Research: Omega-3 Fatty Acids in ADHD and Related Neurodevelopmental Disorders

Authored by Richardson, AJ in Int Rev Psychiatry., Volume 18, Issue 2, p. 155-172, (2006).

Article summary (posted Nov 14, 2006):

This article reviews the research on the involvement of omega-3 essential fatty acids (EFAs) in ADHD and several others disorders of brain development. The author concludes that it may be possible to improve these conditions with omega-3 supplementation.

The author describes the symptoms of ADHD (inattention and/or hyperactivity impulsivity) and the links between ADHD and dyslexia, antisocial behavior, developmental coordination disorder, mood disorders, and schizophrenia. The author suggests that these disorders may be the result of a lack of omega-3 in the diet. She describes research showing that omega-3 supplementation can improve the symptoms of these disorders. It is not known; however, what dose of omega-3 supplement is most effective. Most studies used 300-700 mg of the two omega-3 EFAs (EPA and DHA). This level of omega-3 should be safe, but may not be high enough to treat some disorders.
