There are two primary concerns regarding bioavailability of water-soluble vitamins in animal diets and premixes: 1) stability of crystalline vitamins in vitamin and vitaminmineral premixes as well as in diets and supplements; and 2) utilization efficiency of B-vitamin precursors contained in plant- and animal-source feed ingredients. Readers are referred to other reviews for details concerning factors affecting the stability of crystalline vitamins in diets and premixes.
