Inflammation is a vital self-defense mechanism and essentially balanced by anti-inflammatory agents in the body for better organ health. Omega-3 fatty acids play a role of anti-inflammatory agents to maintain balance. There are two types of important Omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA).
