Bottom line: cod liver oil is not just fish oil. It provides EPA and DHA, but it also contains vitamins A and D, so the best product depends on your omega-3 target, your current vitamin intake, and how well you tolerate liquid oils or softgels.

How We Ranked Cod Liver Oil Supplements
Last checked: April 2026
We reviewed current competitors, omega-3 supplement guidance, ConsumerLab cod liver oil references, NIH vitamin A and D context, Amazon availability, and label patterns across liquid and softgel products. Products were scored for EPA/DHA clarity, vitamin A and D transparency, freshness handling, testing signals, taste, format, value, sustainability claims, and direct Amazon affiliate availability.
Products lost points if they hid EPA/DHA totals, made broad health promises, lacked freshness guidance, ignored vitamin A stacking, or did not provide a clean tagged Amazon product URL.

Cod Liver Oil vs Fish Oil
Fish oil is usually chosen for EPA and DHA. Cod liver oil adds vitamins A and D, which can be useful for some diets but unnecessary or excessive for others. That is why label reading matters more with cod liver oil than with many standard omega-3 supplements.
How to Choose Cod Liver Oil
Check EPA and DHA, Not Just “Cod Liver Oil” Milligrams
The total oil amount does not tell you how much EPA and DHA you get. Compare the omega-3 breakdown per serving before deciding whether a product is a good value.
Watch Vitamin A and D Totals
Cod liver oil can add meaningful vitamin A and D. If you also take a multivitamin, prenatal, vitamin D capsule, or liver-based supplement, compare totals before stacking products.
Choose the Format You Will Actually Use
Liquids can offer stronger servings and flexible dosing, but taste and refrigeration matter. Softgels are easier to take but may provide less omega-3 per serving.
Safety Notes
Possible side effects include fishy burps, nausea, loose stool, heartburn, and fish allergy reactions. High intakes can raise vitamin A or D exposure and may affect bleeding risk. People who are pregnant, trying to conceive, taking anticoagulants, preparing for surgery, or managing chronic medical conditions should ask a qualified clinician before using cod liver oil.
Bottom Line
Tropical Oasis Icelandic Cod Liver Oil is our best overall liquid pick. Nordic Naturals Arctic Cod Liver Oil is the premium brand choice, Carlson softgels are the convenient softgel option, and Carlson 1100 mg is the higher-omega liquid pick.
