Abstract:

Objective: This study tested whether soy-derived phosphatidylserine (PS) could improve ADHD symptoms in children aged 4-14 who had not received ADHD medication before.



Methods: Thirty-six children were randomly given either 200 mg of PS daily or a placebo for two months. The main tests measured ADHD symptoms, short-term memory, and attention to visual stimuli.



Results: PS significantly improved ADHD symptoms, short-term auditory memory, and attention issues like inattention and impulsivity. The PS group showed clear improvements in these areas, while the placebo group had no significant changes. PS was well-tolerated, with no side effects reported during the study.
