CoQ10 (Coenzyme Q10) — Uses, Dosage, Side Effects & Safety

Drug class: Nutritional supplement

Overview

CoQ10 (Coenzyme Q10) is a naturally occurring antioxidant found in every cell of the body. It plays a crucial role in producing energy within cells, especially in organs with high energy needs like the heart, muscles, and kidneys. CoQ10 is commonly used as a dietary supplement to support heart health, improve energy levels, and as an adjunct in certain medical conditions such as heart failure, migraine prevention, and statin-induced muscle symptoms. CoQ10 works by helping mitochondria (the cell's energy factories) generate adenosine triphosphate (ATP), the main energy currency of the cell. It also protects cells from oxidative damage. Patients should know that while CoQ10 is generally well tolerated, it may interact with some medications and is not a substitute for prescribed treatments. Always consult your healthcare provider before starting CoQ10.
