NOW Foods Cod Liver Oil 650 mg provides a traditional whole-food omega-3 supplement from the livers of North Atlantic cod — delivering not only EPA and DHA omega-3 fatty acids but also naturally occurring vitamins A and D that are found in cod liver oil but absent from standard fish body oil. This makes cod liver oil a more nutritionally complete supplement than regular fish oil, providing the synergistic combination of omega-3s and fat-soluble vitamins in their natural proportions. Cod liver oil has been used for centuries in Scandinavian and Northern European cultures to prevent rickets, support immune function, and maintain overall health through the low-sunlight winter months. NOW Foods provides 650 mg of cod liver oil per softgel, molecularly distilled for purity and tested for freshness. A nutritionally rich traditional supplement at an accessible price.
