Ocean EFA Antarctic Krill Oil is of the highest grade and is sustainably-sourced from fisheries in the Antarctic through Aker BioMarine, who work with World Wildlife Foundation Norway. This 500mg supplement contains omega 3 fatty acids (DHA and EPA) and phospholipids – good fats that are required for a healthy body and mind. Ocean EFA also contains the powerful antioxidant, astaxanthin. Antioxidants protect our cells from damage by harmful 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 can protect the eye, brain and central nervous system from free radical damage. Unlike fish oil, krill oil does not cause a fishy aftertaste, a common side effect of fish oil. Krill oil is easily absorbed by the body and contains higher amounts of astaxanthin than fish oil. Not intended for use by pregnant or lactating mothers, persons with fish allergy, non fish eaters
