Coenzyme Q10 is perhaps one of the lesser known substances needed for the maintenance of one's overall health. It is considered as vitamin-like, but unlike the vitamins, it is naturally synthesized in the body. It was discovered in 1957 by Fred Crane in the mitochondria of a beef liver, although its molecular structure was identified in 1958. Moreover, various studies on the substance have been conducted, and as a whole, it has been found to be an essential substance for the maintenance of one's overall health. Without the substance, the energy that the cells and the systems in the body use to carry out their function will not be produced.

The mitochondria are known as the powerhouses of cells because they create energy for the cells. And, for the mitochondria to create this energy, they need sufficient amounts of Coenzyme Q10. The substance may be naturally synthesized in the body, but its levels tend to decline as a person grows older. By the time they reach thirty, they may start to experience this decline of the levels of the substance. Another factor that may lead to deficiency of the substance is the intake of statins, which are drugs used to lower cholesterol levels. The most common effect of not having sufficient levels of the substance is overall weakness. However, this may lead to more serious health problems such as angina, arrhythmia, high blood pressure, and heart failure.

Because of the importance of Coenzyme Q10 on overall health, it has been made available as a dietary supplement. Studies have found its positive effect on those taking chemotherapy drugs, highly stressed individuals, and athletes aiming to improve their energy levels, among others. Aside from supplementation, one may get the substance from certain kinds of food such as fish, meat, sesame, soybean, and vegetable oils.
