Supercritical Fluid Extraction involves using CO2 as a medium to extract the omega-3 fatty acids and separate them from other parts of the oil, such as free fatty acids and cholesterol. This not only protects the oils from oxidation, but also protects the oil from contamination with microorganisms that can’t survive without oxygen.
Unlike other extraction methods, no chemical solvents, cholesterol, or other undesirable compounds are found in the finished oil and there is no need for chemical preservatives. CogniDHA Supercritical CO2 oils have some of the lowest levels of contaminants physically possible.
Selecting the right quality and species of fish is one of the factors leading to the exceptional purity of CogniDHA Fish Oil. Anchovies, sardines and mackerel caught off the coast of South America, are rich in oil yet low on the food chain, which means less exposure to environmental toxins and less contaminants. CogniDHA Fish Oil is encapsulated in fish gelatin from Tilapia, eliminating all bovine or porcine by-products.
