Objective: This study aimed to test, for healthy teenage males, whether Cognizin® citicoline, affected attention, reaction times, and their quickness in completing tasks—simple and complex.

Methods: In this study, 75 healthy teenage males took either 250 mg or 500 mg of citicoline, or a placebo, every day for 28 days. They did tests to check how well they focused and how fast they could respond or finish tasks.

Results: Those who took citicoline focused better and completed tasks faster than those who took the placebo. Higher doses (500 > 250 > Placebo) also helped them stay more focused and less impulsive (acting without thinking).
