The body makes coenzyme Q10 naturally, and it is an antioxidant that helps with basic functions of the cells, explains Mayo Clinic. As people age, the amount of coenzyme Q10 in the body decreases. Additionally, people who have diabetes, cancer, certain genetic disorders, Parkinson's disease or muscular dystrophies may have low levels of coenzyme Q10. There are also medications that lower the amount of coenzyme Q10 in the body.

People who require more coenzyme Q10 can take supplements, states Mayo Clinic. There is some scientific evidence that taking coenzyme Q10 can help treat heart failure and high blood pressure. As of 2015, there is also evidence that using coenzyme Q10 may prove promising to treat eye disease, chronic fatigue, asthma and high cholesterol. Children who require chemotherapy may also find relief from the side effects of treatment by taking coenzyme Q10.

People may also choose to take coenzyme Q10 to improve exercise performance or to treat heart muscle problems, but the evidence is conflicting, claims Mayo Clinic. Additionally, there is contrary evidence that coenzyme Q10 works for managing hepatitis C, diabetes and Huntington's disease.
