The marine oil in Metagenics formulas is processed in Norway, but the fish may also come from elsewhere. Fish oil resellers may imply that their product is made exclusively from fish from Norwegian waters. In truth, the majority of wild-caught fish for supplements comes from off the coast of South America (Peru and Chile), with smaller amounts coming from Europe, Africa, and the United States. What is the key takeaway point? Don't be misled by slick marketing tactics. The finest raw material sources start with fresh, clean, deep-sea, wild-caught, cold-water fish (from Norway or elsewhere); the oils from these fish should then be further "cleaned" through advanced processes to remove any concern of harmful levels of potential contaminants.
