Coenzyme Q10 is a natural antioxidant that offers benefits in the treatment and prevention of certain chronic diseases. As a coenzyme, the nutrient plays an important role in the production of energy at the cellular level. It also protects the body against free radical damage thus slowing the progress of ageing and age-related degenerative diseases. Studies have shown that CoQ10 may lower the risk of heart failure, support immune system and reduce muscular fatigue. Apart from that, CoQ10 intake is also recommended for those on cholesterol-lowering medications as they may deplete natural levels of CoQ10 in the body.
