There is ample evidence that iron is an essential trace element, but assessment of iron status and decisions on the amounts needed and the means of delivery in patients on parenteral nutrition (PN) have been unclear. Although iron requirements may diminish during acute illness, the frequent concurrence of blood loss and iron deficiency argue strongly for maintenance of levels of delivery in line with basal requirements. Maintenance of iron delivery has not been thought likely to present risk, but new data are questioning this. The needs of menstruating, pregnant, and lactating women are greater than those of adult men. The evidence favors an intravenous dose of around 1 mg of elemental iron per day in adult men and postmenopausal women. Doses of 1.5 g/d in menstruating women and 2.0 g/d for those in the later stages of pregnancy or lactating can be supported. A calibrated response is required in the growing child. Continued monitoring of iron status is recommended. Iron is an essential component for most PN regimens. The quantity of iron to be included should take account of predicted requirements.
