Krill are small crustaceans, and are found in all the ocean globally, mostly in polar waters. They belong to the same genus as shrimp, lobsters, and crabs. There are currently more than 80 known species of krill. Antarctic krill (Euphausia superba) can be fished because they gather together in huge swarms and are present in open waters. Krill swarms can be up to 6 kilometers in length, with a maximum density of 1 million krill per cubic meter. Unlike fish, which may be susceptible to environmental pollutants, Antarctic krill are low on the food chain and live in a very pure environment. 

Antarctic krill, the longest krill species, can grow up to 6 cm in length and live up to 5-6 years. Krill, filter feeders, mainly feed on phytoplankton. Phytoplankton is rich in nutrients, and krill that feed on it can produce a lot of fatty acids. Krill constitute the vital food source for Antarctic animals such as penguins, terns, and blue whales due to the rich content of Omega-3 fatty acids, antioxidants, proteins, vitamins, minerals, and trace elements. 

Most of Omega-3 fatty acids in krill oil are associated with phospholipids, which also contain choline molecules. Astaxanthin, as an antioxidant, plays a crucial role in protecting Omega-3 fatty acids, and makes krill oil maintain a long-term nutritional activity and freshness. 

As the fact that Antarctic krills live in the pristine Southern Ocean where has extremely low environmental pollution, as well as they are at the bottom of the food chain, Antarctic krills have no toxin accumulation like fish and seals. Therefore, krill oil is known for its exceptional purity.

Omega-3 fatty acids in fish oil are associated with triglycerides. Triglycerides do not mix with water, but form large fat droplets in water that float on the water surface, and this is the main reason for the fishy smell of fish oil. Omega-3 fatty acids of krill oil are associated with phospholipids. Phospholipids are bipolar, with one end being the head group and the other being hydrophilic and hydrophobic chains. In water, phospholipids can form a variety of structures, including micelles and liposomes, which can disperse the fat-soluble components in water, and this also explains why krill oil has almost no fishy smell. 

Moreover, phospholipids are major structural components of cell membranes. As cells’ “goalkeepers”, phospholipids are essential for the proper functioning of all cell membranes, which enable nutrients to efficiently cross the cell membrane and be absorbed directly into the cell. Therefore, Omega-3 with phosphilipds in krill oil has a totally different bioavailability compared with triglycerides. Studies have shown that, the bioavailability of krill oil is up to 98%-100%.

In addition to the complementary effects of phospholipids and Omega-3 fatty acids, phospholipids alone can also deliver health benefits for humans and animals. Phospholipids are particularly crucial for brain and liver metabolism, and lecithin has been shown to have numerous health benefits, such as:

  • Counteract ageing effects; 
  • Reduce the impact of inflammatory diseases; 
  • Improve cognitive function; 
  • Enhance plasma and liver lipid metabolism; 
  • Reduce plasma cholesterol and triglyceride; 
  • Increase HDL cholesterol (“good” cholesterol) in human body; 
  • Lower liver triglyceride; 
  • Prevent alcohol-related liver damage; 
  • Prevent liver fibrosis and cirrhosis caused by alcohol.

Norway is one of the countries with the longest lifespans in the world. Norwegian healthy lifestyle consists of “Three Treasures of Norway”: salmon, berries and krill oil.

The territory of Norway is long, covered with vast forests as well as offering people the gifts of nature – “berries”. Cranberries, blueberries and other berries contain various vitamins and nutrients. NYO3 patented bilberry lutein and NYO3 blueberry lutein are rich of Norwegian berries’ nutrition essence, and they are ideal choices for eye health. 

The cold and clean sea waters along Norwegian coast produces tender and firm salmon and other fish that are rich in nutrients including various vitamins and minerals, calcium, magnesium, zinc, as well as plenty of Omega-3 fatty acids. NYO3 95% fish oil, 80% fish oil, and other fish oil products are made from pure deep-sea fish in the Arctic Circle. These products are popular in Norway.

Besides salmon, Norwegians went to Antarctica to search for better and sustainable sources of Omega-3. Antarctic krill oil, extracted from Antarctic krill, contains unique marine phospholipids, Omega-3, choline, and astaxanthin. It has a higher absorptivity compared with triglyceride Omega-3 in fish oil. Moreover, phospholipid Omega-3 fatty acids are vital in all stages of life and have various health benefits, such as regulating cholesterol, improving arthritis, protecting heart health, and enhancing learning and ability. Therefore, NYO3 Antarctic krill oil series products have become a well-known health product in Norway.

The dosage depends on the reason why you take krill oil. In most cases, the recommended dosage ranges from 500 mg to 1 g (i.e., 1-2 capsules) of krill oil daily. For the nutritional treatment of certain diseases, such as reducing high blood lipids, the dosage can be increased, for example, 2 g (i.e., 3-4 capsules) of krill oil per day. 

Krill oil can be taken daily as a supplement. It is recommended to continuously take krill oil for at least 2-3 months before noticable effects such as increase of Omega-3 index in blood.
