Pyrroloquinoline quinone (PQQ)
Mitochondria & Cellular Energy · Mitochondrial biogenesis cofactor
Tier B-
Bottom line
Read Off Label grades Pyrroloquinoline quinone (PQQ) as B- (6.2/10) based on weak-moderate evidence, low-moderate benefit magnitude, and a low-risk safety profile.
Popular in mitochondrial-focused biohacker stacks (often paired with CoQ10 and Urolithin A).
Typical use: 10-20 mg/day; some products use BioPQQ or MitoQuinone-branded forms — OTC.
What this is
Popular in mitochondrial-focused biohacker stacks (often paired with CoQ10 and Urolithin A). Rucker 2009 PNAS argued PQQ might be a vitamin (deficiency caused growth defects in mice) but FDA has not designated it as essential. Modest human RCT base — most positive trials are small and from Japanese cosmetic ingredient sponsors. Reasonable component of mitochondrial stack at low cost.
Mechanism
Redox-active quinone cofactor; modulates PGC-1α (master regulator of mitochondrial biogenesis), CREB, and SIRT1/3; antioxidant; promotes mitochondrial number and density in cell culture; small fraction of dietary intake from fermented foods, kiwi, parsley, green tea
Dose & route
10-20 mg/day; some products use BioPQQ or MitoQuinone-branded forms
