 In one of my videos last year, I noted that the fish oil distillation process was found ineffective at removing all the industrial contaminants from fish oil, so even quote-unquote PCB-free fish oil may be anything but. Isn't there a law in California, though, that makes it illegal to sell toxic substances that cause cancer birth defects without at least a warning label? I've never seen such a label on fish oil, and neither did the Environmental Justice Foundation, so they sued CVS, GNC, Rite Aid, along with the major fish oil manufacturers. To do so, of course, they had to prove the fish oil you find in stores actually contains PCBs, so they went out and grabbed 10 and tested them. Some had 70 times the PCBs of others, and 240 times the toxicity. This is why we should get our long-chain omega-3s without any risk of toxins by choosing microalgae or yeast-based EPA DHA supplements. Nutritionally equivalent, a safe and convenient source without the toxic waste.
