This study investigates the effect of dietary supplementation on cognitive Performance and mood in university students over a 60-day period using a double-blind randomized controlled design. This study includes 75 participants, aged 18 or older. Participants will be randomly assigned to group I (n=25; will receive the supplement one), group II (n=25; will receive the supplement two), and group III (n=25; control/placebo).
Assessments will be conducted before starting supplementation, 30 days after, and at the end of the intervention to determine the effect of the supplementation on cognitive performance and mood. The main outcomes include cognitive status and mood measured by Depression Anxiety Stress Scales - (DASS), Brief Symptom Inventory (BSI) and Self-efficacy scale in higher education. Adherence to supplementation and potential side effects will also be assessed.
Based on the data obtained at these three assessment points, it will be possible to qualitatively address the actual effect of supplements on students' cognitive performance.
In addition, the participants nutritional status will also be assessed using the Simplified Appetite Nutrition Questionnaire (SANQ) and their perception of it using the Visual Appetite Scale (VAS). Both measurements will take place before the start of supplementation and at the end of the intervention.
