Could Your Gut Be the Missing Link to
Better Sleep, Focus and Mood?

Your brain relies on chemical messengers called neurotransmitters to regulate mood, focus, and overall mental well-being. Three of the most important are serotonin, dopamine, and GABA  and each plays a unique role in how you feel and function.

​

• Serotonin is often called the “feel-good” neurotransmitter. It helps stabilise mood, promotes restful sleep, and supports emotional balance. Low serotonin levels are linked to feelings of sadness, anxiety, irritability, and poor sleep.

​​

• Dopamine is the “motivation and reward” chemical. It drives focus, learning, and the sense of satisfaction when you achieve something. When dopamine is low, you may feel unmotivated, distracted, or struggle with concentration, symptoms often seen in ADHD and low mood.

 

• GABA (gamma-aminobutyric acid) acts as the brain’s “calming” neurotransmitter. It helps reduce stress and prevents overstimulation of the nervous system. A lack of GABA can lead to racing thoughts, tension, anxiety, or trouble relaxing and sleeping.

​

Research now shows that many of these neurotransmitters are influenced by the balance of bacteria in your gut often referred to as the gut–brain connection. Through targeted nutrition, lifestyle support, and evidence-based gut restoration strategies, we can help rebalance your microbiome and, in turn, support healthier neurotransmitter function and emotional well-being.
