Uses of green tea are still being explored by medical science in research that may take many years. The antioxidant properties (and a host of others) of green tea are becoming well known around the world, especially in the diet and health markets. Green tea weight loss extract can be purchased easily in liquid and pill form, but whichever way it is taken, you will burn calories naturally. It has a wide range of benefits for the human metabolism but first and foremost, it has great anti-aging properties, accelerating cell regeneration and slowing the oxidation process in the system. While this is an added benefit, the green tea weight loss products rely on its ability to work as a natural laxative, and use it as a method of purging toxins from the system.
