Effects of Natural Supplement Containing Chlorogenic Acid and Luteolin on Cardio-metabolic Risk Factors
- Conditions
- Metabolic Syndrome
- Interventions
- Other: Placebo (without any active ingredients)Dietary Supplement: Natural supplement containing chlorogenic acid and luteolin
- Registration Number
- NCT03444558
- Lead Sponsor
- University of Palermo
- Brief Summary
Clinical trial about beneficial effects of natural ingredient containing chlorogenic acid and luteolin on liver health and conditions related to liver (such as metabolic syndrome) for general body health.
- 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).

- Primary Outcome Measures
Name Time Method 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 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 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
Name Time Method 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 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.
