Pyrroloquinoline quinone (PQQ) is an emerging mitochondrial nutrient gaining attention in nutritional science for its potential role in supporting cellular energy production, cognitive performance, and healthy aging. Research suggests that PQQ may stimulate mitochondrial biogenesis—the process by which cells create new mitochondria—while also acting as a powerful antioxidant that protects cells from oxidative stress. Found naturally in foods like fermented soybeans, green tea, and kiwi fruit, PQQ is often paired with synergistic nutrients such as CoQ10, alpha-lipoic acid, and acetyl-L-carnitine to support metabolic health, brain function, and physical performance. In this Ingredient Science deep dive from Nutra Quality Labs’ Precision Nutrition Insights blog, we explore the mechanisms, clinical research, dietary sources, and synergistic ingredients that make PQQ one of the most promising compounds in the growing field of mitochondrial health and cellular optimization.
