Green tea extract is a bioflavonoid rich, potent extract used primarily for fighting free radicals. It contains a high content of polyphenols, which are a class of bioflavonoids. Green tea extract contains a potent antioxidant, EGCG, which is over 200 times more powerful than vitamin E in neutralizing the pro-oxidants and free radicals that attack lipids in the brain. This important ingredient, Epigallocatechin Gallate (EGCG), protects against digestive and respiratory infections, helps to block the cancer promoting actions of carcinogens, protects against high total and LDL cholesterol levels, and blocks the attachment of the bacteria associated with dental cavities to the teeth.

Green tea extract helps with thermogenesis and aids in the metabolism of fat. Known for years as a powerful antioxidant, it may also be helpful in shedding fat. The most obvious benefit to dieters is that it works without increasing the heart rate most often found in diet aids. The increased heart rate leaves dieters jittery and eventually, most dieters stop using the supplement and gain weight back. Now through using green tea extract, dieters get the weight loss benefits without any of the jittery effects, especially in obese individuals with hypertension and other cardiovascular complications.

Most nutritionists and physicians advise that weight loss can only be achieved through reducing food intake while increasing energy expenditure. Research shows that green tea extract seems to perform the energy expenditure required in dieters to lose weight although the mechanisms behind its action are unclear.

Green tea extract has shown as non-toxic in both acute dosages and high long-term dosage. Additionally, it has no potential for causing mutations, birth defects, and has no adverse effect on fertility, pregnancy, or nursing mothers.
