Gut check: probiotics and prebiotics tested for spinal cord injury relief
NCT ID NCT06870331
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking probiotics or prebiotics daily for eight weeks can ease stomach and bowel problems in people with chronic spinal cord injury. Fifty participants will try both supplements in a crossover design, with a four-week break in between. The researchers will measure changes in gut symptoms, gut bacteria, inflammation, and how fast food moves through the digestive system.
