Fish oilIs cod liver oil the same as fish oil?
Updated 4 Nov 2026
Short answer
No. Both contain EPA and DHA, but cod liver oil also contains vitamins A and D, in amounts that vary from product to product.[1] Both vitamins can be harmful in excessive amounts.[1]
People who already take vitamin A or D, or who are pregnant, should ask a doctor or pharmacist before they use cod liver oil.[1]
