Which iron pill works best? new study aims to find out
NCT ID NCT07556731
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of iron supplements—standard ferrous salt and a newer liposomal form—in adult women with iron-deficiency anemia caused by heavy menstrual bleeding. About 100 women will take one of three treatments daily or every other day for three months. Researchers will measure how well each treatment raises hemoglobin levels and track any stomach-related side effects.
