Overview

Eicosapentaenoic acid (EPA) is an omega-3 fatty acid. It's found in the flesh of cold-water fish, including mackerel, herring, tuna, halibut, salmon, cod liver, whale blubber, or seal blubber.

EPA is used as a prescription medicine to reduce triglyceride levels. As a supplement, EPA is most commonly used for heart disease, preventing adverse events after a heart attack, and depression. It is also used for chemotherapy-related side effects, recovery after surgery, and many other conditions, but there is no good scientific evidence to support many of these uses.

Don't confuse EPA with similar fatty acids, such as alpha-linolenic acid and docosahexaenoic acid (DHA), as well as with oils like algal, krill, or fish oils, which contain both EPA and DHA. Most available research involving EPA is from the use of fish oil products containing variable combinations of EPA and DHA. See the separate listings for algal oil, alpha-linolenic acid, DHA, fish oil, and krill oil.

How does it work ?

EPA can prevent the blood from clotting easily. These fatty acids also reduce pain and swelling.
