Is PQQ legal in the United States?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
PQQ can be sold in the United States as a supplement or cosmetic ingredient, classified as "Sold as a supplement". That is not drug approval: FDA has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 4 human studies are cited on its profile.

What PQQ is
Sold for mitochondrial biogenesis. In a six-week training study, PQQ raised PGC-1alpha protein more than placebo and changed aerobic performance not at all, and a study in human keratinocytes and fibroblasts found no increase in mitochondrial biogenesis at all.
PQQ is a redox-cycling quinone found in trace amounts in foods and sold as a supplement, most often as the disodium salt. The marketing claim is specific and testable: that it triggers mitochondrial biogenesis through PGC-1alpha, effectively growing new mitochondria.
Mechanism: A redox cofactor that cycles between oxidised and reduced states and can act as an antioxidant and as a signalling molecule. The proposed route is activation of AMPK and upregulation of PGC-1alpha, the transcriptional coactivator that drives mitochondrial biogenesis, which has been shown in a rotenone rodent model of Parkinson's disease and in mouse work.
Regulatory history: Sold as a dietary supplement in the United States. Not an approved drug for any indication anywhere.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for PQQ at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
