The word chelate by definition means to combine with a metal (mineral). It is the bonding between a mineral and an organic molecule. The organic molecule aids in the absorption of the mineral while it also protects the mineral from being prematurely broken down, therefore making Chelated minerals more stable. Chelated minerals or as sometimes described, organic minerals are minerals bound to small proteins (peptides) or amino acids. These small proteins are readily absorbed into the horses body during digestion, resulting in better availability to the horse than typical inorganic mineral sources.
