Krill oil is extracted from krill (Euphausia superba) which is a shrimp-like marine animal. It is a rich source of n-3 PUFAs, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and types of omega-3 fats found exclusively in marine sources. The fatty acids present in krill oil are incorporated into phospholipids which are easier for the body to absorb. Krill oil supports cardiovascular health and a healthy cholesterol level by managing the level of HDL “good” cholesterol in the body. It also supports joint health, aids in pain management, and has no fishy aftertaste. Krill oil is most commonly taken by mouth for heart disease, high levels of certain blood fats (triglycerides), and high cholesterol, but there is limited scientific research to support these uses. It is also used for dry eyes.
