Omega-3 fatty acids for autism spectrum disorders (ASD)

James S, Montgomery P, Williams K
Published Online:

It has been suggested that difficulties associated with ASD may be explained in part by lack of omega-3 fatty acids, and that supplementation of these essential fatty acids may lead to improvement of symptoms. The purpose of this review was to assess the evidence for the effectiveness of omega-3 supplementation for core features of ASD and associated symptoms. We found only two small randomised controlled trials that evaluated omega-3 fatty acids for ASD. There is insufficient evidence that omega-3 fatty acids supplementation is an effective treatment for ASD. However, high quality large randomised controlled trials are needed before definite recommendations about this treatment can be made.
