What is in Green Coffee Extract?

Green coffee extract is a supplement and food product derived from green coffee beans.

This extract is sold as a pill and can be found online or in health food stores. A typical dose is between 60 to 185 milligrams per day.


What is a GCA Supplement?

GCA (Green Coffee Antioxidant) is a green coffee extract standardized at 50% Chlorogenic Acids. GCA can be formulated to meet your specification (ex: our “high-caf” version of 40% caffeine and 40% chlorogenic acids and our decaf version is <4% caffeine). GCA is naturally derived and if required, certified organic.


Green coffee bean extract comes from coffee beans that haven’t been roasted. The chlorogenic acid found in Green Coffee Beans is a natural phytochemical that is found in a wide array of plants, with very high concentrations in Green Coffee Beans. These compounds have been found to inhibit the release of glucose into the blood, particularly after meals, and appear to help people lose weight as a result.
