AB Iron  is  the  most  abundant  metal  on  earth,  and  despite  that,  iron  deficiency  is  the  most  prevalent  single  nutrient  deficiency  worldwide.  Term  newborns  possess  about  75  mg  of  elemental  iron/kg  (0.25–0.5  g  of  total  body  iron),  largely  acquired  during  transfer  of  maternal  iron  stores  during  the  third  trimester  of  pregnancy.  They  must  then  gain  4.5  g  of  iron  over  the  course  of  their  childhood  (1  mg/day)  to  achieve  the  nearly  5.0  g  of  body  iron  in  the  average  adult.  An  additional  0.2  to  0.5  mg/day  of  absorbed  iron  is  required  to  balance  normal  physiologic  iron  losses.
