A recent study by researchers at Leiden University suggests that daily probiotic intake can alleviate negative emotions such as anxiety, stress, and fatigue. The study, conducted by Dr. Katerina Johnson and Dr. Laura Steenbergen, involved young, healthy adults who consumed probiotics containing Lactobacillus and Bifidobacterium strains for a month. Participants reported improved moods after approximately two weeks, as measured by daily mood assessments.
Unlike traditional antidepressants, which often dampen both negative and positive emotions, the probiotics appeared to specifically reduce negative feelings without affecting positive ones. Additionally, individuals with traits like risk avoidance experienced more pronounced mood improvements. The study also noted slight enhancements in participants’ ability to recognize facial expressions, indicating potential benefits in emotional processing.
While these findings are promising, the researchers caution that probiotics should not replace antidepressants. However, they may serve as a supplementary approach to mental well-being. The study emphasizes the importance of simple daily mood tracking in psychological research, as it proved more sensitive to changes than standard questionnaires.
