Iron fix: new study tests best way to boost energy in women with hidden deficiency
NCT ID NCT06437080
First seen Jun 24, 2026 · Last updated Jul 22, 2026 · Updated 3 times
Summary
This study looked at 1331 women aged 18-45 who had low iron stores but normal hemoglobin (no anemia). They were split into three groups: one got daily oral iron pills for 3 months, another got three IV iron infusions over 3 months, and a third got no treatment. The goal was to see which approach raised iron levels and eased symptoms like fatigue and poor concentration after 4 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Iron (oral iron III hydroxide polymaltose complex or IV ferric carboxymaltose)
- What this could lead to
- If successful, this could show that iron supplements improve symptoms like fatigue and brain fog in women with low iron but normal blood counts.
- What could go wrong
- This is a completed trial, but results may not apply to all women. Oral iron can cause stomach upset, and IV iron carries rare allergy risks.
