Each capsule contains: 500 mg of green tea extract standardized to 50% polyphenols, and caffeine less than 5%   Recommended Dosage: 2 –3 capsules per day   Green tea extract is high in polyphenols. Of the three type of tea (green, black and oolong), green tea contains the highest amount of polyphenols. The four most important from the medical viewpoint are epicatechin, epigallocatechin, epicatechin gallate and epigallocatechin gallate (EGCG). About half of the polyphenols in green tea are EGCG. Green tea has many beneficial health properties including: Anti-oxidant and free radical inhibitor activity One of the polyphenols that green tea is rich in – epigallocatechin gallate – has been shown to be more than 200 times more effective as an free radical inhibitor than vitamin E in protecting lipids from peroxidation. Anti-bacterial and anti-viral activity Green tea extract is a very potent bactericidal against many bacteria, including Bordetella pertussis, Staph. aureus, S. epidermidis, Vibrio cholerae, V. parahaemolyticus, V. mimicus, Campylobacter jejuni, Plesiomonas (Aeromonas) shigelloides, and even enteropathological E. coli. The bacterium responsible to a large extent for plaque formation and caries – Streptococcus mutans - is inhibited by green tea. A 1mcg per ml solution of EGCG strongly inhibited the influenza virus. However, probiotic bacteria, such as Lactobacillus acidophilus is not inhibited but increased. Anti-platelet aggregation[1] and reduction of blood cholesterol levels The anti-platelet aggregation activity of green tea extract rivals that of Ginkgo biloba or aspirin.  Decreasing the incidence of cancer For all types of cancer, but in particular for GI cancers, such as esophageal, liver and stomach. Many animal studies support the epidemiological studies in humans: mammary (rat), and skin (mouse) cancers. Cigarette smokers who consumed green tea had a 45% lower probability of cancer than those who didn’t drink green tea.  EGCG killed cancer cells derived from samples of human skin, lymphatic and prostate, without killing normal cells. Aid in weight loss programs In a recent paper[2] green tea extract was administered to a group of healthy males. Another group took caffeine (green tea contains some caffeine) and a third group took a placebo.   It was found the men who took the extract burnt more fat than those who took the caffeine alone or those who took the placebo. There was no increase in heart rate nor any other side effects.   Therefore the increased energy expenditure cannot be attributed to fat. This is due to a number of ingredients in the tea, including the polyphenols. The increase in energy expenditure amounted to 4% - which although not large can provide support in a complete weight loss program. Combined with a weight loss program such as the Atkins diet and exercise, supplementation with green tea can provide the edge in losing weight.   (Note we have increased the polyphenols by a factor of 2-3 that of the clinical trial, to provide more of the health benefits of green tea) [1] Ali M. et al A potent thromboxane formation inhibitor in green tea leaves Prostaglandins Leukot Essent Fatty Acids 40: 281-3, 1990 [2] American Journal of Clinical Nutrition: 70(12): 1040-45, 1999
