Gummy supplements aim to heal gut bacteria after cancer surgery
NCT ID NCT07050485
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a daily postbiotic gummy can help restore healthy gut bacteria after surgery for colon or other gastrointestinal cancers. Thirty adults scheduled for surgery will be randomly assigned to receive either the postbiotic or a placebo gummy for two weeks after their operation. The main goal is to see if the supplement improves the diversity of bacteria in their stool compared to the placebo group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- postbiotic supplement (PoZibio gummy)
- What this could lead to
- If it works, this could point toward a simple way to help restore healthy gut bacteria after gastrointestinal cancer surgery.
- What could go wrong
- This is a very small early-stage trial with only 30 people. It only measures changes in gut bacteria, not whether patients feel better or have fewer complications.
