Eicosapentaenoic Acid is used for nutritional deficiencies.

The omega-3 fatty acids eicosapentaenoic acid is long-chain n-3 polyunsaturated fatty acids, which compete with arachidonic acid for inclusion in cyclo-oxygenase and lipoxygenase pathways. It's actions include hypolipidaemic action (especially a reduction in plasma triglycerides) by reducing very-low-density lipoproteins; anti-inflammatory action, attributed to effects on leukotriene synthesis; and antiplatelet effect, attributed to effects on prostanoid synthesis, which promote vasodilatation, reduction in platelet aggregation, increased bleeding time and decreased platelet counts.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
