SupplementLast updated
AVELOR SUMMARY
PQQ is a redox cofactor that stimulates mitochondrial biogenesis, the creation of new mitochondria.
Our research identifies this as the primary mechanism behind PQQ's biological activity, though the clinical evidence in humans is surprisingly thin.
A small Japanese trial found 20mg/day improved sleep quality and reduced fatigue, and another found it reduced CRP (inflammation) by 45%.
PQQ is genuinely active at the molecular level (PGC-1α activation, antioxidant cycling), but the human evidence doesn't yet match the mechanistic promise.
It's expensive, and better-studied options exist for most claimed benefits.
WHAT IT DOES
PQQ activates the CREB → PGC-1α signaling pathway, which is the master switch for mitochondrial biogenesis, literally telling cells to build new mitochondria. More mitochondria = more cellular energy capacity. As an antioxidant, PQQ is remarkably stable, it can undergo ~20,000 redox cycles compared to ~4 for vitamin C, making it one of the most efficient catalytic antioxidants known. It also acts as a growth factor for nerve cells (NGF induction), though this is primarily demonstrated in cell culture and animal models.
OPTIMAL DOSAGE
Look for: BioPQQ brand (Mitsubishi Gas Chemical, most clinical data); 10-20mg per capsule; disodium salt form
Avoid: Products with <10mg PQQ; unbranded PQQ with unknown synthesis quality; combination products hiding PQQ in proprietary blends
Minimum effective dose: 10mg/day
Third-party tested brands: Life Extension (BioPQQ), Doctor's Best (BioPQQ), Jarrow Formulas
No significant drug interactions have been identified in clinical literature. PQQ is a naturally occurring compound found in nanogram quantities in many foods. At supplement doses of 10-20mg, no pharmacological interactions have been documented.
