Eicosapentaenoic acid (EPA) is a long-chain omega-3 fatty acid from fatty fish and fish oil. Your body uses it to build cell membranes and to make eicosanoids, signaling molecules that affect inflammatory processes.
Many people take EPA for heart health. It helps keep triglyceride and blood pressure levels in the normal range. Others reach for it to ease stiff, achy joints or as one piece of a broader plan for stable mood and emotional wellness.
Take EPA as a softgel or liquid. Pair it with a meal that contains some fat to boost absorption. A daily dose fits easily into most routines.
EPA can thin the blood. High doses may extend bleeding time. Talk to your doctor before use if you take blood thinners like warfarin or aspirin, or if you have a surgery coming up. Anyone with a fish or shellfish allergy should read product labels closely.
