Measuring Erythrocyte Iron Incorporation From Different Dosing Regimens in Anemic Women

Completed

• Conditions: Iron Deficiency Anemia

• Registration Number: NCT03623997
• Lead Sponsor: Swiss Federal Institute of Technology

Brief Summary

Iron-deficient anaemic subjects are likely to benefit most from oral iron supplements, but supplementation schedules vary widely in clinical practice, absorption is low and compliance is poor due to mild gastrointestinal side effects. The investigators will compare iron absorption from labeled oral iron doses of 100mg and 200mg administered either on two consecutive days or on alternate days in young anemic women.
