The gut-brain axis: how your stomach influences your mind

The gut and brain are in constant communication through the vagus nerve, hormonal signals, and metabolites produced by gut bacteria. This bidirectional link is called the gut-brain axis.

Certain strains of bacteria, sometimes called 'psychobiotics', have been shown in clinical studies to influence the production of neurotransmitters like serotonin and GABA — chemicals directly involved in mood and relaxation.

This is part of why gut imbalance is so often linked to poor sleep and elevated stress: an unhealthy microbiome can disrupt the signals that help regulate your nervous system.

Supporting your gut with the right strains, alongside good sleep hygiene, is a simple but often overlooked lever for emotional resilience.
