Fish oil supplements are usually made from mackerel, herring, tuna, halibut and salmon but many customers often wonder the differences between fish oil and cod liver oil.
Cod liver oil and fish oil are similar, but cod liver oil has much higher levels of vitamins A and D.
Derived from liver of cod fish and considered one for the best sources of omega-3, cod liver oil has high levels of the omega-3 fatty acids, EPA and DHA, and very high levels of vitamin A and vitamin D.
Cod liver oil is widely taken to ease the pain and joint stiffness associated with arthritis, and has also been clinically proven to have a positive effect on heart, bones, as well as helping to nourish skin, hair, and nails.
When purchasing cod liver oil supplements, it’s important to know the quality of the cod you’re buying. Arctic Cod (Skrei) has the highest DHA, vitamin A, and vitamin D content of any cod species and has been used for years. In fact, cod liver oil was part of the Viking diet.
The Skrei Standard is a stamp of quality by the fisheries industry and the Norwegian Seafood Export Council (NSEC). It provides a quality standard that defines first-class skrei, and distinguishes it from other products made from cod.
The requirements to be awarded the Skrei label include approval of production plant, species definition, country of origin of fishing grounds, handling of the catch onboard the fishing vessel, freshness (Arctic cod must be packaged within 12 hours of catching), refrigeration (cod needs to be stored on ice at a temperature between 0° and 4° Celsius), size sorting, visual impression and packing.
