Benefits of technology

The green coffee extract effectively reduces body weight, body mass index, and increases muscle mass to fat mass ratio, demonstrating its potential in managing type 2 diabetes and obesity by modulating glucose metabolism and inhibiting glucose production in the liver.

Problems solved by technology

In addition, the choice of raw material and the extraction conditions provide an extract containing no cafestol or kahweol, constituents of coffee which can increase the risk of cardiovascular disease.

In some embodiments, the green coffee extract comprises, Nutritional profiles of a green coffee extract (Svetol® green coffee extract, NATUREX). Nutritional analyses were conducted according to the European pharmacopoeia. Table 4 shows the nutritional value of the green coffee extract used in the examples reported herein (Svetol® green coffee extract, NATUREX).

HPLC Chromatogram of the Green Coffee Extract (Svetol® Green Coffee Extract, NATUREX)

[0051]The high-pressure liquid chromatography chemical fingerprint for a green coffee extract (Svetol® green coffee extract, NATUREX) is presented in FIG. 6. The method for performing this analysis was as follows: HPLC-DAD was achieved using a column RP-C18 (5 μm-250×4.6 mm) at 55° C. The flow rate was 0.8 mL / min, and the elution was monitored at 330 nm. The mobile phases were (A) distilled water+H3PO4 0.002M, and (B) acetonitrile. A solution of 100% A was maintained during 8 min, increased by linear gradient to 35% A and 65% B by volume after 35 min total time; followed by a linear gradient of 100% A after maintaining this composition for 10 min; the system was then re-equilibrated to the initial composition. The content of CGA from 10 batches of green coffee extract (Svetol® green coffee extract, NATUREX) reported as mean±standard deviation (SD) is shown in Table 5.

Abstract

A method of controlling body weight in humans by administering an amount of decaffeinated green coffee extract effective to treat a subject. A preferred green coffee extract contains a ratio of 4-caffeoylquinic acid (4-CQA) to total chlorogenic acids (tCGA) (5-CQA / tCGA) of from about 0.1 to about 0.2. More preferably, the green coffee extract comprises from about 6% to about 8% of 4-caffeoylquinic acid and has a total chlorogenic acid concentration that exceeds about 45%. A preferred method of administration consists of administering the green coffee extracts is a dosage of about 200 mg twice a day prior to meals on an empty stomach.

Description

[0001]This application is a continuation-in-part and claims the benefit of a non-provisional U.S. patent application Ser. No. 12 / 263,292 filed on Oct. 31, 2008.FIELD OF THE INVENTION[0002]The present invention relates to dietary supplements comprising a green coffee extract and methods relating to the administration of green coffee extract.BACKGROUND OF THE INVENTION[0003]The prevalence of obesity (BMI≧30 kg / m2) continues to be a health concern for adults, children and adolescents in the United States. Data from the NHANES survey shows that among adult men the prevalence of obesity increased from 31.1% in 2003-04 to 32.2% in 2007-08, a small but not statistically significant change. Among adult women, the prevalence of obesity increased from 33.2% in 2003-04 to 35.5% in 2007-08, again a small but not significant change (Ogden et al. Gastroenterology 2007; 132 (6):2087-2102; Flegal et al. JAMA 2009; 303 (3):235-241). In Europe, the prevalence of obesity has increased by 10 to 38%, de...
