Mechanism of Action

PQQ

PQQ activates PGC-1alpha (peroxisome proliferator-activated receptor gamma coactivator 1-alpha), the master transcriptional regulator of mitochondrial biogenesis. PGC-1alpha coactivates NRF-1 and NRF-2, which drive expression of mitochondrial transcription factor A (TFAM) and nuclear-encoded mitochondrial genes—the process of creating new mitochondria in existing cells. This is unique among commercially available supplements. PQQ also provides antioxidant protection through extremely efficient redox cycling at the N5 position; it can undergo thousands of oxidation-reduction cycles before being exhausted, estimated at 5,000x the efficiency of vitamin C. PQQ activates the CREB (cAMP response element-binding protein) signaling pathway and may enhance NGF signaling, supporting BDNF expression, synaptic plasticity, and neuronal survival.
