CoQ10 is a naturally occurring antioxidant found in the body, essential for the production of adenosine triphosphate (ATP), the energy currency of our cells. It plays a crucial role in the mitochondria, where it aids in the conversion of nutrients into energy. Additionally, CoQ10 has been studied for its potential benefits in heart health, reducing oxidative stress, and improving energy levels, especially in older adults or those with certain health conditions.
