Fish oil can be obtained from all species of fish, but not all of them contain a very high amount of omega-3 fatty acids, since different species of fish eat various things. That is why buying a product containing omega-3 fatty acids it is important to pay attention not only to the volume of fish oil in a given product, but most importantly to the actual quantity of omega-3 fatty acids inside. According to nutritional recommendations developed by Scandinavian institutions, omega-3 fatty acids should constitute 1% of the energy in our diet, which equals approximately 1-1.2 grams of unsaturated fatty acids a day.
Cod stores fat in its liver, along with vitamins A, D and E, which are soluble in fats. Our company has been producing cod liver oil since 1854. From February to April the annual Arctic cod migration takes place, when the fish lay eggs along the Norwegian coast. The cod are harvested by small fishing boats and their fresh livers are delivered to oil manufactures located along the coast. Undergoing delicate processing using steam, the livers provide an oil rich in omega-3 fatty acids. The material obtained in such a way is immediately sealed in nitrogen. Nitrogen is heavier than oxygen that is why it covers the oil in a protective coating. Oxygen is the oil’s worst enemy, because it causes its oxidation. Rancid oil, is the kind of oil which to a large extent was oxidized. Our nitrogen-sealed oil is then transported from manufacturing plants located on the Western coast of Norway to our factory located along Peter Möllers vei in Oslo. Before the delivered material reaches the production line its oxidation degree and omega-3 fatty acid content are checked. If it meets the quality standards, it continues on its journey: some saturated fats, which are naturally present in the cod liver are removed, proteins are also removed (that is why people who are allergic to fish can consume cod liver oil), along with water remaining from the processing stage, as well as possible contaminants and products from the oxidation process. Next we check whether the obtained cod liver oil contains the appropriate amount of omega-3 fatty acids, as well as vitamins A, D and E.
Before our cod liver oil is delivered to shops all across Norway it is bottled. In order to once again secure the cod liver oil, before closing, the bottle mouths are covered in nitrogen. Originally sealed cod liver oil is valid for consumption for a period of two years. As soon as the bottle is opened its expiration date is lowered by 3 months, since the oil is exposed to oxygen. The opened product should be stored in a refrigerator. A teaspoon of cod liver oil (5ml) contains 1.2 grams of omega-3 fatty acids.
Our firm, as well as other manufacturers, offers omega-3 fatty acids in capsule form as well. Since one capsule is rather small, there is a need to choose the kind which contains a lot of omega-3 fatty acids, in order for one capsule to contain high fatty acid concentration. All our capsules contain fish oil from anchovies and sardines, since these species of fish which live in cold seas bordering Chile and Peru, contain a particularly high amount of omega-3 fatty acids, higher than cod livers. Suppliers of fish oil, from which our products are made, were carefully selected. They must fulfill a number of requirements concerning both the quality of materials offered as well as regulations regarding sustainable fishing. The material supplied to the Oslo factory, as well as the material from which fish liver oil is made, must meet the requirements regarding oxidation process as well as quality standards, before it is accepted by us. When a specific batch is approved, it undergoes virtually the same process as the material from which cod liver oil is produced. This process should ensure the oil’s purification and preserve its quality. Our recipients are more and more demanding when it comes to the degree of purification of our products. In order to show that we respect our clients we have developed quality standards verified by DNV-GL, as an independent third party.
