Abstract

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‐α were significantly reduced. The tested nutraceutical showed to improve lipid and glucose metabolism, adipokines pattern, and systemic inflammation in dyslipidemic overweight subjects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
