PQQ: A New-Generation Nutritional Ingredient with Outstanding Potential

As public interest in nutrition at the cellular level grows, pyrroloquinoline quinone (PQQ), a vitamin-like active ingredient, is attracting rising attention in the field of dietary nutrition. Unlike conventional antioxidants, PQQ features redox cycling capacity and cellular signal modulation, endowing it with versatile potential for nutritional applications.

PQQ is a water-soluble quinone active substance that the human body can barely synthesize on its own; it is mainly obtained exogenously through diet. It possesses a distinctive antioxidant mechanism and is capable of repeated redox cycles. Its free radical scavenging efficiency at the molar level surpasses that of many common polyphenol antioxidants. Reduced PQQ can also assist in the regeneration of vitamin E, jointly helping the body counter oxidative stress and maintain cellular homeostasis.

Mitochondria are known as the powerhouses of cells, and mitochondrial health is closely linked to daily energy metabolism in the human body. Scientific research indicates that PQQ helps elevate intracellular NAD⁺ levels, thereby regulating sirtuin-related signaling pathways and upregulating key regulatory factors such as PGC‑1α and TFAM. It facilitates mitochondrial biogenesis, supports cellular energy metabolism, and lays a nutritional foundation for daily bodily vitality.

Beyond cellular energy metabolism, PQQ also offers nutritional support for multiple aspects of physical condition. Relevant human and animal studies have observed that appropriate PQQ intake helps sustain normal immune-related parameters in the body. It also modulates the intestinal barrier and gut microbiota composition to support intestinal microecological balance. Furthermore, trials suggest that PQQ supplementation shows a promising trend of positive nutritional support for cognitive status.

In terms of safety, disodium PQQ has obtained GRAS (Generally Recognized As Safe) status from the US FDA. Available toxicological studies demonstrate that PQQ exhibits good safety for consumption within the typical dosage range for dietary supplements, making it suitable for the development of dietary nutritional products.

It should be noted that PQQ is a dietary nutritional raw material. Health food is not medicine and cannot replace pharmaceuticals for disease treatment. Relevant health benefits are still under ongoing research, and product development must comply with regulatory requirements of respective countries. Based on current scientific evidence, with multiple nutritional properties including mitochondrial support, antioxidant effects and gut regulation, PQQ represents a health ingredient with broad development prospects.
