Consequently, iron deficiency is common in CeD, impacting at least 10% of newly diagnosed individuals. In this narrative review, we aim to investigate the mechanisms, prevalence, treatment, and monitoring of iron deficiency and the impacts of a gluten-free diet (GFD) on iron deficiency in individuals with CeD. We will also review the role of and approach to iron supplementation in this population. Specifically, we will explore whether mucosal healing on a GFD is sufficient for the management of iron deficiency amongst individuals with CeD.<\/jats:p>","DOI":"10.3390\/nu18040590","type":"journal-article","created":{"date-parts":[[2026,2,11]],"date-time":"2026-02-11T11:13:15Z","timestamp":1770808395000},"page":"590","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Ironing Out the Deficiency: Tracking Iron in Celiac Disease Before and After the Gluten-Free Diet"],"prefix":"10.3390","volume":"18","author":[{"given":"Patricia","family":"Dillawn","sequence":"first","affiliation":[{"name":"Department of Pediatrics, University of Colorado School of Medicine, Aurora, CO 80045, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8145-8229","authenticated-orcid":false,"given":"Sadie","family":"Nagle","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, University of Colorado School of Medicine, Aurora, CO 80045, USA"},{"name":"Colorado Center for Celiac Disease, Digestive Health Institute, Children\u2019s Hospital Colorado, Aurora, CO 80045, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edwin","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Colorado School of Medicine, Aurora, CO 80045, USA"},{"name":"Colorado Center for Celiac Disease, Digestive Health Institute, Children\u2019s Hospital Colorado, Aurora, CO 80045, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9656-5561","authenticated-orcid":false,"given":"Marisa Gallant","family":"Stahl","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Colorado School of Medicine, Aurora, CO 80045, USA"},{"name":"Colorado Center for Celiac Disease, Digestive Health Institute, Children\u2019s Hospital Colorado, Aurora, CO 80045, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"625","DOI":"10.1080\/17474124.2022.2089114","article-title":"Pathophysiology and therapeutic management of anemia in gastrointestinal disorders","volume":"16","author":"Bergamaschi","year":"2022","journal-title":"Expert Rev.
