A Dutch discovery
PQQ was discovered in the late 1970s as a cofactor of an enzyme in bacteria that break down methanol. Its structure was elucidated in 1979, partly by Hans Duine and his colleagues at Delft University of Technology. The name pyrroloquinoline quinone describes the three rings of the molecule.
Made in the United States
Doctor's Best uses BioPQQ®, which the Japanese manufacturer Mitsubishi Gas Chemical makes through bacterial fermentation. PQQ disodium salt has been authorised in the EU as a novel food since 2018, for adults and up to 20 mg per day.

PQQ, Pyrroloquinoline Quinone by Doctor's Best
Pyrroloquinoline Quinone (PQQ) is a coenzyme, an organic nutrient, which occurs naturally in the human body. PQQ, also known as methoxatin, is a compound related to B vitamins. It is found, among other places, in breast milk, and to a lesser extent in fermented products, spinach, parsley and green tea.
Patented BIOPQQ®
For BIOPQQ®, Doctor's Best uses pure, fully bioactive PQQ. BIOPQQ® is naturally produced through fermentation. This form and dosage are widely used in research with pyrroloquinoline quinone. PQQ is a relatively new supplement, but a very promising one. In the coming years, knowledge about PQQ will continue to increase, as will the various areas of application.
Benefits
PQQ is an endogenous (body's own) substance. BIOPQQ® is produced naturally. Synergistic effect with Q10 ubiquinol, shilajit, R-alpha lipoic acid and acetyl-L-carnitine. Does not contain gluten or soy; GMO-free. Suitable for vegans and vegetarians.
Beneficial bacteria as source of origin
PQQ derives from various types of soil-dwelling bacteria. Vegetable food in particular contains a small amount of PQQ. It can be easily absorbed by the body. Our gut flora may also produce a very small amount of PQQ. Like CoQ10 and ubiquinol, PQQ is a bioactive coenzyme and plays a role inside the mitochondria, the place where energy (ATP) is produced.
