NCT05642689

Brief Summary

The primary objective was:

  • to compare iron absorption in apparently healthy children aged 3-6y from an instant full cream milk drink fortified with ferric pyrophosphate or ferric ammonium phosphate relative to ferrous sulfate as the reference fortificant.
  • To compare iron absorption from ferric pyrophosphate to ferric ammonium phosphate from the milk drink

Outcome Measures

Primary Outcomes (1)

  • Determination of iron absorption from FAP and from ferric pyrophosphate relative to Ferrous sulfate

    It is based on calculated amount of 58Fe and 57Fe appearing in the blood. For that the shift of the iron isotope ratios in the blood samples collected 14 days after the last consumption of the last test drink are measured. The calculation of circulating iron is based on blood volume and hemoglobin concentration. For calculations of fractional absorption, 90% incorporation of the absorbed iron into red blood cells is assumed. The relative iron absorption from FAP and from ferric pyrophosphate relative to ferrous sulfate is then calculated as follows: Relative bioavailability of a salt (RBV %) = ( Fe absorption from an iron salt/ Fe absorption from ferrous sulfate)∗ 100. The comparison of the iron absorption from ferric pyrophosphate to that from ferric ammonium phosphate will be made by statistical analysis of data measured and calculated as described above.

OTHER

Comparison of iron absorption from FAP to Ferrous sulfate in milk

Other: Iron fortified milk with iron salt labelled with 58Fe and 57Fe

OTHER

Comparison of iron absorption from ferric pyrophosphate to Ferrous sulfate in milk

Other: Iron fortified milk with iron salt labelled with 58Fe and 57Fe

Interventions

Oral administration of a serving of iron labelled with stable isotope (2 mg Fe per serving) in 200ml of reconstituted milk once after a overnight fast. The alternate test drink was fed on the following day in the same fashion. The administration was repeated on day 3 and 4.

Also known as: Iron fortified milk with ferrous ammonium posphate labelled with 57Fe, Iron fortified milk with ferrous sulfate labelled with 58Fe
