About this ingredient
Ingredients
Green Tea Extract is a concentrated botanical ingredient derived from the leaves of Camellia sinensis. It naturally contains tea catechins, including epigallocatechin gallate (EGCG), as well as caffeine and other tea-derived compounds. The exact catechin concentration, EGCG content, caffeine level, extract ratio, and additional ingredients vary by manufacturer and product.
Green Tea Extract is a concentrated extract made from the leaves of Camellia sinensis, the same plant used to produce green, black, and oolong tea. Green tea is prepared without the fermentation used for black tea, helping retain its characteristic tea polyphenols and catechins.
Green Tea Extract naturally provides catechins and other polyphenols, along with varying amounts of caffeine. EGCG is one of the major catechins commonly associated with green tea extracts. Products may be standardized to total catechins, EGCG, or other compounds, while some formulations specify their caffeine content.
Green Tea Extract is commonly included in antioxidant, metabolism, weight-management, energy, and active-lifestyle nutritional formulas. Research suggests that the catechins and caffeine in green tea may have a modest effect on body weight, although results can vary according to the product and individual factors.
Because concentrated green tea extracts can contain substantial amounts of caffeine and have been associated, rarely, with liver problems, consumers should check the product label and follow the recommended serving. People taking medicines should also discuss green tea supplements with a healthcare professional because interactions are possible.
