Fish & Depression

Many people who suffer from depression do not want to take medications. Some people claim that medications make them feel worse, while others simply would like to find a more natural approach to treating their symptoms. While research is only minimal at this point, there is a chance that consuming fish oil can help treat depression.

  1. Research

    • Some research has shown that consuming fish oil helps reduce depression and the mood swings which are associated with bipolar disorder. A study which was done by Andrew Stoll, M.D. showed that 64 percent of manic-depressive participants who took 10 grams of fish oil every day for four months saw a reduction in their symptoms. That being said, more research needs to be done on fish oil as a treatment option for depression.

    Theories/Speculation

    • The omega-3 fatty acids found in fish oil are believed to be the reason it may work as an effective treatment options for depression. A study which was published in the Journal of Affective Disorders showed that levels of omega-3 fatty acids in red blood cell membranes were lower among patients with depression. It is thought that omega-3 is necessary for proper brain function and increases serotonin levels. Some believe that the reduction of foods high in omega-3 in our society is the reason for increased levels of depression.

    Types

    • It is recommended for individuals to take fish oil supplements instead of eating fish. Over-consumption of fish can be dangerous due to mercury contamination levels. That said, there is a possibility that fish oil supplements may be affected by mercury as well, so it is important to read labels for products which do not contain any. It is recommended to begin taking fish oil at a lower dosage and working up to a higher dosage over time.

    Considerations

    • At this point, only minimal research has been done on fish oil as a treatment option for depression. Most medical experts do not currently recommend that patients use fish oil in place of their antidepressant medication, despite some research that shows it may be just as effective. It is most ideal for patients to consume fish oil in addition to their antidepressant medication to see the best results. Patients are recommended to talk to their doctors before beginning a fish oil supplement.

    Alternative Options

    • Note that there are many other good sources of omega-3 fatty acids aside from fish oil. Eggs, flaxseed, pumpkin seeds, canola oil, red meat, soybeans and walnuts are all other good sources of omega-3. Individuals who do not eat fish or do not feel comfortable taking fish oil supplements may be able to take advantage of the depression-reducing benefits of omega-3 fatty acids by incorporating these foods into their diet.
