Mitochondria produce the energy necessary for the cell functioning through a process called “cellular respiration” which requires oxygen and produces energy. During cellular respiration, some toxic forms of oxygen (called oxygen free radicals) can be produced. These free radicals must be neutralized by other substances to avoid cellular damage.(8
Idebenone is expected to act as a neutralizer of these toxic forms of oxygen. Thus, idebenone is expected to have an antioxidant effect, and consequently prevent cellular damage.
Idebenone is optimized to dissolve in water and lipids and able to cross the mitochondrial membrane.
