What Is CoQ10?

Coenzyme Q10 is a powerful, naturally occurring antioxidant found in every cell of the body, especially within the mitochondria—the energy-producing structures of our cells. This essential molecule is crucial in cellular energy production. It is concentrated in organs with high energy needs, like the heart, liver, and kidneys, where it supports optimal cellular health by enhancing ATP production and reducing mitochondrial abnormalities.


CoQ10 is essential to the mitochondrial electron transport chain, a complex series of reactions that produce ATP, the energy currency of the body. By facilitating electron flow within this chain, CoQ10 drives the production of ATP, which fuels nearly every biological process, from muscle contraction to cell repair. Without adequate CoQ10 levels, mitochondrial function can decline, potentially leading to increased oxidative stress and energy shortages within cells, along with symptoms such as fatigue, muscle pain, and cognitive decline.
