Green tea catechins — especially EGCG (epigallocatechin gallate) — boost metabolic rate by 3-8% and increase fat oxidation by 10-17%. EGCG inhibits the enzyme that breaks down norepinephrine, keeping metabolic-boosting signals active longer. Combined with caffeine, it creates a synergistic thermogenic effect.
Take 400-500mg green tea extract (standardized to 50% EGCG) daily, or drink 3-5 cups of green tea. Take with meals to reduce nausea. Best taken in the morning or before exercise for maximum fat-burning effect.
Contains caffeine — may cause insomnia if taken late. Can cause nausea on empty stomach. High doses (>800mg EGCG) linked to liver stress. Avoid with blood thinners.
