Krill oil is a supplement made by extracting the oil from the small, shrimp-like animal known as krill, the primary food source of whale sharks and baleen whales. According to WebMD, krill oil is similar to fish oil in that it contains fatty acids that may help decrease swelling, preventing blood clotting and lower cholesterol. It is often used to treat high triglyceride levels, high blood pressure, high cholesterol, heart disease and painful menstruation. It has also been used for depression, cancer, PMS, stroke and osteoarthritis. However, its effectiveness in treating these conditions has not been adequately studied.
Krill oil may interact with anticoagulant and antiplatelet medications that slow blood clotting, including aspirin, ibuprofen, naproxen and others. It may also interact with the weight loss medication orlistat, which prevents the body from absorbing dietary fats. Orlistat may also inhibit the absorption of krill oil, so individuals are encouraged to take the medications at least two hours apart to avoid this effect, according to WebMD.Learn more about Side Effects
