To develop the new use of MgCl2.6H2O and H3PO4 and contribute to the health maintenance of living body under the concept that there is no research for the physiological action of struvite (MgNH4PO4.6H2O) known as an important reagent for chemical analysis, struvite is scarcely soluble in water but soluble in gastric acid (hydrochloric acid) to form MgCl2.6H2O, H3PO4 and NH4Cl which are known substances and the taking of MgCl2.6H2O and H3PO4 is supposed to cause direct physiological actions by the bioregulation function as mineral electrolytes in vivo, participate in various unknown bioreactions and improve various bioactivation function and bioprotecting function.

Struvite is dissolved in hydrochloric acid or various other acids and the dissolution products are analyzed to develop beneficial uses of the substances.
