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.
