How Your Gut Talks to Your Brain: And Why It Matters For Mental Health

Lumati's Take: The gut hosts a complex ecosystem of microbes that aid digestion, send signals to the brain, shape stress responses, and influence mood. This two-way communication system, known as the gut–brain axis (GBA), is a fascinating discovery in modern health science.

The Role of Gut Microbiota

The gut houses trillions of microbes (Turnbaugh et al., 2007). Their role is to:   

• Break down carbohydrates and fibers (Flint et al., 2012).   

• Synthesize vitamins (B-vitamins, vitamin K) (LeBlanc et al., 2013).   

• Produce SCFAs like butyrate, reducing inflammation (Koh et al., 2016).   

• Generate neurotransmitter precursors affecting brain signaling (Sharon et al., 2016).

Serotonin and Mood

90% of serotonin is produced in the gut by enterochromaffin cells (Yano et al., 2015).

Gut microbes influence mood by:   

• Regulating tryptophan availability for brain serotonin synthesis (O’Mahony et al., 2015).   

• Modulating inflammation, lowering serotonin/dopamine signaling (Miller & Raison, 2016).   

• Communicating via the vagus nerve to influence stress resilience (Bravo et al., 2011).

Why It Matters for Mental Health

• Dysbiosis is linked to depression and anxiety (Kelly et al., 2016).

• Psychobiotics (probiotics/prebiotics) may reduce stress and mild depressive symptoms (Sarkar et al., 2016).

• Gut barrier dysfunction and inflammation can worsen mood disorders (Foster et al., 2017).

• Lifestyle interventions—fiber, fermented foods, stress reduction—support gut and mental wellbeing (Clapp et al., 2017).

Lumati’s Role in Supporting the Gut–Brain Axis

• Lumati therapies help the gut and brain work together.

• Promote microbiome balance, reduce inflammation, and support resilience.

Lumati Red, Lumati Gold, and Eight Hours Sleep

• Standard curcumin isn’t well absorbed.

• Lumati uses nano-curcumin plus Vitamin D, B12, and iodine.

• Stacked to calm gut inflammation and support neurological health.

Red Light+ Therapy

• Standard panels use limited wavelengths.

• Lumati Red Light+ uses 10 wavelengths (blue to near-infrared).

• Provides deeper penetration, reduces inflammation, and balances microbiome.

Hydrogen Inhalation Therapy

• Hydrogen is a potent antioxidant that crosses membranes and the blood–brain barrier.

• Lowers oxidative stress and inflammation.

• Lumati generators provide consistent, medical-grade therapy.

The Takeaway

Mental health isn’t just shaped by the brain—it also depends on the gut, the immune system, and the microbiome.
