What is Green Coffee Bean Extract?

Just as black tea is made by processing green tea leaves from their original state, ordinary coffee is made by roasting green coffee beans. This processing alters the chemical makeup of the plant product. In an analogy to the medicinal study of green tea , an extract made from green coffee beans is undergoing increasing investigation as a possible health-promoting supplement.
