This study aims to determine if marine monounsaturated and polyunsaturated fatty acids can benefit children aged 6-16 years with ADHD and related symptoms. It is a randomized, double-blind, placebo-controlled study involving approximately 330 children from Norway. The study will assess ADHD symptoms reported by caregivers, teachers, and the child at baseline, after 6 months of treatment, and 6 months post-treatment. Secondary outcomes will include reading and writing difficulties, cognitive functions, and physical health.
