Krill oil is an extract of Antarctic crustacean species Euphausia superba and is rich in numerous nutrients that are beneficial to human health including Omega-3 Fatty Acids These are some of the most heavily researched nutrients in the world.
Researchers discovered in the 1970s that Greenland Inuit tribes, who ate copious amounts of fish and blubber (no greens whatsoever), had very little incidence of cardiovascular disease. This led to more than 4,500 studies so far on the effects of omega-3s on human health.
Phospholipids The omega-3s in krill oil are bound to phospholipids, the very thing from which human cell walls are composed. The omega-3s in fish oil, in contrast, come in the form of triglycerides, which must be broken down into their components before being absorbed by the body.
Astaxanthin This is one of the most powerful anti-oxidants we know. It is produced by the phytoplankton that grows on sea ice, and which is the main food source for krill. It is red in color, and is what gives many creatures of the sea their reddish hue. Krill meal is a main source of food for fish farms. Most commercially farmed salmon would not have its pinkish color except for having been fed on krill meal.
Choline This is another essential element in the human diet, responsible for transporting important lipids (essential fats), protecting the liver from fat accumulation and transporting nerve impulses. It is necessary for the development of memory, and may be important to combat depression and anxiety.
