Krill are shrimp-like crustaceans that are approximately 1 to 6 centimeters long. They live is the ocean, where they feed mainly on phytoplankton. Krill live near the bottom of the food chain and are eaten by whales, seals, penguins, squid and fish. Krill primarily live in the Southern Ocean and the northern Pacific Ocean along the coasts of Canada and Japan. Krill used for aquaculture and aquarium feeds, sport fishing bait or they are eaten as a source of healthy fatty acids. Krill oil is made from a species of krill Euphosia superba. Krill oil consists of three components: (1) omega-3 fatty acids similar to those of fish oil (2) omega-3 fatty acids attached (conjugated) to phospholipids, mainly phosphatidylcholine (alternatively referred to as marine lecithin) and (3) astaxanthin, an antioxidant. The algae that krill eat produces the bright red pigment astaxanthin that gives krill and other crustaceans such as lobster and shrimp their reddish-pink color. Advantages of ASTAXANTHIN: Protection against cardiovascular diseases. Astaxanthin is capable of penetrating the blood-brain barrier, therefore stretching its antioxidant action to the brain. Stimulates the immune system. Antioxidants protect our body cells from damage from free radicals, unstable substances that are thought to contribute to certain chronic diseases. Unlike many other antioxidants, astaxanthin crosses the blood brain barrier, where it could possibly protect the eye, brain and central nervous system from free radical damage.

Krill Oil vs Fish Oil
Unlike fish oil, krill oil doesn’t cause fishy burps or an aftertaste, a common side effect of fish oil. Also, krill oil contains higher amounts of astaxanthin than fish oil. Here are some specific conditions for which it’s used.
Krill Oil 48x more potent then Fish Oil
Krill oil contains vitamin E, vitamin A, vitamin D and canthaxanthin, which is – like astaxanthin – a potent anti-oxidant. The anti-oxidant potency of krill oil is such that when compared to fish oil in terms of ORAC (Oxygen Radical Absorptance Capacity) values, it was found to be 48 times more potent than fish oil.
Health benefits of Krill Oil:
Cholesterol: Krill oil is being studied as a natural remedy for high cholesterol. In one study, 120 people were given krill oil, fish oil or a placebo. Krill oil reduced LDL (commonly referred to as “bad”) cholesterol by 34% and increased HDL (“good”) cholesterol by 43.5% compared to the placebo. In comparison, fish oil reduced LDL cholesterol by 4.6% and increased HDL cholesterol by 4.2%. Krill also lowered triglycerides.
Premenstrual syndrome: Preliminary research suggests krill oil may help reduce symptoms of premenstrual syndrome (PMS), however, more research is needed.
Arthritis: A study in the Journal of the American College of Nutrition examined krill oil (300 mg daily) compared to a placebo and found that krill oil was effective at reducing arthritis symptoms and inflammation.
