Gut-Brain fix for hot flushes? small study tests polyphenols & probiotics
NCT ID NCT06333223
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a combination of polyphenols (plant compounds) and probiotics (good bacteria) can improve menopause symptoms like hot flushes, low mood, and sleep trouble. Sixteen postmenopausal women took the supplement to see if it changed blood chemistry, body mass index, and gut bacteria. The goal was to find a natural way to ease symptoms by targeting the gut-brain connection.
