It uses biotin, which affects the metabolism of certain epidermal cells found in the hoof wall; methionine, a building block in the formation of connective tissue; ascorbic acid (vitamin C); copper, which act as catalysts in strong hoof formation; and methylsulfonylmethane (MSM), which helps supply the sulfur necessary for the growth and repair of bones, muscles, and connective tissues. The combination also addresses the needs of horses with founder.
