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. While more research is needed on the potential benefits of using this oil as a treatment for certain medical conditions, patients interested in taking this supplement can consult their physician about whether krill oil might be useful for their individual health needs. When taking a krill oil capsule, the capsule must be swallowed whole; puncturing the capsule is not recommended. Patients who are pregnant may need to avoid krill oil during their pregnancy due to its mercury content. In addition, individuals having surgery will need to stop taking these supplements at least two weeks before their operation. Krill oil should not be taken by patients who are using blood thinners.
