About this study

Official title: Effects of the Natural Supplement CitraVes Containing Nanovesicles Delivered From Citrus Limon (L.) Juice on Cardio-metabolic Risk Factors in Subjects With Metabolic Syndrome

Clinical trial about beneficial effects of natural supplement in a spray-dried formulation, citraVes™, obtained from Citrus Limon (L.) juice on general body health.

Read the detailed description

This is one randomized, double-blind, placebo-controlled study. The aim of the present study is to investigate the role of a natural product, citraVes™ on several cardiovascular risk factors.

The research hypothesis is to evaluate whether this natural supplement containing nanovesicles delivered from Citrus Limon (L.) juice (Navhetec S.R.L., Palermo, Italy) may improve different cardio-metabolic parameters in subjects with the metabolic syndrome. All subjects will be evaluated at baseline, after 1 month and after 3 and 6 months of supplementation with natural product or placebo.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Natural supplement containing nanovesicles delivered from Citrus Limon (L.) juice_MetSDietary supplement

    20 eligible subjects with the metabolic syndrome (MetS) will take natural supplement containing a spray-dried formulation of citraVes™, directly in the mouth, without water, to be dissolved preferably under the tongue, at a stable dose of one sachet a day (1000 mg/day) for 6 months and as add-on therapy to the ongoing treatment, maintained at fixed doses for the entire study.

  • Placebo (without any active ingredients)Dietary supplement

    20 eligible subjects with the metabolic syndrome will take placebo in a spray-dried formulation (without any active ingredients) directly in the mouth, without water, to be dissolved preferably under the tongue, at a stable dose of one sachet a day for 6 months, as add-on therapy to the ongoing treatment, maintained at fixed doses for the entire study.

  • Natural supplement containing nanovesicles delivered from Citrus Limon (L.) juice_HSDietary supplement

    20 eligible healthy subjects (HS) will take natural supplement containing a spray-dried formulation of citraVes™, directly in the mouth, without water, to be dissolved preferably under the tongue, at a stable dose of one sachet a day (1000 mg/day) for 6 months, maintained at fixed doses for the entire study.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Baseline in Plasma Lipids in Healthy Subjects (time frame: 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
