Psychobiotics are a class of probiotics that have a positive effect on mental health. They are live bacteria that, when consumed, can influence the gut-brain axis, a communication network linking the gut and the brain. Research suggests that these beneficial microbes may help alleviate symptoms of anxiety, depression, and stress by producing neurotransmitters and other compounds that affect mood. The concept of psychobiotics is rooted in the idea that gut health is closely connected to mental well-being. By improving gut microbiota through dietary changes or supplements, individuals may experience enhanced emotional resilience and cognitive function. This emerging field highlights the importance of gut health in overall mental health.
