Green Tea Extract
AntioxidantsKey Benefits
How It Works
EGCG (epigallocatechin gallate) inhibits catechol-O-methyltransferase (COMT), prolonging norepinephrine activity and increasing metabolic rate. It activates AMPK, enhances fat oxidation, crosses the BBB for neuroprotection, and is a potent free radical scavenger.
Dosage & Timing
Recommended Dosage
250-500 mg EGCG daily (or 500-1,000 mg green tea extract)
Best Time to Take
Morning or early afternoon with food (NOT on empty stomach)
Recommended Form
Decaffeinated green tea extract, always with food
Side Effects
Liver toxicity risk with high-dose extracts on empty stomach. Nausea, insomnia. ALWAYS take with food.
Drug Interactions
Interacts with nadolol, warfarin, and iron absorption. High doses affect liver-processed drugs. Contains caffeine.
What Does The Research Say?
Research supports modest metabolic and fat oxidation benefits. IMPORTANT: take with food due to hepatotoxicity risk of concentrated EGCG on empty stomach. Green tea drinking is safer than high-dose extracts.
