Vitamin d may unlock iron absorption in IBD patients
NCT ID NCT07673497
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study investigates whether giving vitamin D supplements to adults with inflammatory bowel disease (Crohn's disease or ulcerative colitis) who also have low vitamin D levels can improve their iron status. Participants take high-dose vitamin D3 weekly for 8 weeks, then a lower daily dose, and are checked after 3 months. The goal is to see if correcting vitamin D deficiency helps the body use iron better, potentially reducing the need for iron infusions.
