Product Information

A study on healthy volunteers compared absorption of a single 400-mg dose of green tea polyphenols as non-complexed standardized extract Greenselect or as the same extract complexed with phosphatidylcholine – Greenselect Phytosome. Peak blood concentration of EGCG from the phytosome, measured over a period of six hours, was approximately double that of the non-complexed green tea extract.*

Green tea polyphenols are powerful antioxidants due to their particular flavonoid structures, and their glutathione-sparing activity has been well documented.* Green tea polyphenols also help maintain the body's normal inflammatory response.*

Green tea has a thermogenic effect.* Extracts of EGCG increase energy expenditure and fat oxidation, thus essentially burning calories.* Greenselect Phytosome was tested in obese subjects (n=100) of both genders on a low-caloric diet; 50 subjects were assigned to the green tea extract plus the low-calorie diet, while the other 50 subjects followed the low-calorie diet only. After 90 days of treatment, significantly greater improvement in weight and body mass index was observed in the Greenselect Phytosome group compared to the diet-only group.*

Human studies of green tea's weight management properties resulted in greater calorie burning by individuals taking the extract.* Although some of the effects of green tea extract have been attributed to the caffeine content, a study found increased metabolic rate and greater fat metabolism in study subjects taking green tea extract compared to those taking a placebo, even though the green tea extract did not contain caffeine.*
