K•REAL® krill oil offers unique benefits unmatched by any other krill oil. It is produced using Enzymotec’s innovative MSO® technology, a proprietary process that results in the only krill oil that meets the highest standards in both freshness and quality. The numerous benefits of MSO® technology, and the krill oil produced by this technology, include:
- REAL quality
- REAL purity
- REAL potency
- REAL consistency
The quality parameters used today for measuring krill oils are mainly chemical parameters that are tested during shelf life. However, those parameters do not refer to the changes in a krill oil’s biological activity after consumption. Establishing an industry first, Enzymotec has defined quality parameters for krill oil through the entire supply chain, from its harvesting until it reaches the digestion system. By using a simulation model for measuring the biochemical quality of krill oil in the digestion system, Enzymotec sets biological quality parameters to be used on top of the standard ones.
A number of parameters are typically used to test fishery products, indicating the freshness and quality of these products. Those same parameters were found to also be appropriate for testing krill oil. They include:
- Trimethylamine (TMA) – A degradation product of choline, responsible for the characteristic ‘fishy’ odor of rotting fish.
- Trimethylamine-oxide (TMAO) – A natural compound found in marine products. Some studies found a correlation between levels of TMAO in blood and the development of cardiovascular diseases.
- Total Volatile basic Nitrogen (TVN) – Includes TMA, ammonia and other basic nitrogenous compounds. It is commonly used as parameter for quality of fish products.
Enzymotec adopted the TMA and TVN quality indices in the manufacturing of its krill oil products and as a standard parameter in its Certificate of Analysis. Low levels of TMA in Enzymotec’s K•REAL® krill oil assures reduced smell and improved freshness of the oil. K·REAL® krill oil’s specifications were approved by third-party laboratories and by ConsumerLab.com® random examination, and were found to be in full compliance with the label claims.
Pure krill oil should be a 100% oily substance. Nonetheless, many krill oils include up to 3% water-soluble compounds, meaning these oils are not truly “pure”. Due to the unique MSO® process, Enzymotec’s K•REAL® krill oil contains less than 0.2% water-soluble impurities, making it the only truly pure krill oil.
Chemical quality parameters, such as TMA, TVN and water-soluble impurities, are indicators of quality during the production and shelf life of krill oil. But what happens when a person consumes krill oil? How can the quality of the oil be monitored as it passes through the digestive system? Enzymotec lipid experts, in collaboration with leading academics in the field, developed a unique in vitro stomach model to test the reactions of krill oil as it passes through the stomach. In the test, krill oils from various manufacturers were compared according to the amount of undamaged omega-3 available for absorption.
Results of the in vitro model reveal great differences in actual omega-3 content available for absorption. K•REAL® krill oil was shown to provide 100% availability, due to the extremely low oxidation. However, other krill oils showed a 10-15% reduction in omega-3 available for absorption, making those oils less potent.
Recently, researchers from Purdue University in Indiana, USA, tested a number of omega-3 supplement brands available on the US market, including krill oil brands. The researchers measured the levels of omega-3 in the supplements, comparing the measured level to the level as stated on the label. Only brands using Enzymotec’s K•REAL® krill oil were found to be true to the label claim, while brands using krill oil of other producers had 20-30% reduction in measured content of their omega-3.
