Overview
A synthetic phenothiazine dye and the world's oldest synthetic drug (1876). Acts as an alternative electron carrier in the mitochondrial electron transport chain, bypassing Complex I and III dysfunction. At nanomolar doses, it enhances mitochondrial respiration, ATP production, and demonstrates remarkable neuroprotective effects in neurodegenerative disease models.
Summary
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.
