Fish oil is one of the commonly consumed dietary supplements. Fish is rich in Omega-3 fatty acids( PUFA- long chain Poly Unsaturated Fatty Acids), which are very important to health. There are two major Omega-3 fatty acids in Fish oil ; Eicosa Pentaenoic Acid( EPA) and Docose Hexaenoic Acid(DHA).These omega -3 fatty acids are known as Essential Fatty Acids(EFA) ,as these fatty acids cannot be synthesized by the body( or not in the adequate amount) and therefore essential in the diet.
