Ultra refined fish oil is one of the best forms of this powerful health supplement, for a variety of reasons. There are many kinds of fish oil available in the market. Fish oil supplements are graded on the basis of production and ingredients. There are primarily three kinds of fish oils available today and they vary in quality.
Cod Liver Oil
Even though cod liver oil has several nutritional advantages, it is not considered to be as good as ultra refined fish oil. For most people who take these supplements, cod liver oil is recommended only when ingested in small amounts. It contains high levels of vitamin A and the fish processed for cod liver oil may not always be free of all contaminants. If consumed in large doses, it can prove to be hazardous to human health. One teaspoon of cod liver oil has 500mg of omega-3 fatty acids but it is also known to have the maximum amount of contaminants as compared to other kinds of fish oils. Contaminants include PCB, DDT and organic mercury.
Health Food Fish Oil
The quality of health food fish oil is a lot closer to that of ultra refined fish oil as it is extracted from only specific kinds of fish – namely salmon. They are mostly available in softgel capsules and do not taste very nice. This type of fish oil is also available in a cholesterol free version. Health food fish oils undergo a purification process that is slightly more stringent than those undergone by cod liver oils. The process known as limited molecular distillation ensures that enough cholesterol is removed from the final product so that it can carry the cholesterol free label.
Fish oil concentrate is also a kind of health food fish oil and it is purified even more. It contains ethyl esters of fish oil with even lesser contaminants. With a high concentration of omega-3 fatty acids, a one gram softgel capsule of health food fish oil has 300mg of omega-3 and one capsule of fish oil concentrate has 500mg of omega-3.
Pharmaceutical Grade Fish Oil
This is also known as ultra refined fish oil and provides people with the best quality of omega-3. After undergoing specialized processes, the final product is the most refined version of fish oil that can be produced. Special equipment detect the slightest presence of contaminants and thus pharmaceutical grade fish oil is known to be thousand times purer than health food fish oils. Ultra refined fish oil contains the maximum amount of omega-3 fatty acids with one gram comprising of 600mg omega-3.
