Is fish oil fish oil?

[garagedoor79]

I just got out of the drug store looking over fish oil capsules. They had cod liver oil. Salmon Oil. Mixed 3 species oil - mackeral, sardine and something else. Omega 3-6-9 oil. And so on.

My question is are all these more or less the same to add in my diet? One better than the other or any other factor I can use to choose one over the other?

Looking over the labels, none talked about grams of fat, just IU's of vitamins.

Thanks!

no they're not interchangable. sorry it took me so long to answer, i meant to respond days ago and forgot. cod liver oil is much lower in epa and dha than my fish body oils. a single 1000mg fish body oil from gnc contains 120 mg and 180 mg epa/dha (can't remember which has which amount). they do vary tho

In the sense that both are fish oils, yes. Cod liver oil tends to have a lower epa/dha content. Just look for a brand/bottle that gives you the most epa/dha for your money.
