Snack your way through menopause? new trial tests a granola bark for hot flushes and mood swings
NCT ID NCT07599930
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a daily snack rich in plant chemicals and fibre can ease perimenopause symptoms like hot flushes, mood changes, and sleep problems. Twenty women aged 40-55 who are not on hormone therapy will eat either the special snack or a placebo for several weeks, then switch. Researchers will also check if changes in gut bacteria help explain any benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cinnamon Granola Bark (phytochemical and fibre-rich snack)
- What this could lead to
- If it works, this snack could offer a natural way to reduce common perimenopause symptoms like hot flushes, mood swings, and poor sleep.
- What could go wrong
- This is a very small early trial with only 20 participants, so results may not apply widely. The snack is not a treatment and may not work better than a placebo.
