ProPath? Fe 150 (iron amino acid complex) is a nutritional feed ingredient for all species that contains 15 % organic iron. It is built from a unique, patented trace mineral product that combines two specific amino acids, each bound (or complexed) to a separate iron ion, in a stable, 1:1 ratio. Flexible for use in a wide variety of diets, such as conventional or specialty (like non-GMO), ProPath Fe 150 relies on two synergistic, amino-acid absorption pathways (cationic and anionic) to elevate iron mineral nutrition in the animal. Optimizing these pathways allows iron to be more effectively absorbed and metabolically available in the animal?s organs, tissues and enzyme systems. Zinpro Performance Minerals provide the highest biological efficacy of any trace mineral products on the market. For more than 45 years, Zinpro Performance Minerals have delivered positive animal performance responses and a strong return on investment in operations around the world
