PRO PAC® Ultimates™ is a fresh approach to nutrition. Made with the highest quality ingredients we can find. (We should know. We source the ingredients ourselves.) We start with real chicken, fish and lamb. We use dietary fats and fibers as well as a variety of wholesome fruits & vegetables. PRO PAC® Ultimates™ is also full of healthy amino acids, vitamins and minerals. Equally important, there’s never corn, wheat or soy fillers in PRO PAC® Ultimates™. There’s also no meat by-products and no artificial colours, flavours or preservatives.
