About the trial

What the trial wants to find out

This will be a randomized clinical trial. Enrolled subjects will be randomized (1:1) into two study arms to receive either daily (Group 1) or alternate day (Group 2) supplementation with one oral pill containing ferrous sulfate with an equivalent elemental iron dose of 65 mg per pill.

The 2 groups in the trial

  • 1) Daily dose of ferrous sulfate with an equivalent elemental iron dose of 65 mg per pillTreatment being tested

    daily (Group 1) supplementation with one oral pill containing ferrous sulfate with an equivalent elemental iron dose of 65 mg per pill

    Treatment: daily ferrous sulfate with an equivalent elemental iron dose of 65 mg per pill

  • 2) Alternate daily dose of ferrous sulfate with an equivalent elemental iron dose of 65 mg per pillTreatment being tested

    alternate day (Group 2) supplementation with one oral pill containing ferrous sulfate with an equivalent elemental iron dose of 65 mg per pill

    Treatment: alternate day ferrous sulfate with an equivalent elemental iron dose of 65 mg per pill

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
