What It Actually Is
EGCG is a catechin — a type of antioxidant compound — concentrated from green tea leaves. It's one of the most-researched natural compounds in the weight-management space.
What Research Generally Shows
Studies on EGCG and green tea extract have looked at modest increases in calorie burning (thermogenesis) and fat oxidation, particularly when paired with caffeine. Effects tend to be moderate, not dramatic, and vary by individual.
Why It's Dosed At 500mg
500mg is a substantial, commonly-used dose in weight-management formulas, in the range used across several published studies on green tea catechins.
