What is Krill Oil?


Krill oil is an oil derived from krill, shrimp—like crustaceans. Krill (Euphausia superba) are found in the colder waters of the ocean. Primarily, they serve as a food source for other animals found in the ocean such as whales, penguins, seals, squid and fish. Two of the most important components present in the krill oil are omega-3 fatty acids similar to fish oil, mainly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Omega-3 are the fatty acids, a type of unsaturated fatty acid, that play an important role in brain and nerve functioning. Omega-3 fatty acids are also known as “essential fatty acid”. Its because human body can’t produce them and they can be obtained only from food.

There are three main types of omega-3 fatty acids —

  • Eicosapentaenoic acid (EPA)
  • Docosahexaenoic acid (DHA)
  • Alpha-linolenic acid (ALA)

Krill oil is used for heart ailments, dry eye disease, high levels of cholesterol in the blood (hyperlipidemia) and high levels of fats called triglycerides in the blood (hypertriglyceridemia). (SEE ALSO: Omega-3 Foods : 10 Best Source of Omega-3 Fatty Acids)

This oil has also been used to treat high blood pressure (hypertension), stroke, cancer, osteoarthritis, depression and premenstrual syndrome (PMS). However, more research are needed to support these benefits. Here, patients are advised to speak with their doctor or health care provider prior to using krill oil for any condition.
