Third-party tested supplement database

By Erin Rose · Registries as of Tuesday, August 25, 2026 · Index rebuilt October 9, 2026 · Methodology

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.

Quick answer

122 of the 1073 supplements we track (11.4%) are individually listed by NSF, USP Verified or Informed Sport. Another 239 come from a brand with some certified product but no listing for that one, and 712 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 $0.030.

Search every product

Type a brand, product or category. Registry name match means a product with this name appears in a registry (confirm the exact product on the certifier’s page); brand only means the brand has at least one certified product but not this one; absent means the brand is in none of the three registries. Cost is per day of the dose the category’s trials used, in USD.

Mushroom coffee is not in this table yet. We checked 12 mushroom coffees against the same registries and found none listed; see mushroom coffees compared by cost per cup.

Black seed oil is not in this table either. We checked 9 black seed oils, liquid and softgel, against the same five registries and found none listed; see the best black seed oil, compared by price per gram and thymoquinone.

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 labelled ingredients at the labelled 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 1073 products here, 122 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, 122 of 1073 (11.4%) 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 (29 of 35), Nature Made (13 of 31), BulkSupplements (7 of 41), Transparent Labs (6 of 8), Garden of Life (4 of 12), Klean Athlete (4 of 5), Sports Research (3 of 26), Optimum Nutrition (3 of 13). A brand being in a registry does not mean every product is: 239 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 $0.030 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.
