A pilot study in Israel found during a clinical research that treatment with omega-3 fatty acids might treat children with clinical depression. Dr. R. H. Belmaker, of Ben Gurion University of the Negev, and colleagues have conducted the research that is first of its kind. During the research, twenty-eight depressed children of the age group 6 to 12 years were aimlessly given omega-3 fatty acids or placebo. The omega-3 fatty acid supplement that used in the research was a combination of eicosapentaenoic acid and docosahexaenoic acid. Seventy percent of the children in the main treatment group showed decreasing depression.The placebo group had showed no reduction. Four children in the omega-3 group achieved reduction in depression. The American Journal of Psychiatry has published the research. During the experimentation, the children have showed no side effects as well.
