Efficacy of Citrus Extract in weight management

French researchers from Fytexia company investigated the efficacy and safety effects of Sinetrol-XPur (polyphenolic citrus dry extract) in weight management; metabolic parameters; and inflammatory, glycemic and oxidative status, in order to reduce abdominal fat, waist and hip circumference. The results were published on April 2013 issue of Phytotherapy Research journal.

In a 12-week, randomized, double-blind, placebo-controlled trial, Sinetrol-XPur was given to overweight subjects twice daily with meals in the tested group (N = 47) versus a placebo group (N = 48). Waist and hip circumference and abdominal fat were decreased in the Sinetrol-XPur group as compared with the placebo group (p < 0.0001) (-5.71% vs -1.56% for waist, -4.71% vs -1.35% for hip and -9.73% vs -3.18% for fat). Inflammatory markers were reduced (C-reactive protein: -22.87% vs +61%; fibrinogen: -19.93% vs -1.61%, p < 0.01). Oxidative stress was lowered as seen by the reduction of malondialdehyde (-14.03% vs 2.76%) and the increase in superoxide dismutase and glutathione (17.38% vs 2.19% and 4.63% vs -2.36%, respectively, p < 0.01). No adverse effects were observed. Kidney, liver, and lipid panels remained unchanged.

These results indicated that Sinetrol-XPur supplementation is a viable option for reducing abdominal fat, waist and hip circumference, and body weight and for improving inflammatory, glycemic, and oxidative status in healthy overweight individuals.
