Comparison of the Oral Absorption, Distribution, Excretion, and Bioavailability of Zinc Sulfate, Zinc Gluconate, and Zinc‐Enriched Yeast in Rats

After zinc sulfate (ZnS), zinc gluconate (ZnG), and zinc‐enriched yeast (ZnY) are orally administered to rats, plasma, tissues, urine, and feces at different time points are collected for the quantification of zinc concentration. The oral absorption, distribution, excretion, and bioavailability of ZnS, ZnG, and ZnY are compared.
