  • Fish oil provides the body with omega-3 fatty acids, which are essential for good health. Evidence on the benefits of fish oil show that it is, or has the potential to be, effective in treating certain diseases.

    Heart disease

    The strongest evidence of fish oil's benefits involves its ability to prevent heart disease. Fish oil can lower blood pressure, reduce blood triglyceride levels, and prevent heart attack and other forms of heart disease, according to research compiled by the Mayo Clinic. A UCLA study shows fish oil supplements decreased resting heart rate and improved circulatory function in healthy subjects.

    Rheumatoid arthritis

    The anti-inflammatory qualities of fish oil help it treat early stage rheumatoid arthritis.

    Cancer

    Fish oils also show promise in treating and preventing cancer, including colon cancer. The Beth Israel Deaconess Medical Center at Harvard University reports that fish oil supplements help some cancer patients avoid the weight loss that accompanies treatment.

    Mental health

    Doctors at the Mayo Clinic and the Beth Israel Deaconess Medical Center at Harvard University note that while more research is needed, fish oils show promise in treating depression and bipolar disorder.

    Types

    Fish oil can be taken in supplement form, but it is readily available in foods, including many grains and fruits and vegetables. Its richest source, according to doctors at the Beth Israel Deaconess Medical Center, is cold-water fish.
