About this ingredient
Cod Liver Oil is a nutritional oil extracted from the liver of cod fish, particularly species such as Atlantic cod (Gadus morhua). It is a traditional dietary supplement and a source of omega-3 fatty acids, including EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Depending on the product and processing method, Cod Liver Oil also provides vitamins A and D.
Omega-3 fatty acids contribute to normal cell function and support several processes in the body. DHA is an important structural component of the brain and retina, while vitamin D supports calcium absorption and bone health. Vitamin A contributes to normal vision and immune function. The exact nutrient content varies by product, so consumers should check the label rather than assume all Cod Liver Oil supplements provide the same amounts.
Cod Liver Oil is commonly available in softgel capsules and liquid form. It can help supplement dietary omega-3 intake, particularly for people who do not regularly eat oily fish. However, it should not be considered a treatment for a medical condition, and the evidence for specific benefits depends on the nutrient, dose, and individual needs.
Because Cod Liver Oil may contain vitamins A and D, taking it alongside multivitamins or other supplements containing these nutrients can lead to excessive intake. High amounts of preformed vitamin A can be harmful, especially during pregnancy. Consult a healthcare professional before use if you are pregnant, breastfeeding, take blood-thinning medication, or have an existing medical condition. Follow the product's serving instructions and avoid exceeding the recommended amount.
