Zinc Glycinate – Pharmacokinetic (pK) Study
Bioavailability Study
Zinc is an essential mineral that is involved in many aspects of cellular metabolism.* Zinc is a key cofactor in hundreds of enzymatic reactions and plays a critical role in protein synthesis, the maintenance of cellular structures, and cell signaling.* Because of these varied functions, zinc is necessary for the maintenance of skeletal, neurological, reproductive, and immune system health.*
Results
The average concentration of serum zinc increased gradually over the course of the study, beginning with the 2-hour measurement, which was 43% above the baseline level. Four hours after supplementation, the average concentration of zinc reached a peak 57% above the baseline concentration. The study confirms the exceptional bioavailability of dietary supplement Zinc Glycinate from NOW®.
