Fish Liver Oil

Fish liver oil is a supplement derived from the livers of fish, particularly fatty species like cod. It is rich in essential nutrients such as vitamin A, vitamin D, and omega-3 fatty acids. These nutrients support healthy vision, immune function, bone health, and cardiovascular health. Because these vitamins and omega-3s are vital for overall wellness and are often lacking in modern diets, fish liver oil is used to help prevent deficiencies. However, it should be taken in moderation, as excessive intake of vitamin A and D can be harmful.
