Natural Antioxidant and Anti-Inflammatory Factor: PQQ

In modern life, oxidative stress and chronic low-grade inflammation are core drivers of obesity, metabolic diseases, and aging-related issues. Pyrroloquinoline quinone (PQQ), a bioactive substance naturally found in fermented soybeans, fruits, and vegetables, possesses potent dual antioxidant and anti-inflammatory properties, making it an important nutritional factor for maintaining cellular homeostasis and improving metabolic health.

Core Advantage in Cell Protection

PQQ’s antioxidant capacity far exceeds that of ordinary antioxidants, representing its core advantage in cell protection. As a redox-active aromatic tricyclic ortho-quinone, PQQ efficiently scavenges harmful aryloxy and peroxy radicals in the body, with antioxidant efficiency 100–1000 times higher than other quinone substances. More importantly, PQQ exhibits excellent stability, resisting self-oxidation or polymerization-induced inactivation, enabling sustained functionality. Through reversible redox reactions, it neutralizes reactive oxygen species (ROS) generated by oxidative stress, reduces free radical damage to cell membranes and mitochondrial DNA, and blocks oxidative stress-induced cellular damage at its source.

Precision Inhibition of Inflammatory Responses

At the anti-inflammatory level, PQQ precisely suppresses chronic inflammatory responses through multi-pathway regulation. Metabolic issues such as obesity induce sustained release of pro-inflammatory factors including IL-6, TNF-α, and IL-1β, creating a low-grade inflammatory state. PQQ directly inhibits key inflammatory pathways such as NF-κB, MAPK, and JAK, blocking pro-inflammatory gene transcription and reducing inflammatory factor release. Simultaneously, it activates the Keap1/Nrf2 antioxidant pathway, enhancing the cell’s intrinsic antioxidant defense capacity and indirectly alleviating inflammatory responses, thereby preventing sustained tissue and organ damage from inflammation.

Furthermore, PQQ’s antioxidant and anti-inflammatory effects are closely synergized with mitochondrial protection. It upregulates the key mitochondrial regulatory factor PGC-1α, promoting mitochondrial biogenesis, enhancing mitochondrial function, and reducing ROS generation—forming a virtuous cycle of “antioxidation–mitochondrial protection–inflammation suppression.” This is particularly effective in improving mitochondrial dysfunction and inflammatory disorders associated with obesity.

As a safe dietary supplement approved by the European Union, a daily PQQ supplementation dose of 20 mg is safe and reliable. With its highly efficient antioxidant capacity, multi-pathway anti-inflammatory mechanisms, and mitochondrial protective effects, PQQ provides a natural and safe new option for combating oxidative stress and alleviating chronic inflammation, offering broad application prospects in the field of metabolic health maintenance.
