Krill oil is an extract prepared from a species of Antarctic krill, Euphausia superba.

Processed krill oil is commonly sold as a dietary supplement.

Two components of krill oil are omega-3 fatty acids similar to those in fish oil, and phospholipid-derived fatty acids (PLFA), mainly phosphatidylcholine (alternatively referred to as marine lecithin).

Krill oil is an oil extracted from krill, which are small, shrimp-like marine crustaceans.

Krill are a primary food source for many marine animals, and they are found in abundance in the Southern Ocean around Antarctica.

The oil extracted from krill is known for its high concentration of omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

These omega-3 fatty acids are considered beneficial for human health and are commonly found in fish oil.

In addition to omega-3 fatty acids, krill oil contains other compounds such as astaxanthin, a carotenoid with antioxidant properties.

The presence of astaxanthin gives krill oil its reddish color.

Krill oil is marketed as a dietary supplement, often promoted for Krill oil potential health benefits, including supporting cardiovascular health, reducing inflammation, and providing essential fatty acids.

Some people choose krill oil as an alternative to fish oil supplements due to potential differences in absorption and the additional presence of astaxanthin.

Krill oil, derived from tiny marine crustaceans known as krill, is a rich and complex substance boasting an array of nutritional components.

Krill oil is characterized by its vibrant reddish hue, a result of the presence of the powerful antioxidant astaxanthin.

Extracted from the Southern Ocean, krill oil is renowned for its high concentration of omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

The unique composition of krill oil includes essential phospholipids, providing a distinctive structure that may enhance absorption compared to traditional fish oil.

Known for Krill oil superior bioavailability, krill oil is often favored by individuals seeking an omega-3 supplement.

The omega-3 content in krill oil contributes to its potential cardiovascular benefits, supporting heart health and promoting healthy lipid profiles.

Additionally, krill oil's phospholipid-bound omega-3s may aid in cellular membrane integrity and function.

Astaxanthin, a carotenoid present in krill oil, not only adds a reddish tint but also serves as a potent antioxidant, shielding the oil from oxidative damage.

This antioxidant prowess may extend benefits to consumers, protecting cells from free radicals.

Krill oil comes from a tiny, shrimp-like marine animal.

It's rich in the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

The benefits of krill oil seem to come from Krill oil omega-3 fatty acid content.

The body doesn't produce many of Krill oil own omega-3 fatty acids.

Omega-3 fatty acids can reduce pain and swelling and also prevent the blood from clotting easily.

People use krill oil for dry eye.

Krill oil is also used for high levels of triglycerides in the blood, high cholesterol, diabetes, depression, and many other conditions, but there is no good scientific evidence to support many of these uses.

Don't confused krill oil with algal oil, cod liver oil, fish oil, or shark liver oil.

These are not the same.

Krill oil is derived from tiny crustaceans called Antarctic krill.

These sea creatures are a dietary staple for many animals, including whales, seals, penguins and other birds.

Like fish oil, krill oil is rich in EPA and DHA, the two types of omega-3 fatty acids that provide most of Krill oil health benefits.

However, the fatty acids in krill oil are structurally different than those in fish oil, and this may impact the way the body uses them.

Krill oil also looks different than fish oil.

While fish oil is typically a shade of yellow, a naturally occurring antioxidant called astaxanthin gives krill oil a reddish color.

Krill is a small crustacean with an appearance similar to shrimp.

They are found in the colder waters of the ocean.

Krill primarily serve as a food source for other animals in the ocean, for example - whales, seals, penguins, squid and fish.

Krill is found in the oceans off of Antarctica, Canada, and Japan. 

Harvesting of krill is controversial.

There is concern that commercial harvesting of Krill for use in Krill Oil supplements could threaten the species that consume Krill oil for food, including whales.

All krill oil sold in nutritional supplements is harvested out of the open ocean, upsetting the natural balance of food supplies for larger marine animals.

Commercial uses of Krill include salmon aquaculture farming, harvesting for use in Krill Oil capsules, as food for home aquariums, and as a human food source.

Krill, known as Okiami has been harvested by the Japanese as a human food source since the 19th century, and is also consumed in South Korea and Taiwan.

Krill has a pink or red appearance due to the plankton that they consume as a food source in the ocean.

Krill contains an oil that is similar to the oils found in fish oils, the omega-3 fatty acids.

Omega-3 fatty acids are recommended for use in lowering triglyceride levels.

Krill Oil use as a supplement to lower blood lipids is increasing in popularity.

Krill Oil contains:

The omega-3 polyunsaturated fatty acids EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic).

Omega-3 polyunsaturated fatty acids are also found in oils from certain types of fish, vegetables, and other plant sources.

Unlike fish oil, the omega-3 fatty acids in Krill oil are absorbed and carried to the body's cells in phospholipid form.

Omega-3 fatty acids, in combination with diet and exercise, work by lowering the body's production of “bad”, low density lipoprotein (LDL) and triglycerides, and may raise high density lipoprotein (HDL) “good”  cholesterol.

High levels of cholesterol and triglycerides can lead to coronary artery disease, heart disease, and stroke.

Supportive, but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease.

Krill Oil also contains:

Phospholipid-derived fatty acids (PLFA), which may result in better absorption, and marine lethicin.

A carotenoid antioxidant called astaxanthin.

Antioxidants inhibit oxidation and may neutralize the oxidant effect of free radicals and other substances in body tissues that may lead to disease.

Krill Oil has also been used to treat high blood pressure, stroke, cancer, osteoarthritis, depression and premenstrual syndrome (PMS), although high quality studies with adequately sized populations validating these uses are lacking.

Patients should speak with their physician prior to using Krill Oil for any condition.

Warnings issued by the FDA note that certain fish (marlin, tuna, swordfish) may contain toxins such as methylmercury, leading some consumers to be wary of eating fish to obtain omega-3 fatty acids. 

Manufacturers of Krill Oil suggest it may be safer due to lower levels of contaminants such as mercury.

The FDA has issued recommendations that women who are pregnant or planning to become pregnant, and young children avoid eating more than 6 ounces of fish per week.

However, Krill may also contain methylmercury and other pollutants from sea water, although they are lower on the food chain and may contain lower values of such pollutants.

One study noted that Krill harvested from Antarctica contains high levels of organic pesticides.

Manufacturers of Krill Oil claim one of the advantages of Krill Oil over Fish Oil is that it does not lead to the fishy aftertaste, reflux or belching of fish flavors, a common side effect with fish oil supplements. However, Krill Oil may still lead to these side effects in some patients.

The U.S. Food and Drug Administration (FDA) has not specifically made recommendations on Krill Oil safety or effectiveness.

Krill Oil is considered a dietary supplement and does not require a prescription.

Krill Oil may also be used for purposes not listed in this medication guide.

Difference between krill oil and fish oil:

Krill oil and oceanic fish oil are rich in omega-3 fatty acids, mainly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

While both contain some EPA and DHA as free fatty acids, krill oil contains particularly rich amounts of choline-containing phospholipids and a phosphatidylcholine concentration of 34 grams per 100 grams of oil.

Krill oil also contains appreciable content of astaxanthin at 0.1 to 1.5 mg/ml, depending on processing methods, which is responsible for Krill oil red color.
