How Cod Liver Oil is Harvested

The quality and location of harvesting are especially important. The cod can be farm-raised or wild-caught. You should ensure the manufacturer is transparent about water quality if it is farm-raised. Even though you can get it farmed, it is best to get it wild-caught from the Arctic Circle. Be sure that it is also pure virgin cod oil for the best quality.

When the cod is harvested, the livers are separated from the rest and ground into a slurry with water. It then sits, and the oil rises to the top and then separates. You can get cod liver oil cold or hot processed. You want a high-quality cod that has been cold-processed. If not, the liver oil can become rancid and lose vitamins and minerals. You can also find fermented cod liver oil. However, in this case, fermented just means it's rancid or putrefied.
