Vitamin D Boost May Help Reset Immune Response in Some IBD Patients
A study in Cell Reports Medicine followed 48 adults with inflammatory bowel disease and low vitamin D, giving 50,000 IU of vitamin D weekly for 12 weeks. After three months, many participants reported better quality of life, reduced disease activity, and lower inflammatory markers in stool, with the immune system shifting toward greater tolerance of gut bacteria and a more favorable gut microbiome. The findings suggest vitamin D can support immune and gut health in IBD and possibly other autoimmune conditions, though it’s not a universal cure and dosing should be guided by a clinician through regular blood work and tailored advice.
