The effect of alpha-linolenic acid supplementation on ADHD symptoms in children: a randomized controlled double-blind study.

Background: Attention deficit-hyperactivity disorder (ADHD) is the most common neuro-developmental disorder in childhood.

Previous studies of supplementation with fish oil or long-chain omega-3 fatty acids to children with ADHD yielded mixed results.
