This has the advantage that the magnesium is protected (by the "coat" of amino acids) and this allows it to reach the small intestine almost intact for better absorption. In addition, Vitamin B6 is added, which contributes to normal energy metabolism and the reduction of tiredness and fatigue. Taurine was added for a synergistic effect. - Magnesium amino acid in chelated form for better absorption - With vitamin B6 that contributes to a normal energy metabolism and to the reduction of tiredness and fatigue - Contains taurine for a synergistic effect .
