Gut health boost? probiotic blend tested for menopause symptom relief
NCT ID NCT06604234
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a daily probiotic capsule containing three bacterial strains could improve quality of life and reduce menopause symptoms in 245 women aged 45-60 who were in perimenopause or early postmenopause. Participants took either the probiotic or a placebo for several weeks, and their symptoms and well-being were tracked using standard questionnaires. The goal was to see if this simple supplement could offer relief without hormones.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a blend of three probiotic strains (Levilactobacillus brevis, Lactiplantibacillus plantarum, and Pediococcus acidilactici)
- What this could lead to
- If it works, this could offer a natural, non-hormonal option to help manage menopause symptoms and improve daily well-being.
- What could go wrong
- This is a completed study, but probiotics are not a proven treatment for menopause. The effect may be small or no better than a placebo, and results may not apply to all women.
