NCT05990166

  • Ages 18-35
  • Female

Study Summary

The goal of this clinical trial is to determine if taking a mineral-enriched powder can raise blood iron levels compared to a placebo powder in reproductive-aged women with iron deficiency. The main questions it aims to answer are:

  • Does the mineral-enriched powder raise blood iron levels compared to a placebo powder in women when it is taken every day for six months?

  • How many participants still have iron deficiency after six months of taking the mineral-enriched powder compared to a placebo powder?

Participants in this clinical trial will drink the mineral-enriched powder containing ferrous iron and zinc sulphate monohydrate or a placebo powder mixed with 1 litre of water daily for six months. The placebo is a look-alike substance that does not contain active ingredients (iron and zinc). Participants will also have to:

  • Complete an online "study diary" every two weeks for six months

  • Provide a blood sample once a month for six months

  • Attend three in-person visits with a researcher, at enrolment (baseline), midline (three months), and endline (six months)

  • Complete three sets of online questionnaires (following each in-person visit)

  • Complete three sets of dietary assessments (following each in-person visit)

  • Provide three stool samples (following each in-person visit)
