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^®.
