Better Sleep Starts
in Your Gut
The surprising connection between your microbiome and the neurotransmitters that control how you fall, and stay, asleep.
"A patient told me last month she had tried everything for sleep. Melatonin. Magnesium. A white noise machine that cost more than her groceries. Nothing worked until we addressed her gut."
That surprised her. It should not have. Your gut bacteria produce and regulate the same neurotransmitters your brain uses to fall asleep: serotonin, GABA, and melatonin. When your microbiome is off balance, those chemical signals get disrupted before they ever reach your brain.

Point reduction on the Pittsburgh Sleep Quality Index, the gold-standard sleep measurement tool, observed in a 2025 meta-analysis of 6 clinical trials involving 424 patients with insomnia.

A 2-point drop on the PSQI represents real, noticeable improvement in how you fall asleep and stay asleep. The probiotics also reduced depression scores. No increase in side effects.
-
Your gut bacteria metabolize tryptophan, the amino acid your body converts into serotonin and then melatonin, your sleep hormone.
-
Short-chain fatty acids produced by beneficial bacteria influence GABA production, your brain's primary calming neurotransmitter.
-
Circadian rhythm disruption from late meals, irregular sleep, or stress throws off microbiome composition, creating a feedback loop that makes sleep worse.

This is why I formulated our Synbiotic Probiotic and Prebiotic with both probiotic strains and prebiotic fiber. The prebiotics feed the beneficial bacteria so they can do this neurotransmitter work. A probiotic alone is half the equation.
Synbiotic Probiotic & Prebiotic
Both probiotic strains and prebiotic fiber. Every formula is Low FODMAP and gentle on sensitive digestive systems, because gut sensitivity compounds sleep problems.
