According to Mayo Clinic, some evidence exists supporting the use of coenzyme Q10 for treating heart failure and high blood pressure. CoQ10 appears to have potential use in treating conditions such as eye disease, chest pain from physical exertion, high cholesterol, asthma and the side effects of chemotherapy in children.
According to Mayo Clinic, CoQ10 does not appear to be helpful in treating diabetes, hepatitis C and Huntington's disease. CoQ10 is an antioxidant naturally produced by the body, required for basic cell function. CoQ10 levels get lower as people get older, and the antioxidant's levels also may be low due to various conditions, such as diabetes, cancer, heart conditions, HIV and AIDS, Parkinson's disease and muscular dystrophy. CoQ10 supplements can be helpful for boosting the antioxidant's level in the body when needed.
