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.

Excluded: Self-only operations (no contract manufacturing) · Active FDA warning letter or unresolved enforcement · Insufficient public documentation to verify capabilities · Manufacturers without any independently confirmed certification.
Data sources: NSF International public directory (info.nsf.org) · SQFI Certified Site Directory · USDA Organic Integrity Database (organic.ams.usda.gov) · FDA establishment registration database · vendor self-reports cross-checked against public records.
Scoring weights: Independent third-party certification (max 50): NSF GMP +30 · NSF/ANSI 455-2 +30 · SQF +20 · USDA Organic +15 · NSF Certified for Sport +15. Public commercial transparency (max 35): published MOQ +18 · published lead time +17. Editorial disclosure discipline (max 15): material connection statement +5 · ownership or backing disclosure +10.
Commercial disclosure: None of the seven manufacturers paid for placement. Commercial status (Basic / Enhanced) and editorial status (Source-checked / Assessed) are independent axes. See how we assess.
Refresh: Quarterly · event-triggered on FDA enforcement action or material change in confirmed certification status.

Cited findings

All seven hold ≥1 independently confirmed certification cross-checked against a public directory (NSF, SQFI, USDA Organic, or NSF/ANSI 455-2). Three hold two confirmed certifications.
Three of seven publish MOQ floors and lead times on their websites (Makers Nutrition, SMP Nutra, Vitaquest International). The four others require a quote request.
Captek Softgel International is the only vendor with both NSF GMP (NSF 306) and SQF Certified status independently confirmed against public directories. The redundancy signals process maturity.

#	Manufacturer	Location	MOQ	Lead time	Confirmed certs	IR score	One real limitation
1	Makers Nutrition	Commack, New York	500 to 1,500 bottles	4 to 6 weeks	NSF GMP	70	On-site facility inspection was not conducted. Financial stability and insurance coverage have not been independently assessed.
2	SMP Nutra	Largo, Florida	1,000 bottles (stock), 1,500 to 2,000 bottles (custom)	6 to 8 weeks (stock products)	NSF/ANSI 455-2	70	Lead times for fully custom manufacturing are not published. Stock products may use shared formulations across multiple brands.
3	Vitaquest International	West Caldwell, New Jersey	4,100+ bottles (varies by format)	12 to 16 weeks	NSF GMP	70	MOQ floor (4,100+ bottles) and lead time (12 to 16 weeks) make this a poor fit for emerging brands. USP Verified status was claimed but not found in the USP Verified Products directory as of March 2026.
4	Captek Softgel International	Cerritos, California	Not publicly disclosed	Not publicly disclosed	NSF GMP, SQF	65	Specific MOQ and lead times are not publicly disclosed for custom orders. Limited to softgels, gummies, and capsules; no tablet or powder capability.
5	Kelker Pharma	Riverside, California	Not publicly disclosed (website states "low minimums")	Not publicly disclosed	NSF/ANSI 455-2, USDA Organic	45	FDA establishment registration could not be located in the FDA database. Company also operates its own consumer brand (NUTRILINQ), which may create capacity allocation considerations during high-demand periods.
6	Robinson Pharma	Santa Ana, California	Not publicly disclosed	Not publicly disclosed	SQF, USDA Organic	40	MOQ floor not publicly disclosed and likely high given production scale. NSF and USP Verified certifications were searched in their respective public directories and not found as of March 2026, despite vendor self-report.
7	GMP Laboratories of America	Anaheim, California	Not publicly disclosed	Not publicly disclosed	NSF Certified for Sport, USDA Organic	30	FDA Drug Establishment registration number (FEI) not publicly available for independent verification. Material connection or backing disclosures not populated. Three terminated voluntary recalls between 2009 and 2025 (one Class II, two Class III downstream).

§3Frequently asked

Does paid placement affect rank?

No. None of the seven manufacturers in this list paid for placement. Commercial status (Basic or Enhanced) and editorial status (Source-checked or Assessed) are independent axes on IR's directory. See how we assess. The transparency-weighted score is computed from public evidence: confirmed certifications, published MOQ and lead time, and disclosure discipline.

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. Next scheduled refresh: July 25, 2026.

Why aren't there more manufacturers on this list?

IR's directory contains 45 capsule-capable contract manufacturers. Seven met the inclusion criteria for this assessed list: FDA-registered, active capsule capability, and at least one independently confirmed third-party certification verified through a public directory. The remaining 38 either lacked a confirmed certification at review time or are pending re-verification. We list only what we can substantiate.

Limitations

Inclusion is based on at least one independently confirmed third-party certification at review time. Self-reported certifications were not counted toward the score even when widely cited; this prevents the most common attribution error in the supplement industry: repeating a vendor's claim as an independent fact.
MOQ and lead time are recorded as published on each manufacturer's website. Buyers should confirm both in writing during initial inquiry; quoted ranges shift with raw material availability, formulation complexity, and production calendar.
On-site facility inspections were not conducted for any of the seven. Editorial assessment is at the source-checked level (single-pass public-record verification), not the assessed level (deep-dive inspection plus document review).
FDA enforcement history was reviewed for active warning letters but not exhaustively for historical 483 observations. Buyers conducting their own due diligence should query the FDA inspection database directly and request a copy of any observation responses.
The transparency-weighted score is one signal, not a recommendation. A manufacturer with a higher score may still be a poor fit for a specific formulation, dosage form, or volume tier. Use the per-vendor strength and limitation as the operational read.
