Omega-3 fish oil supplements can reverse chronic debilitating depression, and they are as effective as a powerful antidepressant drug, a major new study has discovered. The OM3 Emotional Balance fish oil supplement helped a group of 432 patients with major unipolar depression that could not be helped by conventional treatment, and did not respond to antidepressants. The group was given the supplement for eight weeks and at doses of 1050mg of EPA and 150mg of DHA every day. Nobody in the group was suffering from anxiety, and so researchers are not sure if the supplement could help people who have depression with anxiety. The study, carried out by researchers from the University of Montreal, underlines earlier research that has suggested people who are deficient in polyunsaturated fatty acids - found in fish oils - are more likely to suffer from depression.
