Advanced Strategy of Food Supplements for the Optimization of Satiety and Lipid Metabolism in Maturity
The SACIANS study (Advanced Strategy of Food Supplements for the Optimization of Satiety and Lipid Metabolism in Middle-Aged Adults) aims to evaluate the combined effect of commercially available food supplements on satiety and lipid metabolism in adults over 45 years of age who are overweight.
This 12-week randomized controlled clinical trial will include 80 participants divided into two parallel groups: a control group without supplementation and an experimental group receiving a specific combination of food supplements with proven nutritional safety and previous evidence of functional effects on metabolism.
Primary outcomes include changes in biochemical parameters related to lipid metabolism (cholesterol profile, triglycerides, and glucose), as well as markers of oxidative stress and inflammation. Secondary outcomes include variations in body composition, perceived satiety, emotional well-being, sleep quality, and lifestyle habits such as diet adherence and physical activity.
The study will be conducted at the University of Alicante and the EIEH Clinic (Elche Institute of Exercise and Health), following the principles of the Declaration of Helsinki. The goal is to provide scientific evidence on the synergistic potential of existing food supplement combinations to promote metabolic balance and healthy aging.
Overweight and metabolic alterations in adults over 45 years old represent a growing public health concern, frequently associated with conditions such as type 2 diabetes, dyslipidemia, and cardiovascular disease. Although numerous food supplements are currently available on the market with reported effects on satiety or lipid oxidation, most lack personalization and evidence regarding their combined effects.
The SACIANS project (Advanced Strategy of Food Supplements for the Optimization of Satiety and Lipid Metabolism in Middle-Aged Adults) is a 12-week, randomized, controlled, parallel-group clinical trial designed to evaluate the efficacy of different combinations of commercially available food supplements on metabolic and emotional parameters in adults with overweight or mild obesity.
Participants (n = 80; 40 per group) will be randomly assigned to one of two arms:
Control group: No supplementation.
Experimental group: Daily intake of a combination of registered food supplements selected based on their nutritional profile, labeling, safety, and prior evidence of functional efficacy.
Assessments will include biochemical parameters (glucose, lipid profile, oxidative and inflammatory biomarkers), body composition (via bioimpedance and 3D scanning), blood pressure, and psychological well-being (stress, anxiety, and sleep quality). Lifestyle factors such as Mediterranean diet adherence and physical activity (recorded with Fitbit) will also be monitored.
The trial will follow the ethical standards of the Declaration of Helsinki and has been approved by the Ethics Committee of the University of Alicante (approval date: May 29, 2025). Statistical analyses will be performed using SPSS v24.0, applying repeated-measures ANOVA and appropriate post hoc corrections.
This study aims to identify potential synergistic effects among existing food supplement formulations, contributing to the rational and evidence-based use of these products for improving satiety, lipid metabolism, and metabolic health in adults.
