1. Gut-Brain Axis 

Psychobiotics are live microorganisms, predominantly bacteria, that confer mental health benefits when ingested in adequate amounts. They act as microbial superheroes, promoting a positive balance in the gut microbiome. 

2. What Are Psychobiotics?

Certain strains of probiotics, when introduced into the gut, produce neurotransmitters like serotonin and gamma-aminobutyric acid (GABA), contributing to improved mood and reduced stress levels.
