Registry check · PQQ
Does anyone independently verify PQQ supplements?
Not one of these 4 products is listed by NSF, USP or Informed Sport as a verified product. Yet 1 of them advertise “third-party testing” without naming the certifier that did it — wording no public registry can confirm or deny. A factory-level claim such as “cGMP” audits the plant, not the PQQ bottle you would actually receive.
This is the group the audit found most exposed: 14 of the 17 newer supplements we track have no certified option at all. Every one of the 8 established nutrients checked — B12, omega-3, vitamin D among them — has one. Demand for PQQ arrived before verification did.
4 checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What 4 PQQ labels show
Priced per day, these PQQ products run $0.30 to $0.98 — a 3.3× gap between the cheapest and dearest PQQ here, across 4 brands.
Servings here are close enough to compare directly, so the gap is a real one: Nutricost at $0.30 buys the same thing as Jarrow Formulas at $0.98.
All PQQ Supplements Compared
PQQ is unusually simple to compare: essentially every product in the Verified Supplement Data catalog is standardised to 20 mg per serving, which is the dose used in the human research, so cost per day is a genuinely like-for-like comparison here. That makes this one of the few categories where the cheapest row really is the best value. PQQ is frequently bundled with CoQ10 at a premium — buying them separately is usually cheaper.

The shelf · PQQ
The PQQ shelf is unusually consistent
Across 4 products from 4brands, the cheapest day is Nutricost PQQ 20 mg at 30¢ and the dearest Jarrow Formulas PQQ 20 mg at 98¢ — a gap of 3.3×, where categories on this site routinely run 15× or worse. With PQQ priced this tightly, the 4-brand question of who will verify their contents decides more than the price column does.
Method: the 4 PQQ products above, compared on label facts — serving size, servings per container, form, price. Not a dosing recommendation.
Evidence gap · PQQ
Nobody has pooled the PQQ research yet
40 human papers name PQQ in the title , and 1 of those are randomised controlled trials. Zero are systematic reviews or meta-analyses. A review is what pools small trials into one estimate, so with 1 trials and no review, every PQQ claim you meet rests on studies nobody has weighed against each other.
With 1 trial to pool, a PQQ review is not close. That is not evidence it fails; it is the absence of evidence either way.
Method: PubMed counts for pqq in the title, human studies, and the same search filtered to systematic reviews and meta-analyses. Run the searches yourself — the counts move as papers publish, and this claim is only as current as the day it was checked.
How these 4 PQQ products were ranked
Not one of these 4 PQQ products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever PQQ you buy. Full methodology.
