Krill supplements are the fastest growing omega-3 category today. But is it a sustainable source? Yes. Actually, the krill fishery is one of the best managed fisheries in the world. For the last several years, Aker BioMarine has been working with WWF-Norway to ensure the sustainable management of krill in the Antarctic. In fact, Aker BioMarine’s Superba Krill is certified for its sustainable harvest and 100% traceability.
