Fiber fix for brain fog? new study tests Gut-Brain link in injury recovery
NCT ID NCT06607523
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a common dietary fiber called inulin can improve fatigue and thinking problems in people recovering from brain injuries. Researchers will give inulin to 130 adults in neurorehabilitation and track changes in their gut bacteria and symptoms. The goal is to see if altering the gut microbiome can ease brain-related symptoms during recovery.
