Product Description
PQQ (Pyrroloquinoline Quinone), also known as Methoxatin, is a rare and high-activity natural bioactive coenzyme existing in microorganisms, plants and human tissues. As a vital redox cofactor, PQQ is famous for its unique mitochondrial biogenesis function, which is different from conventional antioxidants. Our PQQ powder adopts advanced microbial fermentation combined with preparative HPLC fine purification technology, reaching 99% ultra-high purity, with stable molecular structure, ultra-low impurity content and durable biological activity, fully meeting high-end health product production and biomedical research standards.
Different from common plant extracts and ordinary antioxidant ingredients, high-purity PQQ is a single active coenzyme monomer with precise chemical structure and targeted biological efficacy. The whole production process adopts sterile fermentation and low-temperature freeze-drying technology, which completely retains the active structure of PQQ, removes fermentation residues, heterologous proteins and harmful impurities, and solves the problems of unstable activity and low purity of traditional crude PQQ products. All production procedures comply with GMP dust-free purification standards, ensuring excellent batch-to-batch consistency and experimental repeatability.
PQQ possesses outstanding mitochondrial activation and regeneration capabilities. It can effectively stimulate the proliferation and repair of intracellular mitochondria, improve cellular energy metabolism efficiency, relieve chronic fatigue caused by insufficient energy supply, and enhance body vitality. As a super antioxidant, PQQ’s free radical scavenging ability is far superior to conventional antioxidants such as vitamin C and E. It can deeply remove intracellular reactive oxygen species, inhibit lipid peroxidation, reduce cellular oxidative damage, and delay whole-body and skin aging.
In neuroprotection and brain health regulation, PQQ protects nerve cells from oxidative and inflammatory damage, promotes nerve cell repair and growth, improves cerebral microcirculation, enhances memory and concentration, and effectively relieves brain fatigue and cognitive decline caused by aging and long-term high-intensity work. It also exerts significant anti-inflammatory and immune-balancing effects, inhibiting chronic low-grade inflammation in the body and maintaining systemic immune homeostasis.
In skincare and anti-aging fields, PQQ resists cellular photoaging and oxidative aging, repairs damaged skin energy circulation, improves dull skin, fine lines and sagging problems caused by energy decline, and revitalizes skin vitality. With mild properties and high safety, it is compatible with various oral health formulas and external skincare formulas, becoming a core raw material for high-end anti-aging and energy health products.
Our premium PQQ presents uniform orange-red crystalline fine powder with delicate texture, no caking and no peculiar smell. Every batch undergoes full-index quality inspection including HPLC purity calibration, NMR structural identification, mass spectrometry molecular verification and cell-level activity testing. Strict quality control complies with international food-grade and cosmetic-grade raw material standards. With stable physical and chemical properties and wide formula compatibility, it is widely used in brain health supplements, anti-aging products, energy metabolism formulas and biomedical pharmacological research.
We maintain long-term stable bulk inventory, support flexible supply from small trial samples to large-scale industrial orders, and provide customized packaging solutions to meet diversified R&D and mass production needs of global customers.
