METHODS Eighty-three ADHD children (3:1 boys:girls), 8-13 years old, were assigned in a randomized, double-blind, placebo-controlled parallel design to receive 250 mg/d of eicosapentaenoic acid + docosahexaenoic acid provided as phosphatidylserine (300 mg/d PS-Omega3), or fish oil or placebo for 3 months. Stimulant medication or other dietary supplements were prohibited. The measured outcomes were inattention and impulsivity, evaluated by Test of Variables of Attention (TOVA) and blood lipids profile.
