A Stable Isotope Study to Evaluate the Bioavailability of an Oat Protein-based Iron Delivery System

In the current study, the OAT fibril - Fe SA (Fe-oat 1) and OAT fibril - Fe NaOH (Fe-oat 2) will both be studied in vivo, alone are oat fibril powder add iron supplement is soluble in water and oat fibril powder add iron supplement is soluble in water in a food matrix (acai puree and honey) to assess their promise as Fe food fortificants. This first in human study to bioavailability assessment and adverse effect of the OAT fibril - Fe SA (Fe-oat 1), OAT fibril - Fe NaOH (Fe-oat 2) and in a food matrix to assess their promise as Fe food fortificants. This study will be conducted with the following objectives. 1. To conduct a stable Fe isotope study to evaluate the bioavailability of OAT-Fe formulated using two reducing agents (Fe-oat 1 and Fe-oat-2) and compared to FeSO4. 2. To compare the performance of Fe-oat 1 and 2 in a food matrix containing Fe inhibitors, (acai puree and honey) in comparison to FeSO4 in a similar meal matrix.
