Could a daily postbiotic pill tame exercise inflammation and soothe your gut?
NCT ID NCT07387991
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a multi-strain postbiotic supplement taken daily for 28 days can reduce inflammation, improve gut symptoms, and aid recovery after exercise in healthy adults. About 50 physically active men and women aged 18 to 55 will be randomly assigned to receive either the supplement or a placebo. After four weeks, they will run on a treadmill, and researchers will measure blood markers of inflammation and immune function, as well as gut symptoms, anxiety, and perceived recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Multi-Strain Postbiotic (dietary supplement)
- What this could lead to
- If it works, this could point toward a simple supplement to help reduce exercise-related inflammation and gut discomfort.
- What could go wrong
- This is a small, early-stage trial in healthy adults, so results may not apply to people with medical conditions. The supplement may show no benefit over placebo.
