Could a potato starch supplement help veterans with liver disease and PTSD?
NCT ID NCT06464952
First seen Apr 21, 2026 · Last updated Jun 24, 2026 · Updated 8 times
Summary
This study looks at whether a prebiotic called resistant potato starch can change the gut microbiome in veterans who have both cirrhosis (liver scarring) and PTSD. Researchers will compare the starch to a placebo (cellulose) in 30 participants. The main goal is to see if the starch increases beneficial gut bacteria, which might eventually help with brain and liver health.

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 (a prebiotic fiber)
What this could lead to
If it works, 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 early, small study with only 30 participants. It is designed to measure changes in gut bacteria, not to treat symptoms, so any health benefits are uncertain.
