CoQ10 (ubiquinone / ubiquinol) is a vitamin-like substance that is present throughout the body. It is a powerful antioxidant both on its own and in combination with vitamin E, and is vital in powering the body's production of energy.
It is best known for its ability to protect the body, against free radical damage, the root cause of aging. CoQ10 is found throughout the body in cell membranes, especially in the mitochondrial membranes and is particularly abundant in the heart, lungs, liver, kidneys, spleen, pancreas and adrenal glands.
