eikozapentaensyra

Eikozapentaensyra, known in English as eicosapentaenoic acid (EPA), is an omega-3 fatty acid with 20 carbon atoms and five cis double bonds (20:5 n-3). It is a long-chain polyunsaturated fatty acid that is a key component of cell membranes and a precursor to anti-inflammatory eicosanoids. Humans can obtain EPA from the diet, and while the body can convert some alpha-linolenic acid to EPA, the process is inefficient, so direct intake is common.

EPA occurs mainly in fatty fish and marine oils, such as fish oil, krill oil, and certain algal sources. It is usually consumed together with another omega-3 fatty acid, docosahexaenoic acid (DHA). In the body, EPA participates in the formation of signaling molecules that influence inflammation, thrombosis, and vascular function, often with anti-inflammatory effects compared with other fatty acids.

Health considerations and safety: EPA is studied for lowering blood triglyceride levels and for potential effects on cardiovascular risk, inflammatory conditions, and mood disorders, though results vary by condition and dosage. Typical therapeutic uses involve moderate to high doses of EPA+DHA rather than EPA alone. Side effects are generally mild but can include gastrointestinal discomfort and a fishy aftertaste; high doses may slightly increase bleeding risk, especially in people taking anticoagulants. Pregnant women and others should follow professional guidance, and supplementation should use regulated products to limit contaminants.
