Space55, you want to make sure you buy a high quality fish oil derived from sardines, mackeral and anchovies because they are low on the food chain and don't accumulate as many toxins. In canada, all fish oils have to reach certain standards. Not sure the deal in the states however with oils the addage is true that you get what you pay for.

NOW brand is good (they have a really good high potency one)
Nutra Sea is superb, caught in norwegian waters where the pollution is much less
Renew Life has one with lipase to get rid of "Fishy burps" if that is a problem for you

Rule of thumb is to always buy your supplements from a health food store, you will get a far superior quality than a drug store brand.
Hope that helps!

If you're concerned about mercury, rather than buying fish oils for your Omega oil intake, why not buy vegetable sourced oils. You can get an organic vegetable source oil such as organic golden flaxseed oil which simply avoids the mercury problem altogether.

The reason to choose fish is because they have DHA, something that vegetable omega 3 sources do not have. This is not to say that vegetable sources are not healthy, but fish is definitely the way to go.

There is no 100% omega 3 source.

Even fish oil is about 25% omega 3.

Another good low food chain fish oil is salmon (also high in omega 3)

Good luck!

eat paintballs...lol

I like Nordic Naturals. I have been taking them for a long time and they seem committed to purity. I wish I was a scientist and could analyze everything I take- since supplements are not regulated (although I am not sure Government regulation would be such a good thing) who knows if a companies integrity backs up their marketing. I have an idea to just pray over my supplements like I do my meals.
