Where It Grows

Cod liver oil is not 'grown' in the conventional sense as it is a type of oil obtained from the liver of cod fish. Cod fish are found in colder waters and deeper sea regions in the North Atlantic, including the coasts of Norway, Russia, and Canada, and around the United Kingdom and Ireland. These fish are also found in the western North Atlantic around Greenland and Newfoundland. The oil is extracted from the liver of the fish after they are caught.

Best Way to Eat

Cod liver oil is most commonly consumed in capsule form as a dietary supplement, due to its high contents of omega-3 fatty acids, vitamin A, and vitamin D. It can also be taken in liquid form, though its strong and distinctive taste may not be appealing to everyone. Some people choose to mix it with a little juice or water to make it more palatable. It's best to follow the dosage instructions on the package, as overconsumption can lead to vitamin toxicity. It is not typically used in cooking due to its strong flavor and the fact that heat can degrade some of its nutritional benefits.
