The gut/brain axis

Why is the gut microbiome so important for mental and emotional health?

The gut is often called the "second brain" because it plays a major role in producing neurotransmitters like serotonin, dopamine, and GABA — all essential for emotional regulation, sleep, focus, and mental stability. When the gut microbiome is imbalanced (due to antibiotics, poor diet, stress, toxins, etc.), it can lead to systemic inflammation and produce neurotoxins that affect how the brain functions. This can contribute to symptoms like anxiety, low mood, brain fog, hyperactivity, or emotional instability.

.Why is the gut microbiome often connected with stress?

An imbalanced microbiome can also be linked to an overstimulated or underactive VAGUS NERVE which is the most active in the gut but also sends signals to the brain. The vagus nerve is a vital part of the parasympathetic nervous system — often referred to as the "rest and digest" system. It plays a central role in regulating stress response, digestion, inflammation, heart rate, mood, and overall calmness in the body. When the vagus nerve is underactive or overstimulated, it can lead to symptoms like anxiety, gut issues, fatigue, and emotional imbalance.
