Benefits Krill Oil Provides Health

Krill are small crustaceans similar to shrimp, and they are a major food source for whales, penguins, seals, and fish. Krill oil is typically extracted from a species of Antarctic krill, and it is sold as a dietary supplement, mostly in capsule form. Like fish oil, krill oil is a highly concentrated source of omega-3 fatty acids. The oil contains other fatty acids derived from phospholipids, and it is a good source of astaxanthin, a type of carotenoid. Patients have used krill oil to help with conditions such as high blood pressure, premenstrual syndrome, osteoarthritis, and depression.
