Pyrroloquinoline Quinone
Unique compound that promotes the growth of new mitochondria, supporting cellular energy and brain health.
What the evidence says
PQQ appears to help in 3 of 3 studies with measurable effects — the evidence leans clearly favourable.
Most evidence is from high-quality randomised trials published 2010–2026 with a typical study size of 34 participants.
Based on 25 studies · 9 RCTs · 453 total participants
Confidence
ModerateWhat the studies found
By outcome
PQQ has an evidence score of 8/10 — strong evidence based on 25 indexed studies. Unique compound that promotes the growth of new mitochondria, supporting cellular energy and brain health.
The commonly studied dose of PQQ is 10-20mg. Research points to an estimated optimal dose around 20mg, with a minimum effective dose near 10mg. Individual response varies — start low and adjust.
The best time to take PQQ is in the morning. Taking it with food is preferred. PQQ (pyrroloquinoline quinone) supports mitochondrial biogenesis through PGC-1α activation and serves as a potent redox cofactor.
Nicotinamide Riboside
Mostly mechanism / observationalA vitamin B3 precursor that efficiently raises cellular NAD+ levels, supporting energy metabolism, mitochondrial function, and healthy aging.
CoQ10
Likely helpsEnhances mitochondrial energy production and acts as a lipid-soluble antioxidant — critical for heart health and depleted by statins.

PQQ is a compound found in soil and certain foods that supports mitochondrial biogenesis — the creation of new mitochondria. This makes it unique among supplements. Research shows benefits for cognitive function, sleep quality, and energy. Often paired with CoQ10 for comprehensive mitochondrial support.

Take with food
| Form | Type |
|---|---|
| 💊BioPQQ capsules (most studied form) | Recommended |
| 💊Generic PQQ disodium salt | Alternative |
BioPQQ is the patented, most studied form. Low doses are effective.
Minimum: 4 weeks
Optimal: 8 weeks
Cycling: Not required
Note: Taking with food may improve absorption. Morning dosing aligns with mitochondrial energy needs.
Based on RCT showing 9-12% TAC increase and isoprostane reduction. Limited to one small study (n=20). Conservative estimates given small sample size and single outcome measure.
Better memory and mental clarity
More sustained energy
Improved sleep quality
Insufficient data; avoid
Generally safe with medications
Tip: Start with lower dose
Tip: Take in morning
PQQ creates new mitochondria; CoQ10 powers them
Comprehensive mitochondrial support
Both support mitochondrial function
Multi-target cellular energy support
PQQ creates new mitochondria; urolithin A removes damaged ones
Complete mitochondrial turnover support
PQQ stimulates mitochondrial biogenesis through CREB and PGC-1α; NR supports the NAD+ substrate for the same pathways — both target mitochondrial quantity and quality.
Synergistic mitochondrial biogenesis and enhanced cellular energy production
PQQ is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are headache, insomnia. Use caution if any of these apply to you: Known allergy or hypersensitivity to PQQ or related compounds.
Citicoline
