First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial explores whether adding vitamin D and iron supplements to usual OCD treatment can improve the ability to control impulses. It involves 60 people with OCD who will receive the supplements for 12 weeks. Researchers will use brain scans and behavioral tasks to see if these supplements affect brain chemicals linked to self-control and immune function.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- calcitriol (a form of vitamin D) and iron supplements
- What this could lead to
- If successful, this could point toward a simple supplement-based add-on to help people with OCD better control impulses and reduce symptoms.
- What could go wrong
- This is a small, early-stage trial with no control group, so results may not be conclusive. Supplements may not affect brain chemistry as hoped, and individual responses can vary.
