Ubiquinone is the oxidized form of coenzyme Q10 (CoQ10), a fat-soluble compound that helps produce energy in the mitochondria. It is naturally synthesized in the body and is also available through diet and supplementation. Ubiquinone is essential for ATP generation and acts as an antioxidant, though it must be converted to ubiquinol to exert its full protective effects.
While both ubiquinone and ubiquinol play important roles in energy metabolism, ubiquinone tends to be less bioavailable than ubiquinol. Still, it remains widely used in supplements due to its stability and cost-effectiveness.
For individuals engaged in physical activity, ubiquinone can contribute to increased energy production and muscle function, although its effects may be less pronounced than those of ubiquinol in certain populations, especially older adults.
