1. A method for preparing a composition comprising at least one metal-amino acid compound, the method comprising:
carrying out a reaction of a basic compound of a divalent metal with an alpha-amino acid in a molar ratio of 1 to at least 2 in water while heating to 60° C. to 100° C.;
waiting until the reaction has reached an equilibrium, wherein the equilibrium is reached, depending on a nature of the basic compound of the divalent metal, when the basic compound of the divalent metal is dissolved completely in water in the presence of the alpha-amino acid, or when dissolving of the basic metal compound of the divalent metal stalls, or when the basic metal compound of the divalent metal dissolves only to such a degree as fresh basic metal compound of the divalent metal is formed in a reverse reaction;
adding to a reaction solution of the reaction a water-soluble metal salt of the divalent metal in an amount such that a molar total amount of the divalent metal of the basic compound of the divalent metal and of the metal salt of the divalent metal does not exceed a molar amount of the alpha-amino acid;
waiting until the water-soluble metal salt of the divalent metal has completely dissolved in the reaction solution;
drying the reaction solution to obtain the composition as a solid.
