OPA Green Coffee Bean Extract 800 mg – 50% Chlorogenic Acids, 20 mg Natural Caffeine, Dietary Supplement, 60 Veggie Capsules
OPA Green Coffee Bean Extract gives you 800 mg of extract from unroasted green coffee beans in each veggie capsule, standardized to 50% chlorogenic acids (GCA). Chlorogenic acids are plant compounds that occur naturally in coffee beans, and the label lists them as GCA (green coffee antioxidant). Each capsule also has about 20 mg of naturally occurring caffeine, which is less than half a cup of coffee. There's no added sugar and no added stimulants.
Adults take one capsule twice a day before meals. A bottle of 60 capsules lasts 30 days.
