Your question: I take Twinlab Norwegian cod liver oil everyday for Vitamins A and D and the fish oils. Could it be as toxic as liver as Moreless had said. The Twinlab label says it's heavy metals and PCB free. Could it have other toxins?
Answer: We may need to consider several factors to determine if Cod Liver Oil is Toxic or not?
First the Liver detoxifies Toxins from our body and the bodys of all animals!
Thus the younger the animal and the Less Polluted environment this animal is grown in may mean the Less Damage the Liver may be.
Cod fish are not Large or Old fish and if they are harvested in the Cold waters of the ocean they may not be subjected to the Pollution of warmer waters!
Major Cities are not located around the Coldest waters of the ocean, thus Less Pollution!
Thus because Cod Fish are smaller and younger Fish than Fish, which may grow much Larger, the Cod may not accumulate as much Toxins as Large and Older Fish!
Cause and Effect!
