Dietary Sources of eicosapentaenoic acid

EPA is found in cold-water fatty fish, including salmon, tuna, mackerel, sardines, shellfish, and herring. Although some of these fish contain low levels of mercury, according to the Food and Drug Administration (FDA) eating several servings of fish each week poses no risk to healthy people and offers many health benefits.

Women who are pregnant or planning to become pregnant should avoid Atlantic mackerel, shark, swordfish, and tilefish, and eat less than 6 oz. of white albacore tuna per week. These fish tend to be higher in mercury.

High-quality fish oil supplements made by manufacturers who test for mercury and other toxins do not have the same risk of mercury contamination. Read labels carefully and check for purity, or ask your doctor to help you find the best quality fish oil supplement.
