Coenzyme Q10 has three different forms, the fully oxidized form known as ubiquinone, the partially oxidized form, ubisemiquinone and the fully reduced form, ubiquinol. In its fully reduced form, CoQ10 acts as a powerful antioxidant.
CoQ10 is involved in a process called aerobic cellular respiration, which is responsible for about 95% of our energy production. This makes Coenzyme Q10 an extremely important molecule for cellular energy, especially in organs with a high energy demand such as the heart, kidneys and liver.
Different from other antioxidants, CoQ10 inhibits both the initiation and propagation of lipid oxidation as well as protein oxidation. Ubiquinol has also been found to reduce pro-inflammatory genes which can cause severe health problems if inflammation persists. 
Typically used for its cardiovascular health benefits, CoQ10 holds many more health benefits due to its link to cellular energy and oxidative damage inhibition.
