Coenzyme Q-10 (CoQ-10) is a vitamin-like substance found throughout the body, but especially in the heart, liver, kidney, and pancreas. It is eaten in small amounts in meats and seafood. Coenzyme Q-10 can also be made in a laboratory. It is used as medicine.
Many people use coenzyme Q-10 for treating heart and blood vessel conditions such as congestive heart failure (CHF), chest pain (angina), high blood pressure, and heart problems linked to certain cancer drugs. It is also used for diabetes, gum disease (both taken by mouth and applied directly to the gums), breast cancer, Huntington’s disease, Parkinson’s disease, muscular dystrophy, increasing exercise tolerance, chronic fatigue syndrome (CFS), and Lyme disease. Some people think coenzyme Q-10 will treat hair loss related to taking warfarin (Coumadin), a medication used to slow blood clotting.
