CoQ10 is a nutrient produced naturally within the mitochondrial membrane and plays a critical role in the electron transport chain. CoQ10 Active is designed to support cellular energy and mitochondrial function through a combination of CoQ10 and pyrroloquinoline quinone (PQQ).* PQQ supports the function of mitochondria, the powerhouses of the cell.* As a result, this nutrient also provides support for parts of the body that need large amounts of energy for optimal function, such as the brain and nervous system.
