Topic: fish oil side effects

There are many types of fish that contain fish oil. Fish oil contains two important omega-3 fatty acids called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).    

Fish oil is believed to have health benefits because it contains omega-3 fatty acids. Fish rich in omega-3 fatty acids include mackerel, herring, tuna, and salmon. The body does not produce many of these oils on its own. Omega-3 fatty acids reduce inflammation, swelling, and blood clotting.
