Optimal Wellness Our classic Arctic Cod Liver Oil has always been derived from 100% wild Arctic cod—no other fish oils or synthetic additives are ever used. Unlike fermented oils, our cod liver oils are manufactured to eliminate free fatty acids and prevent rancidity. They support the heart, brain, and nervous system, and promote optimal immune system function.* Exceptionally Pure Fish Oil Every batch of Nordic Naturals fish oils is tested by a third-party certified lab for environmental toxins, including heavy metals.
