Fish oil production does not just provide one type of end product. In fact, there are also other grades of fish oil being produced. The three types of fish oil produced today depend on their level of quality.

Cod Liver Oil
Cod liver oil, despite its popularity as a nutritional supplement, is considered as a low quality grade of fish oil. It may only be used in small amounts as an ideal supplement since this form of fish oil may contain certain contaminants. Cod liver oil is also known to contain high levels of vitamin A which can be toxic to humans in large doses.

One teaspoon of cod liver oil contains 500 mg of long chain omega 3 fatty acids. Cod liver oil contains the highest levels of contaminants which may include DDT, PCB’s as well as organic mercury. Taking this type of fish oil may not be safe in large quantities.

Health Food Fish Oil
Better quality grade fish oil is one that is sourced from a particular species of fish such as salmon. Most of these health food grade fish oil are usually available in soft gel capsules because they still carry with them a very poor taste profile. There is also a cholesterol free version of this type of fish oil grade.
