Scientific titleClinical evaluation of the efficacy of a food supplement on body weight and perceived food craving: a randomized, double-blind, parallel-group, placebo-controlled study
Study objectives The primary objective is to evaluate the efficacy of the product in body weight reduction, assessed through body weight measurement and calculation of Body Mass Index (BMI).
The secondary objective is to evaluate additional effects on body composition parameters (waist and hip circumference, fat mass). Additionally, the study will evaluate participants’ self-perceived changes in food craving control, appetite-related sensations, body perception, overall well-being, and product acceptability through a self-assessment questionnaire.
Ethics approval(s)

Approved 07/04/2026, International Ethics and Integrity Committee (Via Per Garbagnate 61, Lainate (Milano), Milano, 20045, Italy; +39 3783037302; secretariat@ieicommittee.com), ref: IC0019 A

Health condition(s) or problem(s) studiedExcessive food cravings
InterventionThe investigational product is SelectSIEVE®LIBRA, containing 60% Salvia officinalis extract and 40% Morus alba (white mulberry) extract, with maltodextrin and magnesium stearate as excipients.
The placebo contains maltodextrin and magnesium stearate only.
Half of the recruited subjects are randomized to receive the active product, while the other half receive the placebo. A restricted randomization list is generated by an independent technician using the appropriate algorithm (Wey’s urn) implemented in PASS 11 software (PASS, LLC, Kaysville, UT, USA) and stored in a secure location. The principal investigator or a designated delegate dispenses the investigational products according to the randomization list.
The study is conducted as a double-blind trial: subjects, investigators, and collaborators are blinded to product allocation. Both the active and placebo products are provided in identical packaging, with no distinguishable differences between them.
The study is structured into two phases: a one-month screening period prior to product intake, followed by 84 days of treatment. Clinical visits are scheduled at T−28 (initial visit), T0 (baseline visit), and follow-up visits at T14, T28, T56, and T84 (final visit).
Subjects take the assigned treatment for 84 ± 2 days as follows: 2 capsule per day, half an hour before dinner, with a glass of water.
Intervention typeSupplement
Primary outcome measure(s)
  1. Body weight (Kg) measured using a scale at T0, T14, T28, T56, T84
  2. Body Mass Index (BMI) (kg/m²) measured using weight (kg) / height² (m²) at T0, T14, T28, T56, T84
Key secondary outcome measure(s)
  1. Waist circumference (cm) measured using a tape at T0, T14, T28, T56, T84
  2. Hip circumference (cm) measured using a tape at T0, T14, T28, T56, T84
  3. Fat Mass (FM) (kg) measured using the BIA 101 ASE device (Bioelectrical Impedance Analysis) at T0, T14, T28, T56, T84
  4. Self-evaluation questionnaire measured using 17 multiple-choice questions assessing perceived efficacy and product pleasantness at T14, T28, T56, T84
Completion date04/09/2026
