Vitamin A is involved in the process of formation and preservation of function of epithelial tissues and
mucous membranes, is important for fertility and is essential for vision. Vitamin D3 regulates and corrects
calcium and phosphate metabolism in blood and plays an important role in the uptake of calcium and
phosphate from the intestines. Especially in young, growing animals vitamin D3 is essential for the
normal development of skeleton and teeth. Vitamin E is, as a fat-soluble intracellular antioxidant, involved
in stabilising unsaturated fatty acids, thereby preventing toxic lipo-peroxides formation. Furthermore,
vitamin E protects the oxygen-sensitive vitamin A from oxidative destruction in this preparation.
