From Green Coffee Extract

Green coffee extract is made from unroasted coffee beans. The beans are typically extracted using water or a solvent to isolate compounds like chlorogenic acids. These compounds are then concentrated to create the final extract.

Manufacturers add green coffee extract primarily for its chlorogenic acid content, which is believed to contribute to its health effects. It is most often found in beverages, particularly caffeinated sparkling waters, where it can act as a source of natural caffeine and antioxidants.

Green coffee extract is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of caffeine, which can cause jitteriness or sleep disturbances in sensitive individuals. Some studies suggest chlorogenic acids may have a modest effect on blood sugar and weight management, but research is ongoing and results are mixed. JECFA has evaluated green coffee extract.
