What is krill oil?

Krill are shrimp-like crustaceans that account for the world's largest single-species animal biomass. A Canadian company, Neptune Technologies, has the patent for the extraction of oil from krill. Like fish oil, krill oil is a rich source of omega-3 unsaturated fatty acids, particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), but there is a major difference between fish oil and krill oil: in fish oil, DHA and EPA are present in triglycerides, whereas in krill oil they are present in phospholipids.

So what? Well, the fact is that phospholipids are what cell membranes are made of. This means that the super-beneficial omega-3 fatty acids in krill oil are more easily absorbed - VERY easily absorbed, in fact: some research has shown that krill oil supplements can have positive effects on the brain within TWO HOURS of being taken!
