Probiotics' secret journey: from mouth to vagina?

NCT ID NCT07246161

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether friendly bacteria taken by mouth can travel to the vagina. Seventy-two healthy women will take a daily probiotic capsule for 4 weeks. Researchers will check vaginal swabs for the probiotic strains at several time points. The goal is simply to see if the bacteria make the trip, not to treat any condition.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Probiotic formula (Lactobacillus and Bifidobacterium strains)

What this could lead to

If successful, this could show that oral probiotics can travel to the vagina, potentially supporting future probiotic-based approaches for vaginal health.

What could go wrong

This is a small, early-stage study in healthy women only. It measures whether the probiotics appear in vaginal samples, not whether they improve health or prevent infection.
