Study Summary
The purpose of this study is to investigate the effect of daily iron supplements after blood donation on time to recovery of hemoglobin and iron stores. The study will also determine whether the effect of iron supplements on time to recovery is different in men and women, in older vs. younger donors (\<60 years old vs. at least 60 years old) and in donors with replete vs. diminished pre-donation iron stores.
Primary Outcome
Hemoglobin will be measured 3-7 days and 2, 4, 8, 12, 16 and 24 weeks after blood donation. A nonlinear regression of hemoglobin vs time since donation will be used to determine time to recovery of hemoglobin to 80% of the pre-donation level.
