A registered dietitian reveals why this fish oil stands out from the pack.
High in nutrients, cod liver oil is a popular dietary supplement derived from fish. As with most supplements, cod liver oil is not regulated by the U.S. Food and Drug Administration (FDA) but some doctors and nutritionists do recommend these supplements for various benefits. Registered dietitian Madeline Basler weighed in on the potential advantages of cod liver oil consumption.
What Is Cod Liver Oil?
Cod liver oil is the oil extracted from one type of fish — the Atlantic or Arctic cod. It is a dietary supplement that is typically sold in liquid or gel capsule forms and can be consumed on a daily basis. The recommended intake can vary but the typical serving size of cod liver oil ranges from one teaspoon to one tablespoon. Because it can have a strong fish odor and taste, some varieties of cod liver oil may contain added flavorings, such as lemon-lime, orange, and strawberry flavors.
