PQQ

Pyrroloquinoline Quinone (PQQ) is a novel redox coenzyme belonging to the tricyclic aromatic quinone compound class, with physiological functions similar to vitamins. Its chemical formula (disodium salt) is C₁₄H₄N₂Na₂O₈, with a molecular weight of 374.17 and CAS number 122628-50-6. PQQ is referred to as the "fourteenth vitamin" by the global medical community and is considered an essential nutrient for the human body.

PQQ is widely distributed in plants, animals, and human tissues, and is particularly abundant in breast milk, serving as an essential factor for infant healthy development. The human body cannot synthesize PQQ endogenously and must obtain it through dietary sources. PQQ possesses powerful antioxidant, anti-inflammatory, and mitochondrial metabolism-regulating properties. PQQ has been featured multiple times in the prestigious journals Nature and Science for its potent anti-aging and cellular rejuvenation effects.
