NCT ID NCT07331987
First seen Jun 26, 2026 · Last updated Jun 30, 2026 · Updated 3 times
Summary
This study tests whether taking probiotics daily for 3 months can reduce symptoms of anxiety and depression in 60 adults with mild-to-moderate conditions. Participants will receive either probiotics, a placebo, or the antidepressant escitalopram. Researchers will measure changes in mood, sleep, and gut bacteria to see if probiotics offer a safe, natural way to support mental health.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Probiotics (beneficial bacteria) and escitalopram (an antidepressant)
What this could lead to
If it works, this could point toward a simple, natural supplement to help manage mild-to-moderate anxiety and depression alongside standard care.
What could go wrong
This is a small, early-stage trial with only 60 people. Probiotics may not outperform placebo, and results may not apply to everyone with anxiety depression.
