Overview
Cofactor stimulating mitochondrial biogenesis (PGC-1α).
- Trace in fermented foods, kiwi
- PQQ disodium salt
Mechanism of action
Upregulates PGC-1α, NRF1/2, and TFAM — mitochondrial biogenesis transcription factors.
- · Mitochondrial biogenesis
Effects on the body
Organ system effects
PQQ supports mitochondrial ATP production and fatigue resistance.
PQQ acts on hallmarks of aging including oxidative stress, mitochondrial dysfunction, and senescence signaling.
