You’ve probably heard the saying “trust your gut” — but did you know there’s real science behind it?
Your gut and brain are in constant communication through a network called the gut-brain axis. In fact, your gut is often referred to as your "second brain" — and it plays a much bigger role in your mood, focus, energy, and overall mental health than you might realize.
Here's how it works:
Your Gut Is a Major Producer of Neurotransmitters
Over 90% of your body’s serotonin — the neurotransmitter that influences happiness, sleep, and mood stability — is produced in the gut. Other important chemicals like dopamine and GABA (which help regulate pleasure, motivation, and relaxation) are also closely tied to gut function.
When your gut is inflamed, imbalanced, or struggling with issues like dysbiosis (an unhealthy microbial balance), it can throw off your neurotransmitter production — leading to symptoms like anxiety, depression, irritability, brain fog, or low energy.
The Microbiome Directly Talks to Your Brain
Your gut is home to trillions of bacteria, and the health of these microbes impacts how you feel mentally and emotionally. A thriving, diverse microbiome helps produce calming neurotransmitters, regulates stress hormones, and protects against inflammation that can negatively affect the brain.
On the flip side, an imbalanced gut microbiome can trigger chronic low-grade inflammation, which has been linked to depression, cognitive decline, and increased stress response.
Stress Impacts Your Gut — and Vice Versa
It’s not just a one-way street. Stress, anxiety, and emotional upset can change gut motility, disrupt your microbiome, and increase gut permeability ("leaky gut"), setting the stage for digestive problems (heartburn, bloating, diarrhea, constipation, SIBO) and further fueling mental health challenges.
This creates a vicious cycle: poor gut health affects the brain, and poor mental health affects the gut.
The Good News? You Have the Power to Break the Cycle
Supporting your gut through real food, hydration, proper digestion, stress management, daily movement and targeted supplementation can dramatically shift how you feel — both physically and mentally.
If you’ve been battling chronic symptoms like bloating, constipation, brain fog, anxiety, poor sleep, or fatigue, it’s worth exploring what’s going on in your gut. Healing the gut isn’t just about digestion — it’s about total-body (and mind) transformation.
4 things you can begin doing TODAY to reboot your Gut-Brain Axis:
1. Pause Before You Eat: Activate “Rest to Digest” Mode
Take 3–5 deep belly breaths before meals. This simple habit shifts your body from fight-or-flight into parasympathetic mode—aka “rest and digest”—so your gut can break down food properly, absorb nutrients, and reduce bloating or discomfort.
2. Start Your Day with a Protein-Rich Breakfast
Ditch the sugary cereals and go for eggs, a protein smoothie, or leftover chicken and veggies. Protein stabilizes blood sugar, supports neurotransmitter production (like dopamine and serotonin), and helps regulate mood and focus all day long.
3. Incorporate a Daily 5-Minute Meditation
Even just five minutes of mindful breathing or guided meditation can reduce stress hormones that wreak havoc on your gut lining and microbiome. A calmer mind = a calmer gut. Try it before bed or after meals to reset your nervous system.

4. Ditch Ultra-Processed Foods & Artificial Sweeteners
These gut disruptors can inflame the lining of your digestive tract and throw off microbial balance—both of which directly impact brain function and emotional wellbeing. Focus on real, whole foods with ingredients you can pronounce.
