Details and patient eligibility

About

The purpose of this study is to determine the effects of consuming a small breakfast of juice and toast with added phytate or with taking a folic acid supplement on the absorption of a small amount of zinc that is either bound to amino acids or to chloride or picolinate. The results of this study will provide new information on how components of diet (e.g., phytate, and folic acid) affect the absorption of different forms of dietary zinc (e.g., zinc bound to amino acids, zinc chloride, and zinc picolinate).
