Omega-3 Fatty Acids for Bipolar Disorder

Topic Overview

Omega-3 fatty acids are found in marine or plant sources, such as fish oil and flaxseed oil. A few studies suggest that adding omega-3 fatty acids to medicine (such as lithium) can help reduce the depressive symptoms of bipolar disorder in some people. Omega-3 fatty acids don't seem to have any effect on the manic symptoms of bipolar disorder. And omega-3 fatty acids alone are not a good treatment for bipolar disorder. They are not a replacement for medicine or other therapy used to treat bipolar disorder.footnote 1, footnote 2

There are few, if any, negative side effects of taking omega-3 fatty acids. Loose stools were reported most often. Researchers think that omega-3 fatty acids help support the membranes of brain cells, making it easier for them to send signals to one another, which may reduce the likelihood of depressive symptoms.footnote 1
