Our double-blind, placebo-controlled, parallel-group, dose-escalation, clinical trial aimed to test the effect of a combined nutraceutical containing bergamot extract (120-mg flavonoids), phytosterols, vitamin C, and chlorogenic acid from dry artichoke extract on 90 overweight dyslipidemic subjects. Participants were randomly allocated to treatment with two pills of either active treatment or placebo, or a combination of both (a pill per treatment). After 8 weeks, all active-treated groups experienced a significant improvement in triglycerides (TG) versus placebo and in low-density lipoprotein cholesterol (LDL-C) versus baseline and placebo treatments. In the high-dose-treated group, also total cholesterol (TC), nonhigh-density lipoprotein cholesterol (non-HDL-C), γ-glutamil transpeptidasi, high-sensitivity C-reactive protein (hs-CRP), and tumor necrosis factor-α (TNF-α) significantly decreased. At 24-week follow-up, TG levels maintained lower than baseline in all groups. All patients allocated to either low-dose or high-dose active treatment experienced a significant decrease in TG, LDL-C, and homeostatin model assessment of insulin resistance. In subjects taking high-dose active treatment, adiponectin significantly increased, whereas TC, non-HDL-C, insulin (fasting plasma insulin), leptin, leptin/adiponectin ratio, hs-CRP, and TNF-αwere significantly reduced. The tested nutraceutical showed to improve lipid and glucose metabolism, adipokines pattern, and systemic inflammation in dyslipidemic overweight subjects.
