Liquid Fish Oil

Guides and comparisons Omega-3 & fish oil: how to compare EPA and DHA content

Liquid fish oil and omega-3 oil in bottles from 30 ml to 500 ml, some lemon flavoured and some made for children. A serving is measured by volume, and the label gives the omega-3 for one serving, not for the whole bottle. Compare the EPA and DHA per serving, the serving volume and the number of servings a bottle holds. Flavoured oils list their flavourings and any sweeteners in the ingredient list.

Frequently asked questions

How many servings are in a bottle of liquid fish oil?

Divide the volume of the bottle by the serving volume on the label to get the number of servings. The omega-3 figure on the label refers to that serving, not to the whole bottle, so compare two bottles per serving and not per bottle.

Are children's omega-3 oils listed with liquid fish oil?

Yes. Liquids are not split by age group, so titles marked kids or baby are listed here. Each label gives the age group the product is intended for, its serving and its warnings, so read those lines on the label of each bottle.

How should liquid fish oil be stored after opening?

The label gives the storage conditions and, where they apply, how long an opened bottle can be kept. Follow the instructions printed on the exact product, since they can differ between oils and brands, and check the date mark on the bottle.
