Ingredient research · Green Tea Extract
Green Tea Extract concentrates tea catechins, especially EGCG, and often contains caffeine. It may offer modest support for weight management and cardiometabolic health, but effects are generally small and product-dependent; unlike brewed tea, concentrated extracts can rarely cause liver injury, making formulation and use context especially relevant.
- Supports selected metabolic and liver markers in adults with non-alcoholic fatty liver disease.
- Supports ambulatory blood-pressure measures in obese women with prehypertension.
