FIELD: pharmaceutical and food processing industry. ^ SUBSTANCE: invention relates to a method for preparing a biologically active substance. Method involves interaction of egg shell powder with the degree of dispersion 0.09 mm, not above, with succinic acid wherein the ratio egg shell powder to succinic acid = 1.8:1. Interaction is carried out in an aqueous medium at temperature 900C for 20 min followed by filtration, evaporation of solution and drying to the constant mass at temperature 1000C. Invention provides preparing mineral complex of relatively constant composition and eliciting enhanced biological value and bioavailability. ^ EFFECT: improved preparing method. ^ 3 tbl, 1 ex |
