Description

Product Detail

Overview

PQQ, scientifically known as pyrroloquinoline quinone, is a novel prosthetic group. It exerts effects such as treating heart disease and neurological disorders, protecting the liver, and maintaining mitochondrial function. Pyrroloquinoline quinone is widely present in prokaryotes, plants and mammals. It not only serves as a prosthetic group for numerous enzymes and functions to transfer electrons, protons and chemical groups in enzymatic reactions, but also can stimulate microbial growth, plant pollen germination and promote plant growth.

Efficacy and Functions

Pyrroloquinoline quinone disodium salt supports mitochondrial growth and development and stimulates the rapid proliferation of human cells. In addition, it possesses favorable antioxidant properties, which help scavenge free radicals and reduce cellular damage. Thanks to these two major functions, it delivers potent effects in brain health, cardiovascular health, metabolic health and other aspects.
