Vitamin D3 as a Gut-Soothing sidekick for IBD patients?
NCT ID NCT04225819
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding high-dose vitamin D3 to standard anti-TNF therapy can improve symptoms and reduce inflammation in people with active Crohn's disease or ulcerative colitis. About 100 adults starting anti-TNF treatment will receive either vitamin D3 or a placebo for 14 weeks. The goal is to see if vitamin D3 helps control the disease better than anti-TNF therapy alone.
