Physiologic requirement for iron in pregnant women, assessed using the stable isotope tracer technique.

ABSTRACT:

Background

Knowledge of the physiologic requirement for iron, the core index for the formulation of a dietary reference intake (DRI), is of great importance for the health of a pregnant woman and her fetus, and can help a mother accurately plan her iron supplementation. However, direct measurements of the physiologic requirement for iron during pregnancy are still lacking.

Method

Eleven women of reproductive age from Hebei Province, China, who planned to become pregnant in the near future, were enrolled between January and March 2015 and included in the final analysis. Subjects participated in a 2-week metabolic trial in which they consumed 50 mg of the stable isotope ⁵⁸Fe, and were then followed for ~ 2 years. The abundance of ⁵⁸Fe and the total iron c
