If fish is toxic, why is Omega Sufficiency® fish oil safe to consume?

Omega Sufficiency® is extracted in a licensed pharmaceutical grade facility from cold water anchovies and sardines that are the purest, least toxic source of omega 3 fish oil. Our oil is purified in a non-chemical molecular distillation process that removes even trace amounts of heavy metals, PCBs, organochlorides, and organophosphate pesticides resulting in the safest, purest source of EPA/DHA fish oil possible. As the oil is purified it is immediately infused with our natural, proprietory antioxidant blend consisting of rosemary extract, ascorbyl palmitate and natural mixed tocopherols and then immediately bottled in a dark glass bottle with a patented spill-proof, threadless cap. This process ensures the greatest oxidation protection possible. There simply is not a better, purer source of EPA/DHA omega 3 fatty acids in the world as our third party testing results indicate.
