Summary

This study tests whether a dietary fiber supplement called resistant potato starch can improve gut health and quality of life in veterans with Gulf War Illness (GWI). About 52 veterans aged 50-85 with GWI and gut symptoms will take the supplement daily. Researchers will measure changes in gut bacteria and related metabolites, as well as symptom improvements.
