Kori Pure Antarctic Krill Oil is a source of essential Omega-3 nutrients that support immune, heart, brain, joint, eye and skin health. Kori has superior Omega-3 absorption vs fish oil because it delivers Omega-3s in their most natural phospholipid form, just as you would find in a healthy fish diet. Fish oil loses phospholipids during processing. Kori has no fishy aftertaste because its phospholipids also help it digest more easily than other Omega-3 sources. Plus, Kori is certified sustainably sourced, earning the highest credentials.
