NCT03895424

Brief Summary

The study aims at assessing the iron (Fe) bioavailability from a newly developed iron compound - an iron fatty acid complex. The iron from the compound is hypothesized to have a higher absorption rate than commonly available supplements in the market. The study is a cross over, human iron isotope study with three arms where participants consume the experimental dietary products in a randomized fashion. The study duration is of 45 days - from the day of the capsule administration till the last blood sampling point

Outcome Measures

Primary Outcomes (15)

  • Fractional iron absorption from IFAC

    The primary outcome is the fractional iron absorption, which will be compared in predefined comparisons from the three different capsules that will be administered to the study participants. Relative bioavailability, defined as the ratio of fractional absorption relative to the reference dose (absorption measured from encapsulated FeSO4), will be also compared in predefined comparisons.

    Day 10 of the study
