What Is Cod Liver Oil?

Cod is a type of fish which tends to be located north of forty degrees north latitude. Thus, people know it as one of several cold water fish, which are prized for their abundance of omega-3 fatty acids. Cod liver oil is an oil which comes from from the livers of these fish for more than 1200 years.

The Möller Process was the standard means of processing cod liver oil after about 1850. In this process, the livers were mixed with water, ground into slurry, and simmered until the oil rose to the top. The oil was skimmed off, purified and bottled for use. Modern methods make use of Cold Flotation, Pressure Extraction, and Pressure Cooking. Once the oil is extracted, it is typically put into capsules. However, you can occasionally purchase it as a light or brown oil in northern regions of the world.

Cod liver oil presents a pretty powerful nutritional profile. For each teaspoon (4 grams) it contains:

• Vitamin A 4500 IU or 90% DV;
• Vitamin D 4500 IU or 113% DV;
• Omega-3 fatty acids 888 mg;
• Omega-6 fatty acids 42.1 mg.

The nutritional benefits of cod liver oil are certainly impressive, as we’ll see in a moment. But they are not all inclusive cures. It is still better to consult a health care professional for advice and treatment for specific health issues.
