This research study will determine iron needs in a representative sample of adults living in the US using the iron isotope dilution technique. Following administration and equilibration of a stable iron isotope, participants will be followed for a 12 week study period. Blood will be collected every 4 weeks and the isotopic composition will be determined. Results will help update dietary iron guidelines making sure they better match the specific needs of the US population.",[79],"Iron Absorption",[81,82,83,84,85,86],"Iron absorption","Iron losses","Iron requirements","Iron deficiency","Iron deficiency anemia","Iron isotopes","2026-04-23",{"date":89,"type":90},"2026-04-29","ACTUAL",{"date":92,"type":90},"2026-02-06",{"date":94,"type":73},"2029-05-31",{"name":5,"class":6},2]
