Gut bacteria may soothe menopause symptoms — a trial puts it to the test
NCT ID NCT07759908
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial tests whether a daily synbiotic supplement, combining probiotics and a prebiotic fiber, can ease common perimenopause and menopause symptoms like poor sleep, anxiety, and brain fog. Women aged 44–55 experiencing these symptoms will take either the active supplement or a placebo for 8 weeks. The study also looks at effects on gut and vaginal health, offering a potential natural, non-hormonal approach to support women during this transition.
