Every horse owner has heard the expression "no hoof, no horse." A horse's hooves play a crucial role in its ability to survive and function, and caring for them requires more than just scheduling regular visits with the farrier. Nutrition is vital to hoof condition, as a horse's hooves contain over 90% protein. The protein keratin is a significant component of hooves and hair. Cysteine, the primary amino acid in keratin, is derived from methionine and other sulfur-containing compounds, such as biotin. Vital to the development of connective tissue, biotin plays an essential role in the health of a horse's muscles, skin, hair, and hooves. Biotin is necessary for protein metabolism and contributes sulfur for proper keratin formation of the hoof wall. Vita Biotin Crumbles supports good hoof health in horses.
