ObjectiveA proprietary natural fiber complex (Litramine IQP G-002AS) derived from Opuntia ficus-indica, and standardized on lipophilic activity, was previously shown in preclinical and human studies to reduce dietary fat absorption through gastrointestinal (GI) fat binding. Here, we investigated the efficacy and safety of IQP G-002AS in body weight reduction.Design and MethodsOne hundred twenty-five overweight and obese adults participated in the study. Subjects were advised on physical activity, and received nutritional counseling, including hypocaloric diet plans (30% energy from fat and 500 kcal deficit/day). After a 2-week placebo run-in phase, subjects were randomized to receive either 3 g/day of IQP G-002AS (IQ) or a placebo. The primary endpoint was change in body weight from baseline; secondary endpoints included additional obesity measures and safety parameters.ResultsOne hundred twenty-three subjects completed the 12-week treatment phase (intention-to-treat (ITT) population: 30 male and 93 female; mean BMI: 29.6 ± 2.8 kg/m2 and age: 45.4 ± 11.3 years). The mean body weight change from baseline was 3.8 ± 1.8 kg in IQ vs. 1.4 ± 2.6 kg in placebo (P < 0.001). More IQ subjects lost at least 5% of their initial body weight compared to placebo (P = 0.027). Compared with placebo, IQ also showed significantly greater reduction in BMI, body fat composition, and waist circumference. IQ was well tolerated with no adverse reactions reported.ConclusionsThese results suggest that the natural fiber complex Litramine IQP G-002AS is effective in promoting weight loss.
Objective: The safety and efficacy of IQP-PV-101, a proprietary extract of Phaseolus vulgaris, on weight management in two phases was evaluated here. The weight loss (WL) phase was conducted over 12 weeks and the weight maintenance (WM) phase took 24 weeks. Methods: In the double-blind WL phase, subjects were randomized to receive either IQP-PV-101 or placebo. All subjects adhered to a mildly hypocaloric diet. Body weight and other body composition parameters were measured at baseline and every 4 weeks thereafter. During the single arm, open label WM trial, energy intake was ad libitum. Efficacy parameters were measured at baseline, week 12 and week 24. Results: At the end of the WL study, the IQP-PV-101 group lost a mean of 2.91 6 2.63 kg in body weight compared with 0.92 6 2.00 kg in the placebo group (P < 0.001). During the WM phase, 36 out of 49 subjects (73.5%) were able to maintain their weight, even without dietary restrictions. No serious or related adverse events were reported over the combined period of 36 weeks. Conclusions: Results indicate that IQP-PV-101 is safe and effective for weight loss and maintenance.
BackgroundCactus (Opuntia ficus-indica) fiber was shown to promote weight loss in a 3-month clinical investigation. As demonstrated by in vitro studies, cactus fiber binds to dietary fat and its use results in reduced absorption, which in turn leads to reduced energy absorption and ultimately the reduction of body weight.ObjectiveThe objective of our study was to elucidate the dietary fat binding capacity of cactus fiber through determination of fecal fat excretion in healthy volunteers.Subjects and MethodsThis clinical investigation was performed as a double-blind, randomized, placebo-controlled, crossover study in healthy subjects for a period of approximately 45 days. Twenty healthy volunteer subjects were randomized to receive cactus fiber or placebo, 2 tablets thrice daily with main meals. All subjects were provided with meals during the study period (except washout) according to a standardized meal plan, with 35% of daily energy need coming from fat. Two 24-hour feces samples were collected during both the baseline and treatment periods for analysis of the fat content.ResultsCactus fiber showed an increased fecal fat excretion compared with placebo (mean [SD] = 15.79% [5.79%] vs 4.56% [3.09%]; P < 0.001). No adverse events were reported throughout the study period.ConclusionsCactus fiber has been shown to significantly promote fecal fat excretion in healthy adults. The results of our study support the hypothesis that cactus fiber helps in reducing body weight by binding to dietary fat and increasing its excretion, thus reducing dietary fat available for absorption.

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 (pU = 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.

Irritable bowel syndrome (IBS) is a functional bowel disorder of unknown aetiology. There is currently no known cure, and pharmacological interventions are usually targeting symptomatic relief, where natural and herbal remedies also play a role. This study aimed to evaluate the benefit and tolerability of IQP‐CL‐101 in symptomatic IBS relief. A double‐blinded, randomised, placebo‐controlled trial was conducted over 8 weeks. A total of 99 subjects fulfilling ROME‐III criteria for IBS were randomised into two groups, given either two IQP‐CL‐101 softgels or matching placebo twice daily before main meals. The primary endpoint was the difference in change of IBS Symptom Severity Score (IBS‐SSS) after an 8‐week intake of IQP‐CL‐101 compared to placebo. After 8 weeks, subjects on IQP‐CL‐101 showed a significant reduction in IBS‐SSS (113.0 ± 64.9‐point reduction) compared to subjects on placebo (38.7 ± 64.5‐point reduction) (p < 0.001). A significant improvement could be seen as early as 4 weeks. No serious adverse events were reported throughout. IQP‐CL‐101 can be considered beneficial in the improvement of IBS symptom severity, regardless of IBS type, and therefore able to improve quality of life in patients suffering from abdominal pain and discomfort. © 2017 The Authors.

Sedentary lifestyle and caloric overconsumption are the key determinants of the escalating obesity prevalence. Reducing dietary fat absorption may help to induce a negative energy balance and thus help in managing weight problem. Apart from approved drug therapies, weight problems may also be aided with alternative and natural treatments. This paper compiled and reviewed the efficacy and safety of Litramine IQP-G-002AS, an Opuntia ficus-indica (OFI) derived fiber, in reducing dietary fat absorption and promoting weight loss. Evidence reviewed shows that Litramine IQP-G-002AS displays efficacy in promoting fat excretion and weight loss in four randomized, placebo-controlled clinical studies (including an unpublished pilot study). With a daily dosage of 3 g over a seven-day period, Litramine IQP-G-002AS showed an increased faecal fat excretion compared with placebo (15.8% (SD 5.8%) versus 4.6% (SD 3.1%); P < 0.001). In a 12-week study, significant greater weight loss (3.8 kg (SD 1.8 kg) versus 1.4 kg (SD 2.6 kg); P < 0.001) was observed in overweight and obese subjects treated with Litramine IQP-G-002AS as compared to placebo. No relevant gastrointestinal side effects have been reported for Litramine IQP-G-002AS at the dosages studied.

The mean body weight change from baseline was 3.8 6 1.8 kg in IQ vs. 1.4 6 2.6 kg in placebo (P < 0.001). More IQ subjects lost at least 5% of their initial body weight compared to placebo (P ¼ 0.027). Compared with placebo, IQ also showed significantly greater reduction in BMI, body fat composition, and waist circumference. IQ was well tolerated with no adverse reactions reported. Conclusions: These results suggest that the natural fiber complex Litramine IQP G-002AS is effective in promoting weight loss.
Background. Litramine (IQP-G-002AS) was shown to be effective and safe for weight loss in overweight and obese subjects. However, long-term effectiveness on maintenance of body weight loss has yet to be ascertained. Objective. To assess effect of Litramine on maintenance of body weight loss. Methods. A double-blind, randomised, placebo-controlled trial on overweight and obese patients was conducted over two sites in Germany for 24 weeks. Subjects with documented previous weight loss of 3% over the last 3–6 months were randomised to groups given either Litramine (3 g/day) or a matching placebo. Primary endpoints were difference of mean body weight (kg) between baseline and end of study and maintenance of initially lost body weight in verum group, where maintenance is defined as ≤1% weight gain. Results. Subjects who were taking Litramine lost significantly more body weight compared to the subjects taking placebo who gained weight instead (−0.62 ± 1.55 kg versus 1.62 ± 1.48 kg, p < 0.001). More importantly, 92% of subjects in Litramine group were able to maintain their body weight after initial weight loss, versus 25% in placebo group. No serious adverse events were reported throughout. Conclusion. Litramine is effective and safe for long-term body weight maintenance. Trial Registration. This trial is registered with Clinicaltrials.gov identifier: NCT01505387.
