Special qualities of Neptune Krill Oil

Top-quality omega-3: highest bioavailability

Blood omega-3 levels are increased more after ingestion of NKO than after ingestion of equal amounts of omega-3 (120 mg EPA+DHA) in the form of fish oil or omega-3 ethyl esters. Very fascinating! It proofs that NKO provides higher bioavailability compared to fish oil or ethyl esters, reflecting a superior quality.

This difference in absorption rate can in part be explained by a difference in chemical structure of the omega-3 fats. Fish oil is a triglyceride source of omega-3 fatty acids, NKO a phospholipid source and ethyl esters are separate fatty acids. Phospholipids are more soluble upon ingestion and, to a certain extent, can be absorbed undigested. Both advantages are not applicable to the other omega-3 sources.

Neptune Krill Oil provides more than just omega-3 fatty acids

To come back to the Western dietary pattern: it is known that Westerners consume omega-6 fatty acids in excess. This is due to the consumption of vegetable oils such as safflower, sunflower, corn, sesame and peanut oil, and because omega-6 fatty acids are used as flavour enhancers in those irresistible cookies, snack meals and other refined foods.

Therefore, it is quite clear that we should consume more omega-3 fatty acids in order to restore the balance between omega-6 and omega-3 in our body. This is more easily done with NKO than with standard fish oil since NKO contains 15 times more omega-3 than omega-6 while standard fish oil has only 3 times more omega-3 than omega-6.

Neptune Krill Oil has a high stability

Besides the omega-3 fatty acids, EPA and DHA, NKO also contains a cocktail of antioxidants. These antioxidants are naturally present within the oil blend extracted from the krill. They are not added.

The advantage of such a cocktail is most obvious. Omega-3 fatty acids are particularly sensitive to oxidation (to turning rancid), meaning that they are easily destroyed when combining with oxygen. To prevent omega-3 fatty acids from oxidation omega-3 supplements are enriched with vitamin E (as antioxidant). With its natural antioxidant cocktail NKO clearly is in a favoured position. 

Neptune Krill Oil's phospholipids are important fats

Phospholipids are components of every cell in our body, since together with cholesterol they make up the cell envelope. The fact that NKO's omega-3 fatty acids are in the phospholipid form is a major advantage. NKO not only increases the omega-3 level in our body but also adds to a rise in phospholipids.

Choline as precursor of acetylcholine

One gram of NKO contains 73 mg choline. Choline helps to maintain normal liver function and normal metabolism of homocysteine and fat.

Genuine binding of omega-3 to phospholipids and astaxanthin

After oral intake, more omega-3 fatty acids are absorbed into the blood circulation if derived either from NKO than from an NKO imitator. The imitator consisted of a mixture composed of individual omega-3s, isolated phospholipids and added astaxanthin. The better absorbability of NKO as compared to the imitator is due to the actual binding of omega-3s to phospholipids and astaxanthin within the NKO.
