Could a potato starch supplement help veterans with liver disease and PTSD?

NCT ID NCT06464952

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing whether a prebiotic called resistant potato starch can change the gut microbiome in 30 veterans who have both cirrhosis (liver scarring) and PTSD. Participants will take either the potato starch or a placebo (cellulose) for a period, and researchers will measure changes in gut bacteria diversity and bile acids. The goal is to understand if this simple supplement can improve gut health, which might eventually help with brain function and PTSD symptoms.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
resistant potato starch
What this could lead to
If successful, this could point toward a simple dietary supplement to improve gut health and possibly brain function in people with cirrhosis and PTSD.
What could go wrong
This is a very small, early-stage study with only 30 participants, so results may not apply widely. It is designed to observe changes, not to prove a treatment works.
