PQQ activates the CREB → PGC-1α signaling pathway, which is the master switch for mitochondrial biogenesis — literally telling cells to build new mitochondria. More mitochondria = more cellular energy capacity. As an antioxidant, PQQ is remarkably stable — it can undergo ~20,000 redox cycles compared to ~4 for vitamin C, making it one of the most efficient catalytic antioxidants known. It also acts as a growth factor for nerve cells (NGF induction), though this is primarily demonstrated in cell culture and animal models.
No significant drug interactions have been identified in clinical literature. PQQ is a naturally occurring compound found in nanogram quantities in many foods. At supplement doses of 10-20mg, no pharmacological interactions have been documented.
