Detailed Description
This is one randomized, double-blind, placebo-controlled study. The purpose of the present study is to evaluate and/or elucidate the role of the natural supplement, containing chlorogenic acid (10-12%) and luteinyl-7-glucoside (2-4%), on cardio-metabolic risk factors.
The research hypothesis is to evaluate whether natural supplement containing chlorogenic acid and luteolin (Puraltilix, BIONAP SRL, Catania, Italy) may improve several cardio-metabolic parameters in subjects with the metabolic syndrome.
All subjects will be evaluated at baseline and after 6 months of treatment (with natural supplement or placebo).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Dietary Supplement 50 subjects with the metabolic syndrome receiving natural supplement containing chlorogenic acid and luteolin (450 mg/die) |
Dietary Supplement: Natural supplement containing chlorogenic acid and luteolin
50 eligible subjects will receive natural supplement as the oral pills at a fixed dose of 1 pill/day (450 mg/day) for 6 months, as add-on therapy to the ongoing treatment, maintained at fixed doses for the entire study.
|
| Placebo Comparator: Placebo 50 subjects with the metabolic syndrome receiving placebo (without any active ingredients) |
Other: Placebo (without any active ingredients)
50 eligible subjects will receive placebo (without any active ingredients) at a fixed dose of 1 pill/day for 6 months, as add-on therapy to the ongoing treatment, maintained at fixed doses for the entire study.

Outcome Measures
Primary Outcome Measures
- Effect of natural supplement on metabolic parameters including body weight and Body Mass Index (BMI) [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on metabolic parameters, including body weight (kg) and height (m) that will be combined to report BMI in kg/m^2.
- Effect of natural supplement on metabolic parameters including waist circumference [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on metabolic parameters, including waist circumference (cm).
- Effect of natural supplement on metabolic parameters including plasma lipids [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on metabolic parameters, including plasma lipids (total cholesterol, triglycerides, high-density lipoprotein cholesterol HDL-C) (mmol/l), while low-density lipoprotein cholesterol (LDL-C) will be calculated using the Friedewald formula.
- Effect of natural supplement on metabolic parameters including glucose metabolism parameters [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on metabolic parameters, including plasma glycemia (mmol/l).
- Effect of natural supplement on metabolic parameters including plasma insulinemia and HOMA (homeostatic model assessment) index [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on metabolic parameters, including plasma insulinemia (pmol/L) that with glycemia will be combined to report HOMA index.
Secondary Outcome Measures
- Effect of natural supplement on cardio-metabolic parameters including plasma cytokines [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on cardio-metabolic parameters, including plasma cytokines (inflammatory markers and adipokines) (pg/ml), that will be assessed using available enzyme-linked immunosorbent assay (ELISA) kits.
- Effect of natural supplement on cardio-metabolic parameters including plasma lipoproteins [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on cardio-metabolic parameters, including atherogenic lipoproteins as well as the analysis of the full spectrum of lipoprotein subclasses by gel electrophoresis.
- Effect of natural supplement on cardio-metabolic parameters including subclinical atherosclerosis [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on cardio-metabolic parameters, including subclinical atherosclerosis assessed by carotid intima-media thickness (CIMT) (mm).
- Effect of natural supplement on cardio-metabolic parameters including fatty liver index [Change from baseline to 6 months of the supplementation]
Effect of natural supplement containing chlorogenic acid and luteolin on cardio-metabolic parameters, including fatty liver index, a noninvasive method used for steatosis detection and quantification.
