Cod Liver Oil Extra ™ from SUPERFOODS™ is a nutritional supplement derived from the liver of the cod fish. Cod lives deep in the Baltic Sea and the Northern Seas of the Arctic. Until 1975 Cod was fished at the Delta of the Evros River in large quantities and produced the well know black caviar. Cod Liver Oil is extremely beneficial to the health as it is a natural source of vitamins and an exceptional source of the Omega 3. Cod Liver Oil contains the Omega 3 polyunsaturated fatty acids (ÅÑÁ & DHA) while it contains the Vitamins A, D, and E Å, which all combined contribute to better health.
