In a randomized, double-blind, placebo-controlled trial, 50 participants with major depressive disorders were allocated to take 1000 mg of omega-3 fatty acids or placebo daily for 12 weeks.
There was a statistically significantly greater improvement in both measures of depression, insomnia, and anxiety, in the omega-3 group as compared with the placebo group.
