Iron-Deficient but not anemic? new study tests simple fix
NCT ID NCT07263529
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at 60 women aged 18-55 who have low iron stores but normal blood counts. First, they get two months of dietary advice to eat more iron-rich foods. Then, those who still have low iron take an iron pill daily for one month. The goal is to see if this approach can prevent anemia and improve symptoms like tiredness and dizziness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oral ferrous sulfate (80 mg elemental iron daily for one month) and dietary counseling
- What this could lead to
- If successful, this could show that early iron treatment in women with low iron stores prevents progression to anemia and improves symptoms like fatigue.
- What could go wrong
- This is a small, early-phase study with only 60 participants and no control group, so results may not apply widely. The dietary and iron interventions are short-term, and long-term benefits are unknown.
