1) Protects the cells
Recent Kansas University research proved that EGCg content of catechin can protect your cells and DNA many times more effectively compared to other antioxidants such as vitamin E and C.
These researches utilized Ames testing method to determine catechin ability to protect DNA from oxidation. When Ames testing was imposed, EGCg is added to DNA and H2O2 is used to attack it.
The results showed that EGCg has strong antioxidant function with almost 68% DNA protecting ability, which is:
- 80 times better than vitamin C
- 10 times better than vitamin E

In vitro experiments have shown that green tea can suppress a series of nitrification. Experiments among animals also shown that green tea can suppress tumor of digestive tracts.
4) Suppresses carcinogens
Many cancer causing substances will be activated inside the cell via Cytochrome P450. However, catechin extract can suppress this reaction. The EGCg of catechin is especially excellent on this effect.
5) Suppresses Urokinase
Urokinase is a type of protein decomposing enzyme. Clinical experiment has discovered increased activity of this enzyme in different cancer patients. Urokinase has also been recognized as closely related to cancer cells metastasis (spreading).
