The main food sources of coenyzme Q10 are beef and chicken, according to Everyday Health. Dietary sources are limited, so coenzyme Q10 is available in a variety of supplement forms, including tablets, oral spray and soft gel capsules. Adults take between 30 and 200 milligrams each day.
Coenzyme Q10 occurs naturally in the cells of the human body and is primarily responsible for creation of adenosine triphosphate, notes Everyday Health. Adenosine triphosphate, or ATP, helps direct energy within human cells and throughout the body and plays a key role in metabolism and muscle function. As of 2015, the benefits of coenzyme Q10 are still under investigation, but the supplement may help treat heart disease, high blood pressure, high cholesterol, gum disease and diabetes.
