Biotin

This sulfur-containing vitamin is especially important for the maintenance of hooves, and significant for the health of all connective tissue structures. It stimulates keratin production in the hoof, hoof wall, sole and frog, with an added benefit of improvement of the horse’s general appearance and luster. Horses with poor quality hooves may benefit from supplementation at 25 mg daily; higher doses are suggested for horses receiving little or no grain. Beneficial for hooves that are shelly and brittle.
