FAT LOSSLIMITED
Green Tea Extract (EGCG)
Tiny metabolic bump. High-dose EGCG carries liver risk.
EFFECTIVE DOSE
≤500 mg EGCG/day if used; take with food
HOW IT WORKS
Catechins modestly increase catecholamine-driven thermogenesis.
WHAT THE EVIDENCE SUPPORTS
- Very small fat-loss/metabolic signal in some trials
WHAT TO LOOK OUT FOR
- High-dose EGCG (>800 mg/day) linked to rare but real hepatotoxicity — never take fasted.
- Effect size in humans is tiny compared to marketing.
SIDE EFFECTS
- Liver enzyme elevation, GI upset
