Iron Bioavailability of High Surface Area Ferric Phosphate (HiFe)

September 10, 2021 updated by: Prof. Michael B. Zimmermann, Swiss Federal Institute of Technology

Iron Bioavailability of High Surface Area Ferric Phosphate in Thai Women

The primary objective of this study is to compare iron absorption of high surface area ferric phosphate with that of ferrous sulfate and bulk ferric phosphate in a rice-based meal in non-pregnant women.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Fractional iron absorption
Time Frame: Measured 14 days after consumption of the 4 different types of iron vehicles (Days 16 and 31)
Iron absorption will be determined by measurement of the isotopic ratio change from the 4 different types of iron vehicles (FeSO4 fortified rice test meal, FePO4 fortified rice test meal, HiFePO4 1 fortified rice test meal, HiFePO4 2 fortified rice test meal).
Measured 14 days after consumption of the 4 different types of iron vehicles (Days 16 and 31)
