Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation throughout the body, and have other health benefits.
Fish do not actually produce omega-3 fatty acids, but instead accumulate them by consuming either microalgae or prey fish that have accumulated omega-3 fatty acids, together with a high quantity of antioxidants from microalgae. Fish oil and omega-3 fatty acids have been studied in a wide variety of conditions, such as clinical depression, anxiety, cancer, and macular degeneration, although benefit in these conditions remains to be proven.
For Crohn's and colitis fish oil helps reduce inflammation and thereby helps to minimize symptoms. By aiding in inflammation control, fish oil minimizes the need for anti-inflammatory drugs by treating symptoms through less pharmaceutical pathways.
