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 .
Iron-fortified formulas and gastrointestinal symptoms in infants: a controlled study, With the cooperation of The Syracuse Consortium for Pediatric Clinical Studies.
In an attempt to determine whether iron-fortified infant formulas produced gastrointestinal symptoms in infants , we fed two similar formulas , one with and one without iron fortification , to a group of 93 term infants upon discharge from the nursery on the third day of life . Infants were fed the formulas for a period of 42 days while their mothers kept detailed daily records of all gastrointestinal symptoms . A total of 49 infants were fed the non-iron-fortified formula and 44 infants were fed the iron-fortified formula .  Review of the records revealed no differences in the number of stools per day , the description of the stools , the number of days without stools , the incidence or frequency of colic , spitting-up , or vomiting . We conclude that the feeding of iron-fortified formulas to infants does not produce an increased incidence of gastrointestinal symptoms or signs
