Cod Liver Oil

Cod liver oil is a type of fish oil derived from the liver of cod fish. It is extracted from the liver and then purified. It is a source of omega-3 fatty acids, vitamin A, and vitamin D.

Cod liver oil is often added to foods as a source of beneficial nutrients, particularly omega-3 fatty acids and vitamins A and D. It can be found in dietary supplements and some fortified foods, though its use in processed foods is less common due to its distinct flavor.

Cod liver oil is recognized as a source of essential nutrients. The U.S. Food and Drug Administration (FDA) considers it a dietary ingredient. International bodies like the European Food Safety Authority (EFSA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have evaluated fish oils. While generally considered safe as a food ingredient, excessive intake of vitamin A and D from cod liver oil can lead to toxicity, as these are fat-soluble vitamins.
