I.What is Pyrroloquinoline Quinone Disodium Salt?
Pyrroloquinoline Quinone Disodium Salt is a naturally occurring bioactive substance, hailed by scientists as a "super vitamin." It is widely distributed in fresh fruits and vegetables such as kiwifruit, papaya, and spinach, as well as fermented foods like natto. It can also be synthesized by certain microorganisms. As a non-vitamin coenzyme, PQQ-Na2 participates in various metabolic processes in organisms, and its unique physiological activity has attracted continuous attention from the global scientific research community.
II.Mechanism of Action
PQQ-Na2 first participates in the catalytic reaction of dehydrogenase in the body, accelerating the oxidative decomposition of carbohydrates and fats to supply basic cellular energy; its core function lies in specifically activating the PGC-1α signaling pathway that regulates mitochondrial biogenesis, enabling the repair of damaged mitochondria and the generation of new mitochondria, thereby enhancing cellular energy supply at the source. Meanwhile, relying on its own redox properties, it can efficiently scavenge excess free radicals, reduce oxidative stress damage to cells, and synergize with other antioxidants to enhance the body's overall antioxidant capacity.
III.The Core Benefits
1.Mitochondrial Activation and Regeneration: This is PQQ-Na2's most core benefit. As the "energy factory" of human cells, the decline in mitochondrial function directly leads to issues such as fatigue and aging. PQQ-Na2 not only activates the existing mitochondria, improving the efficiency of cellular energy supply, but also promotes the generation of new mitochondria, thereby delaying the aging at the source.
2.Antioxidant and Free Radical Scavenging: PQQ-Na2's antioxidant capacity is far superior to that of traditional antioxidants such as vitamins C and E. It can efficiently scavenge excess free radicals in the body and reduce oxidative stress damage to cells. It protects the integrity of cell membranes, lowers the risk of skin aging and organ function decline.
3. Cognitive Function Protection and Enhancement: PQQ-Na2 can cross the blood-brain barrier and provide effective protection for brain nerve cells. It promotes the synthesis of neurotrophic factors (such as BDNF), aiding in the repair and regeneration of nerve cells, thereby improving memory and concentration, delaying the decline in cognitive function in middle-aged and elderly groups.
4. Blood Sugar Regulation and Metabolism Improvement: PQQ-Na2 can promote the absorption and utilization of glucose by activating key signaling pathways in the body, helping to stabilize blood sugar levels. It has an auxiliary regulating effect on people with prediabetes and metabolic syndrome. At the same time, it promotes fat metabolism, and assists in weight management.
IV.Safety
As a relatively safe supplement, PQQ-Na2 meets all the requirements of the U.S. Food and Drug Administration (FDA) for "Generally Recognized as Safe" (GRAS) and has successively passed safety certifications in Canada, Japan, and the European Union. In 2022, it was certified as a novel food ingredient by the National Health Commission of the People's Republic of China. The recommended daily intake of PQQ-Na2 by the National Health Commission is <20 mg/day, the maximum usage level in beverages is 40 mg/kg, and for solid beverages, it is calculated based on the liquid mass after reconstitution.
