Researchers at Cedars-Sinai Medical Center's Department of Psychiatry and Behavioral Neurosciences are seeking participants for a clinical trial examining whether two polyunsaturated Omega-3 fatty acids are effective treatments for depression.

The two fatty acids being studied -- docosahexanoic acid (DHA) and eicosapentanoic acid (EPA) -- are found naturally in fish oil, flaxseed and walnuts. Previous studies have indicated that nutritional supplements that contain Omega-3 fatty acids can be an effective treatment for depression, but this is the first to systematically test the two specific fatty acids against each other and against placebo in a large sample of people with major depression. DHA and EPA have anti-inflammatory properties and help stabilize brain cell membranes, both of which play a role in mood regulation.
