The Gut-Brain-Sleep Axis Explained
Microbiome’s Role in Sleep Regulation
Serotonin Production Pathways
90% of serotonin (melatonin precursor) originates in the gut.
Inflammatory Markers Impact
Dysbiosis increases cytokines that fragment sleep architecture.
Sleep-Disrupting Digestive Issues
GERD and Sleep Fragmentation
Acid reflux causes micro-awakenings throughout the night.
SIBO and Restless Sleep
Bacterial overgrowth correlates with increased limb movements.
Nutritional Strategies for Dual Optimization
Probiotic and Prebiotic Synergy
Fermented Food Timing
Consume kefir and kimchi at lunch for maximal GABA conversion.
Resistant Starch Benefits
Cooled potatoes and green bananas feed sleep-promoting bacteria.
Circadian Fasting Protocols
13-Hour Overnight Fast
Aligns gut microbiome rhythms with sleep-wake cycles.
Morning Sunlight Exposure
Triggers gut clock genes that regulate digestive timing.
