Brief Summary

The prevalence of iron deficiency in blood donors has been demonstrated to be a direct consequence of repeat blood donations. Given the adverse effects of iron deficiency, it is priority to implement programs to remediate iron deficiency issues associated with blood donations. To explore this issue, the study's aims to:

  • Receive a thank you letter after each blood donation.
  • Receive a letter informing them of their ferritin result at each visit, along with recommendations for blood donation.
  • Receive pills to take daily that contain no iron (a placebo or inert pill).
  • Receive pills to take daily that contain 19 mg of iron (the typical amount in a multivitamin with iron).
  • Receive pills to take daily that contain 38 mg iron (the typical amount in an over-the-counter iron supplement).
