Supplementation of green coffee bean extract in healthy overweight subjects increases lean mass/fat mass ratio: A randomized, double-blind clinical study.


ABSTRACT:

Objective

In this study, we have demonstrated that supplementation of a complex of chlorogenic acid isomers (CGA-7TM) could significantly mitigate the risk of obesity in healthy overweight subjects.

Method

In a double-blind, placebo-controlled clinical study, healthy overweight (body mass index ⩾ 25 to <30 kg/m2) male and female subjects (N = 71) were randomly allocated to receive 500 mg CGA-7 or placebo daily for 12 weeks. Changes in body weight and body mass index were recorded alongside vital signs and anthropometric measurements at week 4, 8 and 12. Body composition was assessed at baseline and the end of treatment using dual-energy X-ray absorptiometry. Safety analysis included serum biochemical and haematological assessments and measurement of vital signs. In addition, any adverse or serious adverse events were recorded during the study.

Results

Sixty subjects completed the study. Mean body weight and body mass index were significantly reduced in CGA-7 group as compared to placebo (p < 0.001). CGA-7 group showed significant changes in body fat (%), fat mass and lean mass in comparison with placebo group (1.38% ± 1.4% vs -0.22% ± 0.86%, 1.97 ± 1.44 kg vs -0.39 ± 1.31 kg; 0.81 ± 1.20 kg vs -0.13 ± 0.97 kg, p < 0.001). Consumption of CGA-7 significantly improved the serum lipid profile. Importantly, CGA-7 consumption in humans had no adverse effects and was well tolerated during the study. The blood biochemical and haematological parameters marginally varied in the treatment groups throughout the study.

Conclusion

To conclude, this study provides scientific validation of the functionality of green coffee bean extract and recommends the safety of the supplementation in healthy individuals.
