Ultra Red Krill Oil provides 500mg of pure Krill oil, a special source of Omega-3 with a high concentration of marine phospholipids so may be better utilised in the body than standard Omega-3 found in fish oil. Ultra Red Krill Oil provides essential fatty acids for the normal function of the heart, brain and vision all within an easier to swallow smaller capsule with no unpleasant fishy odour, taste or aftertaste. As well as Omega-9 fatty acids, Ultra Red Krill provides Omega-3, a rich source of the essential fatty acids DHA (Docosahexaenoic Acid) and EPA (Eicosapentaenoic Acid). EPA and DHA are classed as essential fatty acids because they cannot be made efficiently by the body and must be obtained through the diet. - DHA contributes to the maintenance of normal vision and brain function1 - DHA and EPA contribute to the normal function of the heart2 Important: Ultra Red Krill contains only pure Krill oil, rather than Krill oil combined with ordinary fish oil as found in some products.
