The Dutch Arctic Blue products (liquid or capsule) are plant-based (based on algae oil) or made from the fillet trimmings of wild salmon, wild pollock, or wild cod. In addition to the fillet for the supermarket, one cod yields no less than 1 bottle (150 ml) of oil or 250 capsules. Whereas for many fish oils entire shiploads of sardines and anchovies are put through the mincer, no extra fish are caught for Arctic Blue . You have the guarantee that we do not eat dolphins, seabirds, sea lions, or whales. And the guarantee that there are no adverse effects on the oceans, the environment, or the local population. This approach has earned us the MSC label in the Netherlands, which nature organizations say is the best guarantee for sustainable fishing.
