Probiotics Found to Reduce Negative Mood in Healthy Adults, Study Shows

Clinical trial highlights the gut-brain connection and reveals potential mental health benefits of daily probiotic supplementation.

A randomized, double-blind, placebo-controlled trial with 88 participants found that probiotics significantly reduced negative mood after two weeks of daily supplementation.
The study used innovative daily mood tracking methods, which captured subtle emotional changes missed by standard psychological questionnaires.
While negative mood improved, positive mood levels remained unaffected, indicating a targeted impact on reducing negative emotions.
Participants with higher baseline risk aversion experienced the most significant mood improvements, suggesting individual variability in response to probiotics.
Experts caution that probiotics should not replace traditional psychiatric treatments but may serve as a complementary approach to mental health care.
