IQP-GC-101 Reduces Body Weight and Body Fat Mass: A Randomized, Double-Blind, Placebo-Controlled Study

IQP-GC-101 is a patented blend of the standardized extracts of Garcinia cambogia, Camellia sinensis, unroasted Coffea arabica, and Lagerstroemia speciosa. These individual ingredients of IQP-GC-101 have each shown promise in promoting weight loss; however, the efficacy of the blend has not been established. This randomized, placebo-controlled, double-blind, parallel group study conducted over 14 weeks (including a 2-week run-in phase) aimed to investigate the efficacy and safety of IQP-GC-101 in reducing body weight and body fat mass in overweight Caucasian adults. Subjects took three IQP-GC-101 or placebo tablets, twice a day, 30 min before main meals. All subjects also adhered to a 500 kcal/day energy deficit diet with 30% of energy from fat. Ninety-one overweight and mildly obese subjects (46 in the IQP-GC-101 group, 45 in the placebo group) completed the study. After 12-week intervention, IQP-GC-101 resulted in a mean (±SD) weight loss of 2.26 ± 2.37 kg compared with 0.56 ± 2.34 kg for placebo (p(U) = 0.002). There was also significantly more reduction in body fat mass, waist circumference, and hip circumference in the IQP-GC-101 group. No serious adverse events were reported. The use of IQP-GC-101 has been shown to result in body weight and body fat reduction in the current study, with good tolerability. © 2014 InQpharm Group Sdn Bhd.
