Sensitivity analyses and meta-regression for hemoglobin suggested a higher response with lower trial quality ( suboptimal allocation concealment and blinding ) , use of condiments , and sodium iron edetate and a lower response when adults were included .
Consumption of iron-fortified foods results in an improvement in hemoglobin , serum ferritin , and iron nutriture and a reduced risk of remaining anemic and iron deficient
BACKGROUND The utility of iron fortification of food to improve iron deficiency , anemia , and biological outcomes is not proven unequivocally .
Lack of adverse reactions to iron-fortified formula.
Some physicians are reluctant to recommend feeding of iron-fortified formulas to infants because of a fear of adverse reactions . In crossover studies , parents ' records were compared with regard to their  infant 's  behavior ( fussiness , cramps , regurgitation , flatus , colic ) and stool characteristics during periods when iron-fortified formulas were fed and periods when non-iron-fortified formulas were fed . No statistically significant feeding-related difference was noted except for stool color
