Green tea supplementation has been shown to have several health properties including an increase in plasma antioxidant which will lead to a lowering of oxidative damage (11, 12), decreased blood pressure (13, 14) and it can protect against coronary atherosclerosis (15). Other health effects that green tea can have includes a lowering of cholesterol, an increase of insulin activity (16) and a regulation of blood glucose levels which can help reduce body fat.
