Coenzyme Q-10 (CoQ-10) is essential for adequate cellular energy production.  It is synthesized in the body but decreases with age and may be one of the reasons for the decreased energy that occurs as people age.  Co-Q10 is an oxidative reduction agent that functions in the energy-producing electron transfer chain in the mitochondria of cells.  It also serves as an important lipid-soluble antioxidant in the skin.  It protects against free radical damage from peroxides that damage collagen and elastin, thus protecting against a loss of elasticity in the skin and wrinkle formation
