Green tea (Camellia sinensis) is the most consumed beverage in the world after water, and has important medicinal value in Eastern cultures. It is rich in polyphenols, which show strong antioxidant properties. The major polyphenols in green tea are catechins, particularly epicatechin, epicatechin gallate, epigallocatechin 3-gallate, and proanthocyanidins. Of special interest is epigallocatechin-3-0-gallate (or EGCg), a polyphenol that makes up about 10–50% of the total catechin content and is the most powerful of the catechins, with antioxidant activity about 25–100 times more potent than vitamins C and E. Natural Factors Green Tea Extract contains highly purified polyphenols rich in natural green tea catechins.
As antioxidants, green tea catechins scavenge free radicals, prevent free radical damage, and enhance antioxidant defense systems by stimulating antioxidant enzyme activity such as glutathione peroxidase and catalase. The antioxidant polyphenols in green tea may also help protect against the oxidation of LDL (“bad”) cholesterol, a major contributor to atherosclerosis.
Research demonstrates that green tea helps guard against cardiovascular disease. Green tea lowers total cholesterol levels and improves the cholesterol profile (the ratio of LDL cholesterol to HDL cholesterol), reduces platelet aggregation, and lowers blood pressure. The polyphenols in green tea have also been shown to stimulate the production of several immune system cells, and have antibacterial properties, even against the bacteria that cause dental plaque.
Green tea extract also supports healthy weight loss by decreasing the absorption of fat in the digestive tract. It stimulates thermogenesis, where the body turns fat into energy, better than caffeine or ephedrine and without increasing heartrate.
Natural Factors Green Tea Extract is standardized to provide optimal levels of polyphenols, including catechins and EGCg and offers potent antioxidant support.
