Abstract

There are many forms of mineral supplements currently available. Among these mineral-enriched gluconates and yeast are considered two of the more biologically available supplements. The purpose of this study was to use zinc (Zn)- or copper (Cu)-deficient rats to determine whether the organically bound mineral in yeast or the salt gluconate form was more bioavailable, i.e., is absorbed and found in a greater concentration in liver. It was demonstrated that Zn-enriched yeast was 3.7 times more bioavailable than the Zn gluconate and that Cu-enriched yeast was 1.4 times more bioavailable than the Cu gluconate.
