CoQ10 is an important link in the chain of chemical reactions that produces this energy. It is also a potent antioxidant -- a chemical that "mops up" potentially harmful chemicals generated during normal metabolism. CoQ10 is located in the mitochondria, tiny power plants found in every cell in the body, and effectively supports their energy producing pathways to help fuel the body's daily activity. How CoQ10 Works CoQ10 is a vital component of the energy generating process at the cellular level: it is a true coenzyme. Enzymes, which are biological catalysts, often need assistance in bringing about chemical change within the body. CoQ10 works in the mitochondrial membrane as an electron/proton donor, facilitating the process of energy production. Studies show that oral supplementation with CoQ10 will renew CoQ10 stores in cells and tissues through the mitochondria, where they enhance cellular energy production and sustainability. CoQ10 and Energy Production CoQ10 plays an important role in generating cellular energy and works inside a cell?s mitochondria to provide the supplies necessary for energy production. CoQ10 is an electron/proton carrier that helps the mitochondria to produce adenosine triphosphate (ATP), the body?s energy source. This is vitally important because mitochondria must continually generate ATP to support every cell in the body. CoQ10 is found in high amounts in the cells of the heart, liver, kidneys and pancreas. Oral supplementation with CoQ10 helps maintain CoQ10 stores in these crucial cells and tissues.
