This systematic review indicates that iron supplementation increases  Hb levels in children significantly but modestly .
The increase is greater in subjects who are anaemic at the start of the trial and lower in malarial hyperendemic areas and in those consuming iron-fortified food .
OBJECTIVE To evaluate the effect of iron supplementation on  haemoglobin ( Hb ) in children through a systematic review of r and omised controlled trials .
Effects of iron deficiency on attention and learning processes in preschool children: Bandung, Indonesia.
A double-blind clinical trial was conducted in Indonesia to assess effects of iron supplementation on performance of iron-depleted and iron-deficient anemic children in discrimination and oddity learning tasks . Half these children received elemental Fe for 8 wk ; the others received a placebo . There were significant changes from pre- to postintervention evaluations in ferritin , transferrin saturation , free erythrocyte protoporphyrin , and hemoglobin among the anemic and iron-depleted children ; no changes were observed among the placebos or any of the iron-replete children . The magnitude of hematological changes in anemic children treated with iron was small ; yet , after treatment the children 's mean ferritin , transferrin saturation , and hemoglobin values were above the cutoff points used for the definition of iron-deficiency anemia ( IDA ) . Pre- and posttreatment psychological test data show that IDA produces alterations in cognitive processes related to visual attention and concept acquisition , alterations reversed with iron treatment
