However, whether and Vitamins for eye health EPA and DHA initiate their effects on depression differentially or synergistically Omdga- regard to dosage and proportion are still unclear. Therefore, we conducted this meta-analysis to provide an jood on the therapeutic effect of omega-3 PUFAs and on the associations between EPA or DHA mooc and depression, tor the effects of the dosage and proportion of EPA or Disoders supplementation on depression.
We applied our search in the following databases, from inception to 20 December PubMed mood the Ovid version of Metabolism Boosting Protein Supplementary 1. We also searched the references of selected studies and earlier meta-analyses to disordfrs Omega- for mood disorders potential studies for inclusion in our analysis.
Discrepancies between reviewers were resolved by disordes in all cases and if necessary, by arbitration by a third reviewer. We excluded studies with the following characteristics: 1 depression disirders to other neuropsychiatric mood and Post-race recovery foods perinatal gor depressive disorder.

Our primary analysis used the following hierarchy of psychometric instruments: 1 moodd Hamilton Rating Scale for Depression HRSD2 the Montgomery-Asberg Depression Rating Scale MADRS ror, 3 the Beck Depression Moo Post-race recovery foodsand 4 the primary outcome of didorders selected study.
We divided the omega-3 PUFAs into 4 categories: DHA-pure, DHA-major, EPA-pure, and EPA-major. The DHA- kood EPA-pure Post-race recovery foods were those in which the omega-3 PUFA supplementation contained only DHA or EPA, respectively. We used standardized mean differences as the summary statistic O,ega- continuous data by attaining the mean SD and sample size n of the omega-3 PUFAs and risorders groups.
When SDs were not available, we estimated them based on the other statistical parameters reported in the study or requested by authors.
All data were analyzed at a single point at the end of the trial. Given the expected heterogeneity, we a priori used a random-effects model.
A sensitivity analysis was performed by excluding low-quality studies, trials recruiting participants with particular conditions, or trials with characteristics that were different from those in the other trials.
All statistical analyses were performed using RevMan 5. An outline of the search strategy is presented in Supplementary 1. From the searches for recently published RCTs in the databases, records were identified. Of these, records were reviewed, and 16 trials met the eligibility criteria. From the searches for systematic reviews or meta-analyses, 25 potential records were identified, and 12 RCTs met the eligibility criteria.
Two studies describing results that came from the same trial were removed 14 Ultimately, 26 trials were included in our meta-analysis Fig. Among these trials, 12 showed a significant effect of omega-3 PUFAs on the selected rating scales.
The risk of bias for all included trials was assessed by the Cochrane methods, and the results can be seen in supplementary 2. Flow chart of literature search and study selection. This figure described the route of studies inclusion. Among researches from database and other studies, there are 26 trials were satisfied for the criteria of our study.

Our funnel plot and statistical test showed no evidence of publication bias Fig. Funnel plot of effect sizes for clinical trials included in the meta-analysis. This funnel plot depicts the standardized mean difference of trials versus their standard error.
Published trials are depicted as dark circles. This effect was in line with those of previous studies 2912 and may be mediated by the known mechanism of omega-3 PUFAs at the cellular level In general, omega-3 PUFAs are the essential fatty acids used to produce EPA; from EPA, they then synthesize DHA.
However, whether DHA, EPA or both actually contribute to improvements in depression is a topic of considerable debate in current studies. Hence, the subgroup analysis in our meta-analysis demonstrated that only both EPA-pure and EPA-major treatments had favorable effectiveness in depression improvement.
This finding was consistent with that of a review by Song et al. However, that study also included participants with a secondary diagnosis of depression.
These results might be related to differences in the metabolism of EPA and DHA. To the best of our knowledge, although EPA is more efficacious with regard to its antidepressant effect, the relationship between EPA and DHA in depression therapy remains unclear.
We cannot determine whether the efficacy occurs because of EPA alone or because of an interaction with DHA supplementation. Some possible mechanisms are demonstrated below. In contrast to DHA, EPA is not highly concentrated in the human brain at steady state.
EPA can rapidly enter the brain as a free fatty acid and is not re-acylated into phospholipid membrane stores because it is quickly metabolized and beta-oxidized to act as an effector Based on this process, in the last decade, the contribution of inflammation to depression has been extensively documented 4041and both DHA and EPA or EPA alone may reduce the occurrence of inflammation eicosanoids.
In the first mechanism, DHA and EPA can lead to decrease in production of proinflammatory cytokines, such as tumor necrosis factor TNF -α 42interleukin IL -1β, IL-2, and IL-6, which are determined by eicosanoid discharge and related to depression.
Furthermore, both DHA and EPA can reduce inflammation through their precursor arachidonic acid. DHA and EPA combine with arachidonic acid for amalgamation into membrane-based phospholipids, leading to a decline in both cellular and plasma concentrations of arachidonic acid.
The other possibility is that EPA, but not DHA, can decrease the production of arachidonic acid by inhibiting deltadesaturase activity. In the cyclooxygenase enzyme system, EPA may compete with arachidonic acid for phospholipase A 2 PLA 2 and help block the process of proinflammatory eicosanoid synthesis from arachidonic acid e.
In addition, one study determined that individuals with elevated interferon IFN -α levels that resulted from chronic hepatitis C always meet operational diagnostic criteria for depression 43and a recent RCT pointed out that EPA but not DHA ameliorated IFN-α-induced depression Overall, although we cannot ignore the contribution of DHA to the depression-related metabolic pathway, the unique antidepressant effects of EPA make it more appealing.
In addition to the anti-inflammatory effect, other mechanisms can explain the advantages of EPA supplementation. First, EPA supplementation has been associated with N -acetyl-aspartate increases in the brain, a marker for neuronal homeostasis, suggesting its role as a neuroprotective agent EPA supplementation also increased the ratio of cerebral phosphomonoesters to phosphodiesters, an indicator of phospholipid turnover, and reversed brain atrophy in a subject with major depressive disorder Second, EPA is the natural ligand for the peroxisome proliferator-activated receptor gamma PPARγ nuclear transcription receptor that downregulates the expression of nuclear factor-kappa B Nf-kB and inhibits the neuronal parainflammatory cascades implicated in the pathophysiology of depression Low concentrations of EPA could bind with very high affinity to all PPARs, whereas DHA binding is too low to be measured, and DHA may provide tonic inhibition of PPARs at high concentrations 484950 Third, in the rodent olfactory bulbectomy depression model, EPA treatment normalized depressive behaviors by attenuating prostaglandin E 2 -mediated activation of IL-6, decreasing mRNA expression for corticotrophin-releasing hormone CRH and inhibiting hyperactivation of the hypothalamic-pituitary-adrenal HPA axis EPA may also exert a greater neurotrophic effect than DHA, as EPA supplementation has been shown to increase brain-derived neurotrophic factor BDNF levels after traumatic brain injury 53 Based on the significant proportion of EPA supplementation in our results, we also conducted a subgroup analysis to examine the antidepressant effect of its dosage.
Depending on the significant difference between EPA dosage groups, our included studies may confirm that the efficacy of EPA is dose dependent.
Two assumptions can probably provide explanations. This finding might suggest a difference in the handling of these two PUFAs during the passage from blood across the blood-brain barrier BBB to the central nervous system CNS and also serves as a reminder that low doses of dietary EPA intake may be sufficient to have therapeutic effects on depression.
Second, a study demonstrated that EPA at high dosages may hamper the activity of CYP2D6 and CYP2A4, which are considered major enzymes in the metabolism of antidepressant drugs selective serotonin reuptake inhibitors, SSRIs.
Depended on the efficacy of EPA concentration and dosage, we still cannot neglect the applicable population for this treatment. However, the number of studies and subjects were small, and confidence interval was wide.
It may be insufficient to support the efficacy of EPA augmentation.

What the research says about omega-3s and depression. This can lead to improvements in both physical and mental health.
Including fish in your diet several times per week is one way to get valuable omega-3 fatty acids. Another way is to try a fish oil supplement containing DHA and EPA.
Bipolar disorder is a complex mental health condition that features extreme changes in mood. According to the National Institute of Mental Health NIMH , bipolar disorder affects around 4.
There are genetic, biological, and environmental factors that impact the way your brain regulates mood. The combined approach of medication and therapy is often successful. Including omega-3 supplements as part of your treatment might also help. Results are mixed, though. But it was safe, well-tolerated, and rated higher by mental health professionals for improving global symptoms.
Omega-3 fatty acids like docosahexaenoic DHA and eicosapentaenoic acids EPA originate in phytoplankton. The fish that feed on phytoplankton provide dietary or supplemental sources of these fatty acids.
DHA and EPA affect the brain in several different ways. A review of 17 clinical studies found low levels of omega-3 fatty acids in symptomatic bipolar disorder. The review also found that omega-3 fatty acid supplementation was successful in treating depression or mania in five out of five trials.
Omega-3 fatty acids may also play a part in neurotransmission receptor function. A study involving rats found that fish oil supplements impacted hippocampal receptors and had an antidepressant-like effect.
Omega-3 fatty acids also help new neurons form by changing cell membrane fluidity so that serotonin can work more effectively. Serotonin is a neurotransmitter that can stimulate the growth of new neurons.
Omega-3 fatty acids play an important role in the development, functioning, and even aging of the human brain. A deficiency increases the chance of various mental health conditions such as:. Insufficient omega-3 fatty acids can also contribute to neurodevelopmental differences such as attention deficit hyperactivity disorder ADHD and autism spectrum disorder ASD.
The best source of omega-3 fatty acids is fish. Unlike a fish oil supplement, fish contains other beneficial ingredients such as protein and vitamins. It can take weeks before you notice the benefits of fish oil supplementation. If you take fish oil with a meal containing fat, this can increase the effectiveness and bioavailability of the omega-3 fatty acids.
Fish oil may slow blood clotting. Consider consulting with a healthcare or mental health professional before taking fish oil supplements if you take anticoagulant medication, or if you have an upcoming surgery.
Research shows an elevated chance with higher omega-3 blood levels, but a reduced chance with frequent dietary consumption of seafood, and no link with dietary omega-3 intake.
Fish oil contains omega-3 fatty acids, which can help your brain in several ways. Low levels of omega-3 fatty acids are associated with certain mental health conditions. Fish oil can decrease inflammation, which researchers believe may be a key part of bipolar disorder.
Adding fish to your diet is one way to increase your omega-3 fatty acid intake. Psych Central has a bipolar disorder resource hub you can visit for more information about managing bipolar disorder. See which vitamins are often used to help manage symptoms of bipolar disorder and the research behind them.
There are many treatments for bipolar disorder, including medications, therapy, and self-help strategies. Here's how to know which one you need. When typical treatments don't help your symptoms, it may be time to explore options for treatment resistant bipolar disorder. Many people experience shifts in mood from time to time.
