Gut health is closely linked to mental well-being through the “gut-brain axis”, a communication network between the gut and the brain. The gut microbiome (the collection of microorganisms in the digestive tract) plays a significant role in producing neurotransmitters like serotonin, which influences mood. A healthy, diverse gut microbiome supports mental health, while an imbalance (dysbiosis) can contribute to mood disorders like anxiety and depression.
