Lin PY and Su KP.
J Clin Psychiatry. 2007;68:1056-61.
This meta-analysis systematically evaluated the therapeutic benefit of omega-3 polyunsaturated fatty acids (PUFAs) using data from 10 double-blind, placebo-controlled studies in patients with mood disorders receiving omega-3 PUFAs for ≥4 weeks. Omega-3 PUFAs showed significant antidepressant efficacy, with significant improvement of depression in patients with clearly defined depression or with bipolar disorder.

Nemets H et al.
Am J Psychiatry. 2006;163:1098-100.
The efficacy of omega-3 fatty acids were examined in 28 children (aged 6-12 years) with major depressive disorder, who received omega-3 fatty acids or placebo as pharmacological monotherapy, for 16 weeks.
