Product Introduction

What is Pyrroloquinoline Quinone Powder

Pyrroloquinoline Quinone (PQQ) Powder is produced by Gram-negative bacteria, it has a wide range of nutritional effects on microorganisms, animals and plants, and has antioxidant nutrients. 

PQQ Origin

PQQ in nature is currently believed to only originate from the synthesis of Gram-negative bacteria (G-). Through the material cycle in nature, it affects animals, plants and other microorganisms other than G-.

PQQ Content in Foods

Although PQQ is synthesized from G-, some food materials also contain small amounts of PQQ due to the material and energy exchange between microorganisms and animals and plants in the ecosystem.

In recent years, when Kumazawa et al. analyzed various daily foods including vegetables, fruits and beverages, they also found that fruits and vegetables all contained varying amounts of PQQ.

Among them, fermented soybeans (natto) have the highest PQQ content (61ng/g), and rice wine has the lowest (3.65ng/ml).

The content of parsley and green peppers in vegetables, kiwi and papaya in fruits, green tea and oolong tea in drinks, and tofu that people often eat are all about 30ng/g.

American researchers tested and found that the PQQ content in human milk was as high as 140~180ng/ml. In addition, PQQ has also been detected in foods such as eggs and skimmed milk.

Pyrroloquinoline Quinone Powder Benefits

Super Antioxidant Capacity

Pyrroloquinoline quinone disodium salt is a new redox cofactor different from nicotinamide nucleotides and flavin nucleotides. It can catalyze redox reactions and promote the production and development of animals and plants.

Antioxidant power far exceeds vitamin C and vitamin E.


Pqq can effectively prevent tumor cells from replicating and causing them to undergo apoptosis. It can also scavenge free radicals and prevent tumors.

It can have a very good anti-cancer effect.

Improve Body Immunity

Pyrroloquinoline Quinone (PQQ) Powder can stimulate the growth of human cells, especially T cells and B cells and cause these cells to produce antibodies and improve the body's immunity.

Regulate Liver Damage

Reduce serum bilirubin and alaninase levels, maintain normal liver function, and prevent liver disease.

Good for Brain

Pqq can effectively repair nerve fibers and activate neurons, thereby activating dormant nerve cells, effectively improving memory and preventing Alzheimer's disease.

PQQ for Skin

pqq can replenish collagen, reduce the damage of free radicals to the body, promote the body's absorption of amino acids, effectively improve skin condition, and has the effect of removing wrinkles and skin whitening.

Product Uses

Pyrroloquinoline Quinone (PQQ) is utilized for its extensive range of health benefits and is involved in various therapeutic applications:

Mitochondrial Support: Enhances mitochondrial growth and function, crucial for energy generation.

Neuroprotective Effects: Promotes the growth of nerve growth factors and supports overall brain health.

Antioxidant Activity: Highly effective in scavenging free radicals, thus protecting cells from oxidative damage.

Supports Cardiac Health: Helps reduce the size of damaged areas in acute heart attacks and is a potential therapeutic agent against cardiac dysfunction.

Metabolic Benefits: Influences pathways related to energy metabolism and may assist in weight management and diabetes control.

PQQ Safety and Dosage

The United States approved the first PQQ dietary supplement in 2009.

Since PQQ is slightly soluble in water, the supplement ingredient is PQQ sodium salt (PQQ-2Na+), which has better solubility;

in 2018, the European Union also approved PQQ-2Na+ as healthy food, suitable for adults except pregnant women and lactating women.

Recommended consumption is ≤20 mg/day.
