Coenzyme Q10, often abbreviated as CoQ10, is a naturally occurring antioxidant found in the cells of the body. It plays a crucial role in the production of energy within the mitochondria, which are the powerhouses of cells. CoQ10 is essential for maintaining healthy cellular function and is involved in various metabolic processes. As we age, the levels of CoQ10 in the body can decrease, potentially leading to reduced energy levels and increased oxidative stress. CoQ10 is available as a dietary supplement and is often used to support heart health and improve energy levels. It can also be found in small amounts in foods like meat, fish, and whole grains.
