Mega Green Tea Extract 98% Polyphenols 100 caps.

The active constituents in green tea are polyphenols, with an antioxidant called epigallocatechin-3-gallate (EGCG) being the most powerful. The antioxidant activity of EGCG is about 25-100 times more potent than vitamins C and E. One cup of green tea may provide 10-40 mg of polyphenols and has antioxidant effects that are greater than a serving of broccoli, spinach, carrots, or strawberries.

The botanical extract in Mega Green Tea Extract has been concentrated and dual standardized to ensure the highest quality, consistency and biological activity. This advanced extract contains 98% total polyphenols (710.5 mg per capsule) and 45% Epigallocatechin gallate (EGCG) (326.25 mg per capsule).

Benefits of Green Tea

Cancer Prevention

Published research shows that EGCG is the most potent cancer cell suppressing polyphenol found in green tea. Some noteworthy studies on green tea include:

• When non-Hodgkins lymphoma cells were transplanted into mice, green tea prevented 50% of the tumors from taking hold and significantly inhibited growth of the tumors (Leukemia 2000 Aug;14(8):1477-82).

• Green tea was shown to help protect against the progression of atrophic gastritis in Japanese men (Scand J Gastroenterol 2000 May;35(5)476-81).

• Phenol sulfotransferases are involved in cancer growth, and green tea extract was shown to inhibit this activity in a human colon cancer call line (Biol Pharm Bull 2000 Jun;23(6):695-9).

Weight Loss

The main substances in green tea that are believed to aid in weight loss are catechins and caffeine. Catechins are water-soluble, antioxidant compounds which include epigallocatechin gallate, epigallocatechin, epicatechin gallate. “The catechins (especially EGCG) and caffeine in green tea extract appear to work together to increases 24-hour energy expenditure, induce thermogenesis and promote fat burning in humans without increasing heart rate or adversely affecting the cardiovascular system.”^1,2. Researchers know that green tea extract promotes thermogenesis above and beyond its caffeine content.³ They have been aware for several years that compounds in green tea increase caffeine’s calorie-burning effects. What those compounds are was a mystery until Japanese researchers decided to look into it in 2004. They divided green tea into its various components and investigated how catechins, theanine, caffeine, and green tea powder itself affect weight gain in female mice.⁴ They found that all the components suppressed weight gain. Green tea powder, catechins, and theanine also reduced triglyceride levels. The researchers concluded that not only can caffeine help prevent weight gain and fat accumulation, but theanine can, too.
