Decisive for the quality of the fish oil is the right selection of the raw material – i.e. the fish. Mainly small deep-sea fish from wild catches such as sardines, mackerel and anchovies are caught and immediately processed and cooled on board. The fish come exclusively from the Atlantic. The NORSAN fish oil is not extracted as a by-product from the fish liver, but directly from the fish flesh. Often there are only 4 hours between the catch and the transfer to the production.
