PQQ (Pyrroloquinoline Quinone)
A redox cofactor and potent antioxidant that uniquely stimulates mitochondrial biogenesis - the growth of new mitochondria. Works synergistically with NMN to comprehensively support cellular energy production. Where NMN improves existing mitochondria, PQQ creates new ones.

Mechanism of Action
PQQ (Pyrroloquinoline Quinone) is unique among available supplements for its ability to stimulate mitochondrial biogenesis -- the creation of entirely new mitochondria within cells.
Key mechanisms:
- PGC-1alpha activation -- PQQ activates the master regulator of mitochondrial biogenesis, driving the creation of new mitochondria rather than merely improving existing ones
- CREB pathway modulation -- activates the cAMP response element-binding protein, influencing gene expression for energy metabolism
- Redox cycling -- PQQ can cycle between oxidised and reduced forms thousands of times, making it an exceptionally efficient antioxidant catalyst
- Neuroprotection -- protects neurons from oxidative damage with particular relevance to age-related neurodegenerative processes
Why PQQ + NMN Is the Complete Mitochondrial Stack
| | NMN | PQQ | |---|---|---| | Primary target | NAD+ restoration | Mitochondrial biogenesis | | Effect | Improves existing mitochondria | Creates new mitochondria | | Pathway | NAD+/SIRT1 | PGC-1alpha/CREB |
Taking both addresses both the quality (NMN) and quantity (PQQ) of mitochondria simultaneously.

The Advanced Mitochondrial Stack. Take PQQ morning alongside NMN.
Resveratrol activates SIRT1 which feeds into PGC-1alpha - the same pathway PQQ stimulates. Additive effect on mitochondrial biogenesis.
