The antioxidants contained in green tea help resist aging. Because of the human body's metabolic processes, if overly oxidized, a large amount of free radicals are produced, which can easily cause aging and also damage cells. SOD (Superoxide Dismutase) is a free radical scavenger that can effectively remove excess free radicals and prevent damage to the human body caused by free radicals. The catechins in green tea can significantly enhance the activity of SOD and remove free radicals.
