✓ What the Science Says
Green tea extract is rich in catechins, particularly epigallocatechin gallate (EGCG), which has been shown to support weight loss and improve metabolic health. It may also provide antioxidant benefits and support cardiovascular health.
✗ What It Doesn't Do
Green tea extract is often marketed as a miracle fat burner or a cure-all for various health issues, but it does not directly cause significant weight loss without lifestyle changes such as diet and exercise. Claims of it being a substitute for a healthy lifestyle are misleading.
