Summary

This study tests whether taking a daily probiotic supplement for 8 weeks can reduce stress and anxiety in healthy university students during exam time. Two hundred students will receive either the probiotic or a placebo. Researchers will measure changes in stress, anxiety, sleep quality, and gut symptoms using questionnaires.

What this could mean

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

Active substance
Probiotics (Lactobacillus plantarum LP140 and Bifidobacterium breve BB010)
What this could lead to
If it works, this could point toward a simple, safe way to help manage stress and anxiety in healthy people during high-pressure periods.
What could go wrong
This is a small, early-stage study in healthy students, so results may not apply to everyone. The effect may be small or no different from placebo.
