These are companies that most likely molecularly distill their fish oil though

That means they use aging diseased fishes or must obtain fishes from contaiminated waters in order to have to go through that process.

Good fish oil should never be moleculary distilled whatsoever because it changes the molecules of the fish oil and you will never benefit from it if it goes through heavy processing.

Make sure the fish oil is from pristine waters so that it doesn't have to go through a purification process thus maintaining all the benefits that real fish oil should.

With all due respect, I don't think it is possible to guarantee
fish have been taken from pristine waters. I don't think that exists today. I would wonder about a place that guarantees pristine fish.

If you look on the ingredients for that product -- 4 capsules provide 45 mg of EPA.... that means in order to achieve therapeutic levels, you'd need 40 of them. Typically salmon oils are very low in Omega-3 levels.

I think this is rather beyond the general understanding and use requirements of most people.

It is good you are using something... but what you are using is not very potent.

do you know how much epa is in one fish? If you consumed one piece of fish a day would that give you how much of epa or would it depend on the type of fish?

I thought farm raised salmon were low in omega 3 as opposed to wild salmon.

This is a good nutrition website. One can look up many foods on it.

for example-- farmed salmon, raw:

Fresh:

Notice there is a difference. However, the fish have far more omega-3's than the fish oil capsules.

I think GNC fish body oils 1000 is not a bad fish oil to take. even though it got related GNC fish body oils got incomplete in the study.
