Pyrroloquinoline Quinone (PQQ)

Pyrroloquinoline quinone (henceforth PQQ powder) is a small quinone molecule that has the ability to be a REDOX agent, capable of reducing oxidants (an antioxidant effect) and then being recycled by glutathione back into an active form. It appears to be quite stable as it can undergo several thousand cycles before being used up, and it is novel since it associates with protein structures inside the cell (some antioxidants, mostly notably carotenoids like β-carotene and Astaxanthin, are located at specific areas of a cell where they exert proportionally more antioxidant effects due to proximity; PQQ seems to do these near proteins like carotenoids do so at the cell membrane).

PQQ powder is present in nanomolar quantities in most foods and in most animal tissue. It promotes growth, mitochondrial function, and development in vivo and stimulates cell proliferation and viability in culture. It is a potent antioxidant that scavenges superoxide and peroxynitrite. It is a neuroprotectant against 6-hydroxydopamine-induced and hypoxia/ischemia-induced neurotoxicity. PQQ conjugates to α-synuclein in vitro, inhibiting the formation of amyloid fibrils.

1. Improve the body’s immune function

As a necessary factor of human development, it can stimulate the growth of cells in the body, especially the activation of human B cells, and T cells, antibody production, and improve the immune function of the human body.PQQ is the most powerful bioactive substance so far.

2. Prevent and treat the liver damage

Can significantly reduce serum bilirubin, and alanine aminotransferase levels, make liver function normal, regulate liver damage and have a very good curative effect on liver disease.

3. Reduce free radical damage to the human body

PQQ is a kind of oxidoreductase prosthetic group, involved in biological REDOX reactions in the body, can effectively remove free radicals in the body, reduce the harm to human body free radicals, protect tissues, reduce the body damage caused by various diseases, such as heart disease, cancer and all kinds of inflammation. Free radicals are the source of diseases.

4. Regulate various neurological diseases

PQQ is a new kind of water-soluble vitamin, that can promote the synthesis of neural factors in the human body, and regulate various neurological diseases.

5. Promote the absorption of amino acids

PQQ is the prosthetic group of quinone protease, which participates in the respiratory electron transport chain, in the human body through the effect of glucose, and can promote the absorption of amino acids. Amino acid composition of cell SAP and synthetic protein peptide is the main raw material and is an important part of the body’s biological active substances.

6. Prevent and treat Alzheimer’s disease

PQQ has special biological activity and physiological function but also has a repair of nerve fibers, the activation of neurons, activate the dormancy of the nerve cells, can effective prevention and treatment of Alzheimer’s disease and improved memory. Can effectively improve intelligence.

7. Promote the synthesis of glutathione

Glutathione by glutamic acid, cysteine and glycine combination of three peptides, has an important antioxidant effect, integrating detoxification, harmful to the body poison into a harmless substance, excreted in vitro, glutathione is a bioactive enhancer.PQQ can promote the body’s glutathione synthesis, prevent and the accumulation of hepatic bilirubin in cataracts.

8. Strong anticancer function

It can make the NK cells and other immune cells gathered themselves together, and play a corps of operational capability, more effectively killing tumor cells.
