Fish oils are a good source of EPA and DHA

Fish oils are a natural source of the omega 3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic (DHA).

What are omega 3 fatty acids? These are polyunsaturated fatty acids your body needs for the proper support and function of every cell in your brain and nervous system. Your body can’t make omega 3’s, so you need to get them from your diet.

Research confirms that EPA and DHA can lower your risk for heart disease and ease symptoms of depression and other mood-related conditions.

Studies also show they suppress inflammation which relieves symptoms of arthritis, inflammatory bowel disease and asthma symptoms.
