Cod Liver Oil Supplements

About cod liver oil

Cod liver oil comes specifically from the liver of cod, which is why it’s naturally rich in vitamin A and vitamin D as well as the omega-3s EPA and DHA. That combination is what sets it apart from regular fish oil, which is pressed from the flesh of oily fish and is lower in those vitamins. People take it to help support heart, bone, immune, and eye health, and it’s a popular way for Canadians to top up vitamin D over the darker months.

Vitamin A and D — the thing to know

Because cod liver oil naturally contains vitamin A and vitamin D, the amount of those vitamins matters when you choose one:

• Standard — provides vitamin A and D alongside the omega-3s.
• Low vitamin A — for people who want the omega-3s and D without much vitamin A (handy if you already get vitamin A elsewhere).
• With added D — some formulas boost the vitamin D further.

Forms we carry

• Liquid — the traditional form; easy to take by the spoonful, often in lemon or mint to soften the taste.
• Softgels (gems) — no taste, pre-measured, easy to travel with.
• Kids’ versions — gentler-tasting liquids made for children.
• Sourcing — Norwegian, Icelandic, and Arctic cod are common; some brands offer raw or fermented options.

How to choose

Decide between liquid (traditional, easy to adjust) and softgels (taste-free, convenient), then check the vitamin A and D amounts per serving — especially if you take other supplements containing them. Lemon or flavoured liquids help if taste is a concern.

An important note on vitamin A

Cod liver oil is naturally high in vitamin A, and vitamin A is one you can get too much of — it builds up in the body, unlike some vitamins. If you already take a multivitamin or other supplements with vitamin A, add up the total so you don’t go over the recommended amount. This matters especially in pregnancy, when too much vitamin A isn’t recommended — so if you’re pregnant or could be, check with your healthcare provider before taking cod liver oil.
