NKO® the inventor of krill oil

NKO was the world's first krill oil B2B brand that launched a new market of krill oil supplements that have seen meteoric growth for nearly two decades. Some of the first research projects to elucidate the health benefits of krill oil were performed in the 1990s and the subsequent promising results led to the launch of NKO in 2003.


What sets krill oil apart in the supplement market?

Pure and plentiful

From the pure waters of Antarctica

Krill are shrimp-like crustaceans that reside in all oceans across the world. Antarctic krill (Euphausia Superba) live in the pure and pristine waters of the Antarctic Ocean and represent one of the most abundant marine biomasses on the planet.

Due to the pristine and untouched nature of the Southern Ocean surrounding Antarctica and its low position in the food chain, krill contain an extremely low level of environmental toxins.

Krill feed on marine algae that produce the essential omega-3 fatty acids EPA and DHA, which are integrated and absorbed by the krill's body. These omega-3 fatty acids can then be extracted into krill oil which carries other beneficial components such as phospholipids, choline, and astaxanthin. It is this particular combination of elements that makes krill and krill oil unique in the dietary supplement and omega-3 market. 

Unique structure

A natural multi nutrient

Krill oil extracted from Antarctic krill is a pure and natural complex of nutrients that all work together to support your health via the powerful combination of marine phospholipids of omega-3 EPA and DHA, choline and astaxanthin.

This combination of important nutrients is the basis for krill oil’s uniqueness. Each of krill oil’s major components have shown to have beneficial effects in the body’s cells and tissues. This is the basis of its health benefits in many bodily systems and health conditions.

Head-to-toe health benefits

Science and clinical studies

Aker BioMarine has conducted more than 50 research projects on krill oil, among them many clinical studies demonstrating krill oil health benefits on areas such as heart and joint health, sports and women's health.

Current research on krill oil is being performed to explore its benefits for lupus, sports performance and skin health.

Sustainable Harvesting

One of the most sustainable fisheries in the world

The krill fishery is considered to be one of the most regulated and sustainable fishery in the world. NKO® is certified for sustainability by the nonprofit marine conservation group Friend of the Sea.
