Studies suggest that bioactive compounds such as probiotics may positively influence psychological health. This study aimed to determine whether supplementation with the probiotic Lactobacillus rhamnosus HN001 reduced stress and improve psychological wellbeing in university students sitting examinations. The study was a randomized, double-blind, placebo-controlled design, in which 483 undergraduate students received either the probiotic L. rhamnosus HN001, or placebo, daily during a university semester. Students completed measures of stress, anxiety, and psychological wellbeing at baseline and post-intervention before examinations. T-tests compared the change in psychological outcomes between groups.
