Pyrroloquinoline Quinone Disodium Salt
Brief Introduction:
The main component of pyrroloquinoline quinone disodium salt is pyrroloquinoline quinone, referred to as PQQ, which is a new prosthetic group with similar physiological functions to vitamins and widely exists in prokaryotes, plants and mammals, such as Fermented soybeans or natto, green peppers, kiwi fruit, parsley, tea leaves, papaya, spinach, celery, breast milk, etc.
The biological functions of PQQ are mainly concentrated in two aspects. First, it can support the growth and development of mitochondria and stimulate the rapid growth of human cells; second, it has good antioxidant properties, which can help scavenge free radicals and reduce cell damage. These two functions make it powerful in brain health, cardiovascular health, and metabolic health. Because the body cannot synthesize PQQ on its own, it can be supplemented through dietary supplements, usually in powder form, prepared by microbial fermentation.
