Omega-3 Fatty Acids in the Treatment of Bipolar Disorder: A Double-Blind, Placebo-Controlled Trial
United States240 participantsStarted 1999-10
Plain-language summary
This study will examine the effectiveness of omega-3 fatty acids, compounds found in plants and fish, in treating bipolar disorder.
Some studies have indicated that omega-3 fatty acids may be effective in treating mood disorders.
For example, one investigator has shown a correlation between the prevalence of major depression and the amount of fish consumed per capita worldwide. Others have found decreased amounts of EPA (one of the active ingredients in omega-3 fatty acids) in the red blood cells of patients with major depression. And a recent small study of patients with bipolar illness indicated that omega-3 fatty acids prevented relapses, especially of depression, in patients.
Patients with bipolar disorder who are not benefiting satisfactorily on their current medications are eligible to participate in this study. Candidates will be screened with a psychiatric evaluation, routine blood tests, a urine test and other tests needed to monitor medications. Participants will be randomly assigned to one of two groups: one group will receive 6 grams of omega-3 fatty acid every day for 16 weeks; the second will receive a placebo (inactive capsule). In addition, patients in both groups will continue to take their previous medications. Every 2 weeks, all patients will have their vital signs checked and be evaluated for side effects and mood changes. At the end of the 16-week study period, all patients will be given the opportunity to continue in the study for another 8 months and receive active drug (omega-3 fatty acid). Patients who continue will be evaluated once a month and will have blood drawn on the last visit for routine tests.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
