The Effect of an Innovative Combination of Bergamot Polyphenolic Fraction and Cynara cardunculus L. Extract on Weight Gain Reduction and Fat Browning in Obese Mice

obesity is one of the world's most serious public health issues, with a high risk of developing a wide range of diseases. as a result, focusing on adipose tissue dysfunction may help to prevent the metabolic disturbances commonly associated with obesity. nutraceutical supplementation may be a crucial strategy for improving WAT inflammation and obesity and accelerating the browning process. the aim of this study was to perform a preclinical "proof of concept" study on bergacyn (R), an innovative formulation originating from a combination of bergamot polyphenolic fraction (BPF) and Cynara cardunculus (CyC), for the treatment of adipose tissue dysfunction. In particular, bergacyn (R) supplementation in WD/SW-fed mice at doses of 50 mg/kg given orally for 12 weeks, was able to reduce body weight and total fat mass in the WD/SW mice, in association with an improvement in plasma biochemical parameters, including glycemia, total cholesterol, and LDL levels. In addition, a significant reduction in serum ALT levels was highlighted. the decreased WAT levels corresponded to an increased weight of BAT tissue, which was associated with a downregulation of PPAR gamma as compared to the vehicle group. bergacyn (R) was able to restore PPAR gamma levels and prevent NF-kB overexpression in the WAT of mice fed a WD/SW diet, suggesting an improved oxidative metabolism and inflammatory status. these results were associated with a significant potentiation of the total antioxidant status in WD/SW mice. finally, our data show, for the first time, that bergacyn (R) supplementation may be a valuable approach to counteract adipose tissue dysfunction and obesity-associated effects on cardiometabolic risk.
