Chlorogenic Acid in Green Coffee Beans


Chlorogenic acids (CGA), are common polyphenols in plants. CGA are well absorbed in humans and have no reported side-effects in any sensible amount (3). They are considered Generally Recognized as Safe (GRAS) by the FDA.

CGA have strong effects in the body on insulin metabolism, utilization of body fat as fuel, and fat loss. CGA in green coffee beans, the top common source, range from about 60-90 mg/g. Amounts vary, however, by area grown, species, and year. Some green coffee beans haven’t much CGA, and zero effects on losing weight (1-3).

Roasting of coffee beans destroys the majority of the CGA. (4) So you cannot use roasted beans or ground coffee itself as a source of CGA. Hence all the hype using green, unroasted, coffee beans for weight reduction.

Rapid advances in analytic techniques over the past 10 years (5,6), have enabled good biochemists to separate beneficial effects of CGA from effects of caffeine. The chemistry is very complex, however (7). Consequently many organisations have made a complete mess of it.
Due to the huge profit potential in the burgeoning weight loss market, many CGA products have been improperly extracted and rushed to sale. Recently, the Federal Trade Commission found that even some products distributed under standardized brands, from good laboratories, have been adulterated by distributors. This adulteration produces worthless products with very low CGA.

Consequently, if you plan to purchase green coffee bean products, check out company selling them thoroughly. Many companies who never did the chemistry before, have jumped on the bandwagon and are producing useless diet supplements.

Real CGA is Effective

Real CGA does work. In both human and animal studies, CGA have demonstrated strong anti-inflammatory (7,8), blood sugar lowering (9,10) and body fat reduction (10-12) effects, all of which are disordered in overweight. In animal studies, CGA have clear anti-diabetic effects on insulin resistance and on lipid metabolism (11-14).

Glucose-6-phosphatase, for instance, is the major enzyme for releasing glucose into the blood from the liver. This enzyme, helps regulate blood glucose in active young adults.

In older people, over age 35 however, it triggers an unhealthy after-meal boost in blood glucose. This surge becomes progressively worse as we get older. CGA have been demonstrated in a variety of controlled trials to control glucose-6 phosphatase and lower blood glucose in vitro, and in live animal, and human, trials (23-26).

CGA powder can be added to ground coffee after roasting with significant benefits for weight reduction (27). Keurig and similar systems can prepare delicious coffee at a lower temperature than expresso machines, and quicker than drip percolators. Consequently, they provide a less destructive vehicle for delivery of CGA from powder added to the pod.

CGA added to coffee before brewing coffee also yields a much better tasting coffee, because CGA provide much of the taste and aroma of coffee in any case. We use 200 mg of potent CGA powder per 8-ounce cup of joe, tipped into the central hole made by the Keurig machine before brewing. Drink this java daily in good faith that it will help you maintain recommended weight.
