Background: Metabolic syndrome is characterized by the impairment of several metabolic and haemodynamic parameters. Several natural compounds have just demonstrated to improve glucose and lipid levels in humans. Aim: To assess the short-term glucose and lipid-lowering effects of a combination of nutraceuticals based on Lagerstroemia speciosa, Berberis aristata, Curcuma longa, alpha-lipoic acid, chrome picolinate and folic acid in patients with post-menopausal incident metabolic syndrome. Methods: We performed a double-blind, placebo-controlled, parallel-group, randomized clinical trial by enrolling 40 women in primary prevention of cardiovascular disease and affected by metabolic syndrome occurred in menopause. After 2-week run-in period of dietary standardization, enrolled patients were allocated to active treatment or placebo for 8 weeks. Data related to lipid pattern, insulin resistance, liver function and hsCRP were obtained at the beginning and at the end of the study. Results: No patient experienced any subjective or laboratory adverse event. During the study, there were no significant changes in waist circumference, body mass index, blood pressure and low-density lipoprotein cholesterol in either treatment groups. Subjects randomized to nutraceutical treatment experienced a significant improvement in triglycerides (TG=-32.2%), high-density lipoprotein cholesterol (HDL-C= +5.7%), fasting plasma insulin (FPI=-14.1%), and in homeostasis model assessment of insulin resistance (HOMA-Index=-27.3%) versus the baseline values, as welle as compared to the placebo-treated group. Conclusions: The tested nutraceutical compound showed to be effective in improving TG, HDL-C, FPI and HOMA-Index, with an optimal tolerability profile in patients with post-menopausal incident metabolic syndrome.
