Cognitive Performance and Mood After Ingestion of Dietary Supplement by University Students

Portugal75 participantsStarted 2025-01-02

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
