Omega-3 fats: Sources, benefits and forms
Fish oil or cod liver oil? Understand the differences
Cod Liver Oil
Cod liver oil is a dietary supplement derived from the liver of cod fish. As with most fish oils, it contains omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and also vitamin A and vitamin D. Cod liver oil can be obtained from eating fresh cod liver or by taking supplements, for a natural source of vitamins A and D and omega-3 fats.
