What this trial studies

This study investigates the effects of aronia melanocarpa extract supplementation on cognitive performance and eye health in healthy young adults aged 18-35. It aims to address the negative impacts of online education and workplace stress on concentration and productivity. Participants will undergo a randomized, double-blind, placebo-controlled, cross-over design over a period of six weeks to assess the long-term effects of the supplement on memory and attention. The study also includes a cellulose supplementation as a control.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy men and women aged 18-35 with a BMI between 18-30 kg/m2.

Not a fit: Patients with severe medical conditions or those who smoke may not receive any benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a natural method to enhance cognitive performance and eye health for individuals working or studying online.

How similar studies have performed: Previous studies have shown short-term benefits of anthocyanin supplementation on cognitive performance, but this study explores a novel long-term approach.
