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 three different iron supplementations in term healthy infants after 5 months of life.
The aim of this study was to investigate the effects of different doses of iron on haematological status of breastfed infants . One hundred and thirteen infants were r and omized into four groups at 5 months of age .  Iron supplementation was given at doses of 1 mg/kg/day , 2 mg/kg/day , and 2 mg/kg/every other day in the first three study groups , respectively , and the last group received placebo . The hematological values , except hemoglobin , were higher in the group supplemented with iron at a dose of 2 mg/kg/day , and ferritin values were statistically higher in the group supplemented with iron at a dose of 2 mg/kg/every other day than in the group supplemented with iron at a dose of 1 mg/kg/day . We suggest that intermittent iron supplementation is more effective than a daily regimen in equal dosages
