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 .
The effect of iron in formula milk after 6 months of age.
Ninety two normal birthweight infants aged 6 months entered a double blind controlled trial which compared a follow on formula milk with no added iron against the same formula milk containing 1.2 mg of iron per 100 ml . There was no significant difference in the social class or demographic characteristics of the two treatment groups or in the proportion of each group completing the trial . There was no difference between the two groups in the quantity of milk taken but the amounts taken lessened between 6 and 18 months of age . There was no difference between the two groups with respect to mean haemoglobin and median serum ferritin at 6 , 9 , 12 , 15 , and 18 months of age . Very few infants developed iron deficiency anaemia in either group but there was a tendency for serum ferritin levels to fall between 6 and 18 months of age in both groups . The results suggest that iron added to follow on milk was not an important source of dietary iron in the infants studied
