Krill oil is used for high cholesterol, osteoarthritis, premenstrual syndrome, rheumatoid arthritis and high blood pressure, as reported by WebMD. Other conditions krill oil is used for include stroke, cancer and depression. Insufficient evidence exists for the use of krill oil in these conditions, however.
Developing research shows that taking 1-1.5 grams of krill oil daily reduces total cholesterol and bad cholesterol and increases good cholesterol, according to WebMD. Higher doses of 2-3 grams daily appear to reduce triglyceride levels as well.
Taking 300 milligrams of a specific krill oil product daily has been shown to reduce the pain and stiffness associated with osteoarthritis and rheumatoid arthritis, states WebMD. Early research also shows that taking a specific krill oil product reduces symptoms of premenstrual syndrome.
Krill oil is derived from tiny sea animals called krill, states WebMD. Oil extracted from krill is put in capsules and used as medicine. The fatty acids in krill are similar to those in fish oil and are thought to have the ability to decrease swelling, make platelets in blood less sticky and lower cholesterol. People with a seafood allergy as well as those who are pregnant or breast-feeding should avoid taking krill oil. Krill oil should be stopped two weeks before surgical procedures so as not to increase the risk of bleeding.
