Third-party tested supplement database
Quick answer
138 of the 1158 supplements we track (11.9%) are individually listed by NSF, USP Verified or Informed Sport. Another 259 come from a brand with some certified product but no listing for that one, and 761 come from brands absent from all three registries. The cheapest certified product per day of its studied dose is Nature Made Iron 65 mg at $0.020.

Not medical advice. This database checks products against public certification registries and the brands’ own published lab reports; we do not test products ourselves. Matching is by name and is deliberately generous, so it overstates certification rather than understating it: some matches are a different product from the same brand. Confirm the exact product on the certifier’s own page before relying on a row.
Safety: some products listed here give more than the adult upper limit in one serving: vitamin D4,000 IU a day; iodine1,100 mcg a day; manganese11 mg a day; preformed vitamin A (retinol)10,000 IU a day; iron45 mg a day (NIH). Do not take more than that unless your doctor tells you to.
Search every product
Type a brand, product or category. Listed means a product with this name is on a testing list (confirm the exact product on the list’s own site); brand only means the brand has at least one listed product but not this one; not listed means the brand is on none of the three lists. Cost is per day of the dose the category’s trials used, in USD.

Oil of oregano is not in this table either. We checked 9 oregano oils, softgel and drops, against the same five registries and found none listed; see the best oil of oregano, compared by price per 100 mg and carvacrol.
What each mark actually checks
- NSF/ANSI 173 (and NSF Certified for Sport): facility audit, label-claim testing of production lots, contaminant screening; the Sport mark adds a screen for banned substances on every lot. Listed products are searchable by name on info.nsf.org.
- USP Verified: the product contains the labeled ingredients at the labeled amounts, without harmful contaminant levels, dissolves as specified, and is made to FDA cGMP; the USP mark is on the bottle and the product on quality-supplements.org. Only 16 brands hold it.
- Informed Sport / Informed Choice: every batch (Sport) or periodic batches (Choice) tested for banned substances by LGC; strong on doping risk, silent on whether the dose matches the label.
- IFOS (fish oil only): lot-level EPA/DHA content, oxidation and contaminant testing by SGS Nutrasource with a public report per lot.
- “Third-party tested” on a label with no program named: unverifiable. Ask the brand for a certificate of analysis with a lot number and a named lab; 12 of the 123 products we checked in depth actually publish one.
Frequently asked questions
What does "third-party tested" actually mean on a supplement label?
Four different things, and only two can be checked. (1) Certified: the product is listed by an independent program — NSF/ANSI 173 or NSF Certified for Sport, USP Verified, Informed Sport/Choice — which audits the facility and tests production lots. (2) Lot report: the brand publishes a certificate of analysis for the lot you can buy, from a named lab. (3) A report with no lot number, or a lab the brand will not name. (4) The phrase "third-party tested" on the label with nothing behind it. Of the 1158 products here, 138 are (1); 12 of the 123 we checked in depth publish a lot-specific report.
How many supplements are third-party certified?
In our catalogue, 138 of 1158 (11.9%) are individually listed by NSF, USP or Informed Sport. The three registries together hold 5,317 listings as of Tuesday, August 25, 2026; most of the market is not in any of them.
Which supplement brands are third-party tested?
Brands with the most individually certified products in our catalogue: Thorne (33 of 44), Nature Made (19 of 34), BulkSupplements (7 of 43), Transparent Labs (6 of 8), Klean Athlete (5 of 8), Garden of Life (4 of 13), Momentous (4 of 13), Sports Research (3 of 25). A brand being in a registry does not mean every product is: 259 products here come from a brand with some certified product but no listing for that product.
Is a Health Canada NPN or an FDA-registered facility the same as third-party testing?
No. An NPN is a Canadian sale licence and "FDA-registered facility" means the factory is registered, not inspected per lot. cGMP audits the process, not the bottle. Only a product-level registry listing or a lot-specific certificate of analysis tells you a lab looked at what you are buying.
What is the cheapest third-party certified supplement?
Per day of the studied dose, the cheapest certified product we track is Nature Made Iron 65 mg at $0.020 per day (USP Verified, Iron sulfate).
How do I check a product myself?
Search the product name on info.nsf.org (Certified Dietary Supplements), quality-supplements.org (USP Verified) and sport.wetestyoutrust.com (Informed Sport). Match the exact product and flavour, not just the brand. Then look for a certificate of analysis on the brand site with a lot number that matches your bottle and a named, accredited lab.
Products that publish a lot-specific report
The strongest evidence short of a registry listing: a certificate of analysis for a numbered lot from a named laboratory. 12 products we checked publish one.
