NCT ID NCT07544797
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding pea fiber to the daily diet of people on dialysis can lower harmful waste products in their blood. 72 adults on dialysis will eat baked goods with or without pea fiber for 8 weeks. Researchers will measure changes in toxin levels and heart health markers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pea fiber (prebiotic)
- What this could lead to
- If it works, this could offer a simple, food-based way to reduce harmful toxins and possibly lower heart disease risk in people on dialysis.
- What could go wrong
- This is a small, early-stage trial with only 72 participants. Previous studies on fiber have shown mixed results, so there is no guarantee it will work.
