently asked

Why is Makers Nutrition ranked first instead of Robinson Pharma?

IR's score weights public commercial transparency (35 of 100 points) alongside confirmed certifications (50 of 100). Makers Nutrition publishes both its MOQ floor (500 to 1,500 bottles) and lead time (4 to 6 weeks). Robinson Pharma publishes neither, despite operating at the largest softgel production scale in the United States. MOQ opacity costs Robinson Pharma 35 transparency points.

What does "Not publicly disclosed" mean?

It means IR could not find the data point on the manufacturer's website, in a public regulatory filing, or in a third-party industry directory. It does not mean the manufacturer refused a quote. Buyers should request MOQ and lead-time confirmation directly during initial inquiry. IR does not synthesize plausible-looking numbers when public evidence is absent.

How often is this list updated?

Quarterly review with event-triggered updates on FDA enforcement action, change in confirmed certification status, or material business change (acquisition, ownership transfer, facility closure). Last full review: April 25, 2026. Last claim re-verification: July 7, 2026.

Why aren't there more manufacturers on this list?

IR's directory contained 112 capsule-capable contract manufacturers at the April 2026 review (the live directory count on this page updates as the directory grows). The seven profiled here met the April 2026 inclusion criteria: active capsule capability, one or more certifications confirmed against a public registry, and FDA registration (legally required of every facility; vendor-represented, since registration has no public lookup). Qualifying additions are evaluated at the next full review. We list only what we can substantiate.
