CoQ10 (also known as ubiquinone) is an antioxidant synthesised in the body. It is a vital part of energy production systems in the mitochondria, the power houses of the cells, and it can become depleted as we get older. The heart muscle uses significant quantities of CoQ10, as it is permanently active. Suitable levels of CoQ10 are even more necessary for those taking statin medication, as these drugs can inhibit the body’s synthesis of coenzyme Q10.
