Gen, I use Carlson brand Norwegian fish oil, it has a purity guarentee, FDA tested, AOAC tested using international protocols ..regularly tested for levels of mercury, cadmium, lead, PCB's and 28 other contaminants. Did not see anything on their website for sustainabilty practices which us important but I do see that with Nordic.

"To address this, fish oil manufacturers use a process called molecular distillation to remove the toxins from the oil. When done correctly, molecular distillation is capable of reducing the toxins in fish oil to levels considered to be safe by the EPA and other agencies.Although almost any fish oil manufacturer will tell you their product is free of these toxins, independent lab analyses tell a different story. Just last month (March, 2010), a*lawsuit was filed*in California court against the manufacturers of ten popular fish oils because they contained undisclosed and (possibly) unsafe levels of contaminants. "

That's from an older article but I am lazy I am sure it still holds weight today.

I have not asked Carlson for a COA have you seen one for Nordic ? Any published testing by an independant certified lab or have you requested this info from Nordic ? If I can find that info I will switch. All the info for epa, dha, k , d etc that go with selecting a fish oil get overwhelming oh my goodness.

I stopped taking fish oil before my surgery and have not ressumed yet. But I want to be sure what I am getting, Carlson doesn't run cheap either... $44 for 500ml in Canada.

Christina, you are open to anything under the sun for treatment if it helps. You never scoffed at my success with gluten and were hugely supportive to me through all my alternative ideas. And one of my biggest supports for getting off my meds and at that time the forum was not as open to that as it is today.
