Green Coffee Bean Extract
Chlorogenic acid-rich extract for metabolism and weight management
Also known as: GCBE • Chlorogenic Acid • Unroasted Coffee Extract
Overview
Green coffee bean extract is derived from unroasted coffee beans and is rich in chlorogenic acids — polyphenolic compounds that are largely destroyed during roasting. Unlike regular coffee, green coffee bean extract is standardized for chlorogenic acid content rather than caffeine. The primary interest centers on weight management and metabolic health. Chlorogenic acids may help reduce glucose absorption in the gut, lower blood sugar levels, and modestly boost fat metabolism. Beyond weight management, chlorogenic acids have demonstrated antioxidant, anti-inflammatory, and blood pressure-lowering properties in various studies.
Key Benefits
Weight Management
Chlorogenic acids may modestly reduce body weight by inhibiting glucose absorption and boosting fat metabolism.
Blood Sugar Support
Studies show chlorogenic acids can reduce post-meal blood sugar spikes.
Blood Pressure
Some research indicates it may help lower blood pressure.
Antioxidant Activity
Chlorogenic acids are potent antioxidants that help protect cells from oxidative damage.
