The body contains coenzyme Q10 in every cell. CoQ10 is made by the body, and cells use it to produce energy. Some diseases, such as heart failure, high BP, gum disease, Parkinson disease, blood infections, and HIV infection might lead to a lower level of coenzyme Q10. A vitamin-like substance, coenzyme Q10 is found in the heart, liver, kidneys, and pancreas especially. Meats and seafood contain small amounts of it. Lab-made Coenzyme Q10 is also available. Coenzyme Q10 softgel capsules with antioxidant properties are most commonly used in conditions that affect the heart such as heart failure, high BP, fluid buildup in the body and chest pain. Many other conditions can be treated with this medicine, including migraine headaches, Parkinson's disease, and others. In addition to supporting enzyme activity and protecting the heart and skeletal muscles, coenzymes aid in digestion and other body processes.
