PQQ
Description
Pyrroloquinoline quinone (PQQ) is a novel redox cofactor found in small amounts in plant foods that activates CREB and PGC-1alpha, transcription factors that stimulate the growth of new mitochondria in a process known as mitochondrial biogenesis. This makes PQQ unique among supplements in its ability to actually increase the number of mitochondria in cells, not just support their function. It also functions as a potent antioxidant capable of cycling thousands of times without becoming depleted. Research supports benefits for memory, cognitive function, inflammation reduction, and energy levels, particularly when combined with CoQ10.
Effects
First 2 weeks
subtle
Weeks 4–8
Ongoing
How It Feels
Gentle and gradual; some people notice steadier energy and clearer thinking over a month, others little. It works on mitochondrial density, which is inherently a slow process. Commonly stacked with CoQ10.
Evidence
Evidence Strength
Preliminary (limited / small human data)
Caveats
Mitochondrial biogenesis claims are based substantially on animal data; human trials are few and small.
Usage
Commonly Referenced Starting Amount
10 mg/day
Commonly Referenced Amount
10–20 mg/day covers what's been used in the small existing human trials
Referenced Upper Limit
No upper limit has been established; human evidence here is still preliminary
Onset
4–8 weeks (mitochondrial)
Biomarkers to Track
Subjective
(Daily)
Energy and mental clarity (1–10)
Exercise endurance score
Sleep quality score
Objective
(Quarterly)
Plasma PQQ level (specialty)
HRV baseline score
NGF levels (specialty test)
Generally safe in studied doses.
Pregnant and breastfeeding women, due to limited data.
Expecting fast results, when mitochondrial changes are slow.
