PQQ activates PGC-1alpha via CREB phosphorylation, directly stimulating mitochondrial biogenesis — the formation of new mitochondria. It acts as a redox cycling agent capable of thousands of catalytic oxidation-reduction cycles (compared to ~4 for vitamin C), providing exceptional antioxidant capacity. PQQ also modulates NMDA receptor signaling and promotes nerve growth factor (NGF) synthesis, supporting neuronal health and cognitive function.
