Summary

This study looks at how much iron healthy US adults actually need. Current guidelines are based mostly on European data, so researchers want to update them for Americans. About 300 men and premenopausal women aged 18–50 will take a safe, stable iron isotope and give blood samples over 12 weeks. The results will help make sure dietary iron recommendations match the needs of the US population.
