NCT ID NCT04250298
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study looked at whether taking an iron supplement called sucrosomial iron for three months can raise hemoglobin levels in blood donors who have iron deficiency. Fifty donors with low iron took the supplement daily. Researchers measured changes in hemoglobin, ferritin, fatigue, sleep, and quality of life. The goal was to see if this supplement could help donors recover their iron stores and feel better.
