Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e 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.
