No! Never! Because our food is raw, high in meat and made with whole animal (including organs and bone), we don't need to add synthetic vitamins to make up for what has been cooked off (or was never there to begin). We add fresh fruit & vegetables to provide the remainder of fiber, vitamins and minerals, as well as trace amounts of copper, zinc, iron, and manganese as amino acid complexes, to make it easy for a pup's stomach to absorb our nutrient-rich food creating a perfectly balanced meal that meets AAFCO guidelines. Again - the only ingredients in our food are meat (inc. organs and bones), fruits & vegetables. That's it!
