PQQ Lozenge by Seeking Health provides 20 mg of BioPQQ® in each easy-to-deliver lozenge. PQQ is a small quinone molecule that may help support cellular energy production as well as the body’s defenses against oxidative damage. Sometimes called “the other CoQ10,” PQQ can be used over and over again in redox reactions by conversion back into its active form. Because of its impressive potential for recycling, it is considered quite stable in comparison to CoQ10 and other antioxidants. PQQ is present in many forms around us. It is thought to be a component in interstellar dust. It has also been identified as an enzyme cofactor in certain bacteria, and as an important constituent in most plants. Recently, the potential roles of PQQ in humans have been subjects of keen scientific interest. Ongoing research is being conducted to explore the potential roles and benefits of PQQ in human health and wellness, including its potential importance in metabolism, mitochondrial function, and cognitive health.
