We have included 35 relevant studies: 34 of them involving people compared the effects of n-3PUFAs with those of placebo, and one study involving 40 people compared the effects of n-3PUFAs with those of antidepressants.

All studies were of direct relevance to our review, but we considered the certainty of the evidence to be low to very low. At present, we do not have enough high quality evidence to determine the effects of n-3PUFAs as a treatment for MDD.

We found a small-to-modest positive effect of n-3PUFAs compared to placebo, but the size of this effect is unlikely to be meaningful to people with MDD, and we considered the evidence to be of low or very low certainty, with many differences between studies.

There was also insufficient high quality evidence to determine the effects of n-3PUFAs on negative side effects or numbers not completing studies. We need more evidence, particularly to explain the differences between study findings, e. by looking at individuals who may or may not benefit from n-3PUFAs.

Future studies should also compare n-3PUFAs with usual antidepressant treatment, and investigate the way these treatments may work. At present, we do not have sufficient high-certainty evidence to determine the effects of n-3PUFAs as a treatment for MDD.

Our primary analyses may suggest a small-to-modest, non-clinically beneficial effect of n-3PUFAs on depressive symptomology compared to placebo; however the estimate is imprecise, and we judged the certainty of the evidence on which this result is based to be low to very low. Our data may also suggest similar rates of adverse events and trial non-completion in n-3PUFA and placebo groups, but again our estimates are very imprecise.

Effects of n-3PUFAs compared to antidepressants are very imprecise and uncertain. More complete evidence is required for both the potential positive and negative effects of n-3PUFAs for MDD. Major depressive disorder MDD is highly debilitating, difficult to treat, has a high rate of recurrence, and negatively impacts the individual and society as a whole.

One potential treatment for MDD is n-3 polyunsaturated fatty acids n-3PUFAs , also known as omega-3 oils, naturally found in fatty fish, some other seafood, and some nuts and seeds.

Various lines of evidence suggest a role for n-3PUFAs in MDD, but the evidence is far from conclusive. Reviews and meta-analyses clearly demonstrate heterogeneity between studies. Investigations of heterogeneity suggest different effects of n-3PUFAs, depending on the severity of depressive symptoms, where no effects of n-3PUFAs are found in studies of individuals with mild depressive symptomology, but possible benefit may be suggested in studies of individuals with more severe depressive symptomology.

Hence it is important to establish their effectiveness in treating MDD. This review updates and incorporates an earlier review with the same research objective Appleton To assess the effects of n-3 polyunsaturated fatty acids also known as omega-3 fatty acids versus a comparator e.

placebo, antidepressant treatment, standard care, no treatment, wait-list control for major depressive disorder MDD in adults. We searched the Cochrane Central Register of Controlled trials CENTRAL , Ovid MEDLINE, Embase and PsycINFO together with trial registries and grey literature sources to 9 January We checked reference lists and contacted authors of included studies for additional information when necessary.

We included studies in the review if they: used a randomised controlled trial design; provided n-3PUFAs as an intervention; used a comparator; measured depressive symptomology as an outcome; and were conducted in adults with MDD.

Primary outcomes were depressive symptomology continuous data collected using a validated rating scale and adverse events. Secondary outcomes were depressive symptomology dichotomous data on remission and response , quality of life, and non-completion of studies.

We used standard methodological procedures as expected by Cochrane. We assessed the certainty of the evidence using GRADE criteria. The review includes 35 relevant studies: 34 studies involving a total of participants investigated the impact of n-3PUFA supplementation compared to placebo, and one study involving 40 participants investigated the impact of n-3PUFA supplementation compared to antidepressant treatment.

An SMD of 0. The confidence intervals include both a possible clinically important effect and a possible negligible effect, and there is considerable heterogeneity between studies.

Sensitivity analyses, funnel plot inspection and comparison of our results with those of large well-conducted trials also suggest that this effect estimate may be biased towards a positive finding for n-3PUFAs. AGE-WELL is a contributing partner.

In people with diagnosed depressive disorders, EPA omega-3 fatty acids improve depression symptoms Hallahan B, Ryan T, Hibbeln JR, et al. Review questions In people who have major depressive disorder or bipolar disorder, do omega-3 fatty acids improve symptoms?

Background Depression is a common mood disorder that affects how you feel, think, and behave. How the review was done The researchers did a systematic review , searching for studies published up to July The key features of the trials were: people had a diagnosis of major depressive disorder, bipolar disorder, or a depressive episode where they tried to hurt themselves; or people did not have a diagnosed depressive disorder; and omega-3 fatty acids were compared with placebo.

Outcomes were depression symptoms. What the researchers found DHA omega-3 fatty acids did not improve depression symptoms. Conclusion In people with diagnosed depressive disorders, eicosapentaenoic acid EPA omega-3 fatty acids improve depression symptoms more than placebo.

Omega-3 fatty acids vs placebo in people with or without diagnosed depressive disorders Type of omega-3 fatty acid Diagnosis Number of trials number of people Effect on depression symptoms Docosahexaenoic acid DHA With or without depressive disorder 12 trials people No difference in effect Eicosapentaenoic acid EPA With or without depressive disorder 26 trials people EPA improved symptom scores more than placebo Eicosapentaenoic acid EPA Depressive disorder 19 trials people EPA improved symptom scores more than placebo Eicosapentaenoic acid EPA No depressive disorder 7 trials people No difference in effect.

Depression is a common mood disorder that can make it hard to cope with everyday life.

Causes and risk factors for depression include genes, difficult experiences and life circumstances, chronic anxiety disorders, biochemical changes, medical problems, and lack of light.

Psychological therapies e. This patient decision aid helps adults diagnosed as being depressed decide on the type of medicine by comparing the benefits, risks and side effects of each antidepressant.

For some time we have known that omega-3 PUFA can induce anti-depressant and anti-inflammatory effects but, without further understanding of how this happens in the human brain, it has been difficult to develop treatments. Our study has helped shine a light on the molecular mechanisms involved in this relationship which can inform the development of potential new treatments for depression using omega-3 PUFA. Previous research has shown that people with major depressive disorder have higher levels of inflammation in their bodies than those without the disorder. There are currently no proven anti-inflammatory treatment strategies for depression and, although two important omega-3 PUFAs, EPA and DHA, have been shown to provide anti-inflammatory and antidepressant effects, the precise mechanism by which they do this is unknown.
