Coenzyme Q10 (CoQ10) is similar to a vitamin. It is found in every cell of the body, where it is used it to produce energy for cell growth and maintenance. Coenzyme Q10 is also responsible for harvesting over 75% of the ATP energy from food.
Coenzyme Q10 also acts as an antioxidant, which protects the body from damage caused by harmful molecules. It also help enzymes work to digest food and perform other body processes, and they help protect the heart and skeletal muscles. It is also believed to boost energy and speed recovery from exercise.
Coenzyme Q10 can become depleted during periods of excessive energy demands. Levels of it are also significantly lower in women who use oral contraceptives, which may in turn increase the risk of cardiovascular disease. In addition, most cholesterol-lowering drugs deplete coenzyme Q10.
