Platinum Hoof Support was designed to support healthy hoof strength and growth in horses with advanced hoof care needs by providing concentrated levels of highly bio-available Biotin, as well as trace minerals Zinc, Manganese, Copper, Cobalt, and important amino acids L-Lysine and Methionine. Platinum Hoof Support should be used in conjunction with one of these three formulas for best results: Platinum Performance® Equine, Platinum Performance® CJ, or Platinum Performance® GI.
