Cod Liver Oil

Cod liver oil supplements provide the omega-3 fatty acids EPA and DHA, together with naturally occurring vitamin A and vitamin D. They are available as liquid oils, softgels and capsules in different concentrations and flavours. Compare the amounts of EPA, DHA, vitamin A and vitamin D per serving rather than looking only at the total oil quantity. Avoid unknowingly combining cod liver oil with several other supplements containing high amounts of vitamins A or D. High intakes of preformed vitamin A can be harmful, particularly during pregnancy, so pregnant people or those using medication should seek professional advice before taking these products.
