....Epidemiologic evidence relates increased fish consumption to a decreased incidence of depression, but no clinical trials have been done with fish consumption. Further, tests of a limited number of over-the-counter fish oil supplements have revealed negligible contents of mercury and organochlorines, including polychlorinated biphenyls, whereas these compounds are a concern with fish intake.
In summary there is not sufficient evidence to suggest the use of fish oils for the treatment of depression and no evidence for the prevention of depression. Nonetheless, fish oils are good for the heart, have no demonstrated adverse effects when taken in reasonable dosages, and could potentially be beneficial for mood. Although patients should be discouraged from taking fish oils as a substitute for antidepressants or mood stabilizers, if they wish to take fish oils as an adjunct to those treatments, they should be aware of the tentative nature of the evidence for a beneficial effect on mood and inform themselves about possible contaminants.
