KRILL OIL: Benefits, Side Effects, Uses, Dosage, Warnings?
The krill is the generic name (a Norwegian) small one shrimp in cold water, the order of euphausiids (Euphosiacea, sometimes called Euphosiaceae). Krill is an important link in the food web in the oceans.
Are grouped under the term of at least 85 species whose adults live in "swarms" giant in the upper layers of the ocean, eggs and larvae are found to over 1000 m deep. Swarms sometimes form schools of two million tonnes spanning 450 km ².
With estimates of approximately 650 million tonnes, krill are among the most abundant animal groups on the planet, after the copepods .

Distribution [ change | change the code ]
Arctic and the northern Atlantic Ocean , it is mainly Meganyctiphanes norvegica , crustaceans 6 cm to 7 cm long and weighing an average of 2 g , the almost transparent and slightly greenish body as it feeds by filtering phytoplankton , pigmented red dots showing two large black eyes. He lives up to six years.
In the Southern Ocean , krill mainly consists' of Euphausia superba and no dorsal curvature and having large black eyes. Pelagic, it is the first power source baleen whales ( baleen , including large whales and right whales ), with a very low yield for cetaceans, as to grow to 1 kg , they must absorb 100 kg . Whales eat several tons per day. Thus, the movement of these tiny crustaceans he drives alone, the migration of sea giants.
Krill is at the center of a major food chain, on which squid, marine mammals, birds, fish and some whales that feed.
Krill and other types of shrimp are responsible for the pink color of flamingos and pink-orange flesh of wild salmon. It in effect contains the astaxanthin , a carotenoid red, a vitamin antioxidant.
It is the subject of an industrial fishing, which in Norway and around Antarctica.
Ecology [ change | change the code ]
It contributes to the bioconcentration of toxic in the food chain , particularly mercury and other pollutants , however it contains proportionately much less than the "top" predators (large fish ( tuna , marlin , swordfish and ... carnivorous mammals, such as dolphins , orca or whale )).
Krill is the subject of an industrial fishery that supplies mainly the market for animal feed flour (or freeze-dried krill), Fishing whose impacts are not finely measured.
It is possible that the amounts of krill have locally increased significantly xix th and xx th century , following the significant decline in the number of large cetaceans , and overfishing of fish ( fishing ?) that fed while waters warmed and lost their salinity , perhaps because of the beginnings of a global warming importantly, while receiving more and more nitrate and phosphate s anthropogenic; very favorable to the population explosion conditions phytoplankton that are the staple diet of krill. This appears to lead to very significant changes in the composition and location of oceanic species. Some authors believe that the krill population has declined by about 80% due to global warming, endangering several species.
Krill is also an important filtering of the oceans, which reduces turbidity .
The krill movement and migration nocturnal / diurnal or seasonal likely to be significant, like other species of zooplankton in terms of mixing of thermal and / or more or less salt in areas where he lives layers.
Who would think that a small crustacean cold seas would conceal itself as much therapeutic! This small shrimp called krill, plankton considered a cold sea, is surely the most popular menu largest marine animal of our time, the whale that consumes many tons per day ...
"Krill oil: oil with amazing healing powers" - Photo credit: © Professor Uwe Kils | fr.wikipedia.org The enthusiasm of researchers for krill is that the extracted oil has a fatty acid content of omega 3, 6 and 9, which makes it as effective as fish oil, if not more. It has been shown through scientific studies that krill oil was eight to ten times more effective than fish oil to lower blood cholesterol and increase the good cholesterol (HDL). The researchers also found that krill oil lowered blood glucose levels by 6% against only 3% fish oil.
Another important aspect while oily fish often suffer from a high degree of heavy metal pollution, krill, meanwhile, is less affected because it is at the top of the food chain.
A powerful antioxidant
Krill oil contains one of the most powerful antioxidants consist of a complex marine bioflavonoids and astaxanthin.
Bioflavonoids struggling against depressive syndromes and disorders of memory. Astaxanthin, meanwhile, chemically similar to beta carotene found in carrots or vitamin A, is a powerful antioxidant that fights against free radicals and can be up to 50 times more effective than vitamin E or beta carotene. It also exert anti-inflammatory and stimulates the immune system.
One of the most interesting properties of astaxanthin is its role in the protection and repair of retinal damage and macular degeneration.
It is rich in essential fatty acids and also contains phospholipids that transport of antioxidants in the cell membrane by preventing the intracellular penetration of viruses and ensuring effective protection against viral infection.
A cocktail of vitamins
Krill oil also contains many B vitamins as well as vitamins E and D. It is rich in iron, iodine, copper, manganese, chromium, selenium and zinc, as well as minerals.
Oil for Women
In a study conducted at the University of Montreal, scientists were able to show that krill oil has soothing properties and reduce the effects of PMS and menstrual pain.
How is the oil extraction?
Difficult to extract oil, krill easily loses its antioxidant power. After much research by Japanese and Scandinavians is to Canadians from the University of Sherbrooke that returns the palm. They finally managed to stabilize it. This is a Quebec company that has exclusivity and markets under the brand of Neptune Krill Oil. This brand is imported for some years in France and is available at specialty stores 500 mg capsules.
