This Daily Dose Equine Amino Essentials Horse Supplement provides a full spectrum of all equine essential amino acids, i.e. those which a horse cannot manufacture itself and which must be derived from the diet. Critical body processes depend on these amino acids, and, if unavailable, can impede normal growth and development. Muscles, bones, hooves and the entire immune system itself rely on a steady, available supply of these nutrients. Use this horse supplement with horses of all life stages.
