Fish oil is usually compared for EPA/DHA concentration and broad supplement choice, while cod liver oil adds a vitamin A and D label-check layer that shoppers should review carefully.
Decision table
How to choose between them
Source
Both are fish-derived, but cod liver oil specifically comes from cod liver and may include vitamins A and D.
Label priority
Compare EPA/DHA per serving first, then review vitamin A/D amounts if using cod liver oil.
Format
Fish oil appears in softgels, capsules, and liquids; cod liver oil is often liquid or softgel and may need extra storage checks.
Best fit
Choose fish oil for broad EPA/DHA comparison; choose cod liver oil only when vitamin content and serving guidance fit the shopper's context.
