Probiotics for sharper thinking? new study tests the hype

This study looked at whether taking a daily probiotic supplement for 8 weeks can improve thinking, memory, and digestion in generally healthy adults. 85 participants were randomly assigned to receive either probiotics or a placebo. Researchers measured cognitive lapses, gut symptoms, mood, and drinking/eating behaviors using online questionnaires. The goal was to see if probiotics offer any real benefits for everyday wellbeing.
