While limited evidence suggests that omega-3 supplementation may reduce antisocial behavior in children, studies have not reported on post-treatment follow-up and most treatment periods have been of short duration. This study tests the hypothesis that omega-3 supplementation over six months will reduce behavior problems in children both at the end of treatment and at six months post-treatment.

In this randomized, double-blind, placebo-controlled, stratified, parallel-group trial, a community sample of 8–16 year old children were randomized into a treatment group (N = 100) and a placebo-control group (N = 100). The supplementation consisted of a fruit drink containing 1 g/day of omega-3 or a placebo consisting of the same fruit drink without omega-3.
