This product contains pure green tea extract with no added ingredients. Each capsule has a minimum NRV of 45% EGCG and 95% Polyphenols. The EGCG catechin is the main active ingredient in green tea. Green tea originates from green tea leaves called Camellia sinensis. Unlike black tea leaves, which oxidase and wilt from the minute they are picked, green tea leaves do not oxidase and retain the original nutrients. Green tea is becoming a widely consumed hot beverage as an alternative drink to black tea. For individuals who consume milk and sugar in traditional black teas, the rise and variety of green teas have helped to reduce their daily refined sugar consumption. Most of the current research being conducted on the health benefits of green tea consumption relate closely to the flavanoids and catechins contained in the leaf itself, such as the Epigallocatechin gallate (EGCG).
