Gut health hack: probiotics may supercharge psoriasis drug
NCT ID NCT07169019
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This early-stage study tests whether adding daily probiotics to weekly methotrexate can improve psoriasis symptoms and gut bacteria in newly diagnosed adults. 24 participants will either get probiotics plus methotrexate or methotrexate alone for 4 months. Researchers will compare changes in skin severity and stool samples to see if the combination works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- probiotics and methotrexate
- What this could lead to
- If it works, this could point toward a simple, low-cost way to boost the effectiveness of standard psoriasis treatment by improving gut health.
- What could go wrong
- This is a very early, small pilot study with only 24 people. The results may not apply to everyone, and the combination might not work better than methotrexate alone.
