What is Green Coffee Bean Extract?

Green coffee bean extract is derived from unroasted coffee beans (Coffea arabica or Coffea canephora). Unlike regular coffee beans, which are roasted to develop their flavor and aroma, green coffee beans retain higher levels of chlorogenic acid, a bioactive compound responsible for many of the extract’s health benefits.

Key features of green coffee bean extract include:

• High chlorogenic acid content: Typically 40–50% in standardized extracts.
• Low caffeine content: Contains less caffeine than roasted coffee, making it gentler on the body.
• Natural and plant-based: Free from synthetic additives and GMOs.

Green coffee bean extract is available in capsule, tablet, and powder forms, with a recommended dosage of 400–800 mg per day.
