It has been known for ages that green tea extracts will help with weight loss, perhaps cancer and it contains many elements critical to help the human body function at top peak and to remain healthy. Green Tea is known to contain anti-aging properties because it contains many antioxidants known as polyphenols which are the greatest number of antioxidants that green extracts contain. One green tea extract will contain as much green tea as a cup of green tea. It is obviously a much more concentrated form. Green tea will fight free radical damage which will damage the body at the cellular level. The green tea extract will keep cells fresh and rejuvenated. This, in turn, keeps the skin pliable and young-looking. This is how green tea extract can fight the aging process on all levels. It may even help to fight cancer by replacing stem cells when they die. The body must keep a balance of stem cells to remain cancer free and when this balance is disrupted cancerous cells may invade. The green tea contains antioxidants (as we mentioned before) that may help the reproduce stem cells to keep the balance where it needs to be. This will prevent cancer from forming and proliferating in the body.
