About

Krill oil is oil from a tiny, shrimp-like animal. Baleen whales, mantas, and whale sharks eat primarily krill. In Norwegian, the word "krill" means "whale food." People extract the oil from krill, place it in capsules, and use it for medicine. Some brand name krill oil products indicate that they use Antarctic krill. This usually refers to the species of krill called Euphausia superba.

Krill oil is used for heart disease, high levels of certain blood fats (triglycerides), high cholesterol, high blood pressure, stroke, cancer, osteoarthritis, depression, premenstrual syndrome (PMS), and painful menstrual periods.

How it works

Krill oil contains fatty acids similar to fish oil. These fats are thought to be beneficial fats that decrease swelling, lower cholesterol, and make blood platelets less sticky. When blood platelets are less sticky they are less likely to form clots.

Effectiveness

Not Proven
High cholesterol

Developing research shows that taking 1-1.5 grams of a specific krill oil product (Neptune Krill Oil, Neptune Technologies & Bioresources, Inc) daily reduces total cholesterol and “bad” low-density lipoprotein (LDL) cholesterol, and increases “good” high-density lipoprotein (HDL) cholesterol in patients with high cholesterol. Higher doses of 2-3 grams daily also appear to significantly reduce levels of triglyceride, another type of blood fat.

Osteoarthritis

Early research shows that taking 300 mg of a specific krill oil product daily reduces pain and stiffness in people with osteoarthritis.

Premenstrual syndrome (PMS)

Early research shows that taking a specific krill oil product might reduce PMS symptoms.

Rheumatoid arthritis

Early research shows that taking 300 mg of a specific krill oil product daily reduces pain and stiffness in people with rheumatoid arthritis.

Concerns

Possibly safe

Krill oil is POSSIBLY SAFE for most adults when used appropriately for a short amount of time (up to three months). Research on krill oil has not adequately evaluated its safety or possible side effects. However, it is likely that krill oil can cause some side effects similar to fish oil such as bad breath, heartburn, fishy taste, upset stomach, nausea, and loose stools.

18/Warnings

Warnings

Pregnancy and breast-feeding: Not enough is known about the use of krill oil duringpregnancyandbreast-feeding. Stay on the safe side and avoid use.Are there any interactions with medications?

Seafood allergy: Some people who are allergic to seafood might also be allergic to krill oil supplements. There is no reliable information showing how likely people with seafood allergy are to have an allergic reaction to krill oil; however, until more is known, avoid using krill oil or use it cautiously if you have a seafood allergy.

Surgery: Because krill oil can slow blood clotting, there is concern that it might increase the risk of bleeding during and after surgery. Stop using krill oil at least 2 weeks before a scheduled surgery.

Interactions

Always consult with your doctor.
Minor
Orlistat (Xenical, Alli)

Krill oil might lower blood sugar. Diabetes medications are also used to lower blood sugar. Taking krill oil along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.Krill oil might slow blood clotting. Taking krill oil along with medications that also slow clotting might increase the chances of bruising and bleeding.Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.Orlistat (Xenical, Alli) is used for weight loss. It prevents dietary fats from being absorbed from the gut. There is some concern that orlistat (Xenical, Alli) might also decrease absorption of krill oil when they are taken together. To avoid this potential interaction take orlistat (Xenical, Alli) and krill oil at least 2 hours apart.
