Green tea extract is a concentrated form of green tea leaves, typically standardized to contain high levels of catechins, particularly epigallocatechin gallate (EGCG). It is widely used in supplements for fat metabolism, antioxidant protection, and energy support.
For active individuals, green tea extract can support thermogenesis (calorie burning), improve endurance, and combat oxidative stress associated with intense workouts. Its mild caffeine content also contributes to increased alertness and performance without the jitters often linked to stronger stimulants.
This extract is popular in fat burners, pre-workout formulas, and wellness supplements aimed at enhancing metabolism and overall health.
