Could tempeh and vitamin d ease IBD symptoms?
NCT ID NCT07656233
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether taking tempeh powder (a source of isoflavones) and vitamin D3 daily for 8 weeks could improve vitamin D levels, reduce inflammation, and boost quality of life in people with inflammatory bowel disease (IBD). Fifty adults with ulcerative colitis or Crohn's disease took part. The goal was to see if these supplements, added to standard care, offer extra benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tempeh isoflavone and vitamin D3 supplements
- What this could lead to
- If it works, this could point toward a simple dietary supplement to help manage inflammation and improve quality of life in people with inflammatory bowel disease.
- What could go wrong
- This is a small, early-stage trial with only 50 participants and no blinding, so results may not be reliable or apply to everyone. Supplements may not significantly change disease outcomes.
