The purpose of this study is to determine the influence of food consumption timing on the body's response to a zinc supplement

Official Title

Evaluation of Zinc Supplementation Taken Prior or With Food


This research is a dietary intervention study designed to evaluate the effect of the food consumption timing on the absorption of zinc supplement.

The main objective is to measure plasma zinc in generally healthy male subjects, who will consume zinc supplement with food or 30-min before food for 2-weeks.

In addition to the primary objectives, correlations in enzyme activity with changes in fat metabolism, namely circulating triglyceride and cholesterol, will be determined. This will enable the determination of the effect of a low Zn intake on various aspects of dyslipidemia.
