Coenzyme Q10 (CoQ10 or quinone) is produced by the body and is necessary for the basic functions of the cell. Approximately 95% of the body's energy is converted with the assistance of CoQ10.
Because CoQ10 is an antioxidant, most people associate it with the ability scavenge free radicals and prevent heart disease. However, CoQ10 has a greater role in the body than this. This is an enzyme that is located in all of the mitochondria in every cell of the body. Because the heart is such a large and important muscle, a large quantity of CoQ10 is located here.
As an essential component of mitochondria in the cell, Coenzyme Q10 plays a vital role in producing energy in the cell. It is involved in manufacturing ATP, which is the energy that the entire body depends on. Just as you car cannot function without gas, the body cannot function without CoQ10.
