🧠 5 Mind-Blowing Facts About Your Brain
(That All Start in Your Gut)

Dear Friends,

Have you ever wondered why you feel foggy, anxious, or down—even when your labs look “normal”?
The answer may lie not in your brain, but in your gut.

Here are 5 mind-blowing facts about your brain that all stem back to your gut. Watch my short video above for a quick summary!
 

1. 90% of your serotonin is made in your gut—not your brain.
That “feel-good” neurotransmitter responsible for mood, sleep, and focus? It’s mostly produced by your gut microbes! The same goes for melatonin, the sleep hormone. 
 

2. Dysbiosis (an imbalance of gut bacteria) can trigger brain symptoms.
When harmful bacteria outnumber beneficial ones, it can lead to brain fog, anxiety, and even depression. This is why probiotics have been scientifically proven to improve mood and mental health outcomes.
 

3. Leaky gut allows bacterial toxins (like LPS) to cross the blood-brain barrier. Increased translocation of gram-negative bacteria plays a role in the inflammatory pathophysiology of depression. These toxins trigger neuroinflammation, a root cause of fatigue, poor memory, and cognitive decline.
 

4. Your gut microbes influence how your brain ages.
An unhealthy gut has been linked to increased risk of Alzheimer’s disease and other neurodegenerative conditions.
 

5. The gut and brain are in constant communication through the vagus nerve.
This means every gut symptom could be a brain signal—and vice versa.

How to Support Your Gut-Brain Axis Naturally🌿

If you’re experiencing brain fog, mood swings, or poor sleep, supporting your gut-brain connection is a powerful first step.
Here are my top treatments that have worked successfully with my patients:

L-Glutamine Powder – Helps heal leaky gut and calm gut inflammation

Probiotic 100 Billion – Replenishes healthy bacteria that support serotonin, dopamine, and melatonin production

Methyl B Complex – Promotes methylation and boosts serotonin and dopamine

Vitamin D3 with K2 – A longevity vitamin/hormone essential for brain and immune function

Essential Magnesium – Calms the nervous system, promotes deep sleep, and breaks down anxiety-producing neurotransmitters

Omega-3 Fish Oil – Provides brain-essential fatty acids and lowers inflammation

Phosphatidyl Serine – A brain-protective phospholipid that helps lower cortisol and improve memory

Your brain reflects the state of your gut. It’s not in your head—it’s in your gut. 
When you heal your gut—you heal your mind.
