Facility Certifications
These programs audit manufacturing facilities and quality systems. They verify how products are made, not what is in a specific product. A facility certification is the foundation: cGMPcGMP (Current Good Manufacturing Practice)FDA's mandatory quality standards for supplement manufacturing facilities. compliance is a legal requirement (21 CFR Part 111), but third-party verification through programs like these provides independent confirmation.
| Program | Issuing body | Scope | Public database | Amazon | IR listings |
|---|---|---|---|---|---|
| NSF GMP Registration | NSF International | Facility practices, quality systems, production controls for dietary supplements | Searchable → | TIC + Fast-Track | 29 |
| NPA GMP Certification | Natural Products Association | Third-party GMP audit specific to natural products manufacturing | None | Not listed | 3 |
| SQF Certification | Safe Quality Food Institute (SQFI/FMI) | Food safety and quality management. Three levels: fundamentals, food safety, food safety + quality. | Searchable → | Not listed | 12 |
Product Verification Programs
These programs verify specific products, not entire facilities. They test what is actually in the bottle: active ingredients, contaminants, or banned substances. Product certifications are especially important for brands selling through channels with strict compliance requirements or targeting athletes.
| Program | What's tested | Substances | Sample source | Amazon Fast-Track | IR listings |
|---|---|---|---|---|---|
| USP Verified Mark | Identity, potency, purity, contaminants, manufacturing practices | Full contaminant panel | Manufacturer-submitted with on-site verification audits | Yes | 2 |
| NSF Certified for Sport | Banned substances (WADA list), label claims, contaminants, facility audit | 280+ banned substances | Manufacturer-submitted with ongoing lot testing | Yes | 9 |
| BSCG Certified Drug Free | Banned substances, label claims, selected contaminants, GMP review | 500+ prohibited substances | Manufacturer-submitted with every-lot testing | Yes | — |
| Informed Sport / Informed Choice | Banned substances (WADA list), contaminants | 200+ banned substances | Manufacturer-submitted with blind sample testing | Yes | — |
| TESTED by SuppCo | Active ingredient verification against label claims | Active ingredients per label | Anonymous off-shelf purchase from brand website | No | — |
What This Comparison Shows
Facility vs. product: most brands need both
A facility certification (like NSF GMPNSF InternationalIndependent third-party organization that tests and certifies supplement manufacturing facilities and products.) confirms your manufacturer follows quality practices. A product certification (like USP VerifiedUSP (United States Pharmacopeia)Independent scientific organization that sets quality standards for medicines and supplements.) confirms a specific product meets testing standards. These are complementary, not interchangeable. A facility can pass a GMP audit while individual products have label accuracy issues, and a product can pass potency testing while the facility has quality system gaps.
Sample source matters for credibility
How a program obtains its test samples shapes the credibility of results. Most established programs (NSF, USP, BSCG, Informed) test manufacturer-submitted samples, sometimes with additional verification through on-site audits or blind testing. TESTED by SuppCo purchases products anonymously from brand websites, which means the tested product is the same one a consumer would receive. Both approaches have trade-offs: manufacturer submission enables consistent lot-by-lot tracking, while anonymous purchase tests what actually reaches the market. The question for brand owners is which model better serves their credibility story.
Amazon compliance is reshaping certification decisions
Amazon now requires all dietary supplement sellers to demonstrate cGMPcGMP (Current Good Manufacturing Practice)FDA's mandatory quality standards for supplement manufacturing facilities. compliance through an approved third-party Testing, Inspection, and Certification (TIC) organization. Sellers have 90 days to comply once contacted. Separately, Amazon's Compliance Fast-Track program automatically validates products certified by partner organizations (BSCG, Clean Label Project, GRMA, Informed, NSF, and USP as of March 2026), eliminating manual documentation submission. For brands selling on Amazon, a Fast-Track-eligible certification reduces compliance friction. For a detailed overview, see our Amazon supplement compliance guide.
Key Limitations by Program
Every certification program has boundaries. Understanding what a program does not cover is as important as knowing what it does.
NSF GMP Registration: Facility-level only. Does not test individual products. 'Registered' vs 'Certified' distinction matters: registration is the base level.
NPA GMP Certification: Less widely recognized than NSF GMP. No public verification database. NPA is a trade association that both advocates for and certifies the industry.
SQF Certification: Food industry standard, not supplement-specific. Does not replace supplement-specific cGMP (21 CFR Part 111). Level 2 is 'Food Safety' only; Level 3 adds quality.
USP Verified Mark: Product-specific, not facility-wide. A company may have one USP Verified product while others are not. Fewer than 2% of supplements carry this mark.
NSF Certified for Sport: Product-specific, not facility-wide. Only certified SKUs are covered. Required by USADA, MLB, NHL, CFL. Primarily relevant for sports nutrition products.
BSCG Certified Drug Free: Primarily focused on banned substance screening for sports and athletic products. Founded by the family that pioneered Olympic drug testing.
Informed Sport / Informed Choice: Two tiers: Informed Sport (monthly batch testing, stricter) and Informed Choice (biannual, broader). Recognized by many international sports organizations.
TESTED by SuppCo: Newest program (launched March 3, 2026). 10 initial partner brands. 95% active ingredient threshold. Tests label accuracy, not banned substances. All results published including failures.
Other Programs Worth Knowing
ConsumerLab.com: Independent testing organization that purchases and tests supplements, publishing results for paying subscribers. Offers an Approved Quality seal. Consumer-facing (not a B2B brand certification), but passing ConsumerLab testing is a meaningful quality signal.
USDA Organic: Regulatory certification (not voluntary industry program) for products meeting USDA National Organic Program standards. Covers ingredient sourcing and processing, not supplement-specific quality or potency.
International programs: HASTA (Australia), Cologne List (Germany), and Health Canada's NPN system serve specific markets. Brands exporting internationally should check destination-country requirements.
What This Comparison Does Not Show

Frequently Asked Questions
What is the difference between facility certifications and product certifications?
Facility certifications verify that a manufacturing facility follows quality practices (how products are made). Product certifications verify that specific products meet testing standards (what is in the bottle). Most brands benefit from at least one of each, but the right combination depends on your products, distribution channels, and target market.
Do I need a certification to sell dietary supplements?
No. FDA facility registrationFDA Facility RegistrationMandatory registration of food/supplement manufacturing facilities with FDA. and cGMPcGMP (Current Good Manufacturing Practice)FDA's mandatory quality standards for supplement manufacturing facilities. compliance (21 CFR Part 111) are legal requirements, not voluntary certifications. Third-party certifications are voluntary but increasingly required by retailers. Amazon now requires third-party cGMP verification for all dietary supplements sold on its marketplace.
Which certifications qualify for Amazon's Compliance Fast-Track?
As of March 2026, Amazon's Compliance Fast-Track partners for dietary supplements include BSCG, Clean Label Project, GRMA, Informed, NSF, and USP. Products certified by these partners get automatic Amazon compliance validation, eliminating the need to submit separate documentation.
How do I know if a certification program uses independent testing?
Check the sample source. Most established programs test manufacturer-submitted samples, sometimes with additional verification through on-site audits or blind testing. TESTED by SuppCo purchases products anonymously. Both approaches have trade-offs. See the product verification table above for program-specific details.
