Green tea extract is one of the most studied natural compounds for supporting fat metabolism. Its main active component, EGCG, works synergistically with caffeine to help support fat oxidation and energy expenditure.*
- EGCG + Caffeine: Synergistic effect on fat oxidation and metabolic rate.*
- Exercise Synergy: Benefits are stronger when paired with physical activity.
- Modest Results: Works best as part of a calorie-controlled diet and active lifestyle.*
- Convenient Form: Standardized extracts provide consistent dosing of active compounds.
How Green Tea Extract Supports Fat Burning
EGCG inhibits an enzyme that breaks down norepinephrine, prolonging its effects on fat metabolism. It also activates thermogenesis and may improve fat oxidation, especially during exercise.*
