Kepler's Cod Liver Oil with Malt Extract

Cod liver oil is a dietary supplement derived from liver of cod fish (Gadidae).[1] As with most fish oils, it contains the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and also vitamin A and vitamin D. Historically, it was given to children[where?] because vitamin D had been shown to prevent rickets, a consequence of vitamin D deficiency.[2]
