Nordic Naturals (Watsonville, CA) defended its cod liver oil products as posing no threat to consumers, the company said on December 1, in light of a report suggesting cod liver oil may be detrimental to humans due to its high vitamin A content.

The initial report, titled: “Cod Liver Oil, Vitamin A Toxicity, Frequent Respiratory Infections, and the Vitamin D Deficiency Epidemic” was published on November 11 in the Annals of Otology, Rhinology & Larynology by 16 members of the supplement fraternity.

“The issue that is cited by this group is based on the fact that almost all cod liver oil in the market is being supplemented with synthetic or natural vitamin A, standardized to certain levels, which is why it is assumed that all cod liver oil has high levels of vitamin A," said Karin Yien, MD, Nordic Naturals chief medical adviser.

"This is not true for the Nordic Naturals brand. We have always had low, healthy levels of natural vitamin A in our cod liver oil; consequently, we do not add Vitamin A to any of our cod liver oil products.”
