Coenzyme Q10 (CoQ10) is found in every cell in the body (CoQ10 is also called ubiquinone, because it is ubiquitous). CoQ10 is a fat-soluble, vitamin-like substance that plays an important role in energy production. When we are young, our bodies produce all the CoQ10 we need; however, our ability to produce CoQ10 diminishes as we grow older.
At the cellular level, CoQ10 is most concentrated in the energy-producing mitochondria. CoQ10 is required for the production of adenosine triphosphate (ATP), the primary source of cellular energy. ATP is necessary for muscle movement and protein synthesis; it increases energy and stamina, builds muscles, fights fatigue and preserves muscle fibers.
The highest concentrations of CoQ10 are found in the organs with the highest energy requirements, such as the brain, the liver, the kidneys and especially the heart. The heart contains more CoQ10 tan any other organ, which explains why CoQ10 is so frequently associated with heart-health benefits.
In addition to supporting heart health, CoQ10 may be helpful for patients with Parkinson’s disease and may stimulate the immune system, boost endurance, support circulation and fight the effects of aging. CoQ10 is also a potent antioxidant.
