CoQ10 is recognized for its significant role in the electron transport chain as well as being one of the body's most vital antioxidants. It is found in the mitochondria, the energy-producing center or "powerhouse" of the cell. In addition to being produced in the body, CoQ10 can also be obtained in small amounts through certain dietary sources, such as fish and organ meats; yet these amounts may often be inadequate to meet the body's demands. Additionally, age and various illnesses, as well as the use of various medical classes, increase the need for CoQ10. Thus, supplemental amounts may be beneficial for supporting health and helping to prevent or limit oxidative damage.
