Gut Health & The Microbiome

Clinical Focus: Gut-Brain Axis, Microbiome Diversity & Serotonin Production

approximately 90-95% of the body's serotonin is produced in the gut. The gut-brain axis is not a metaphor — it is a bidirectional communication highway between your enteric nervous system and your brain. These products support the ecosystem that makes psychiatric treatment work.

Key Metric: For gut-brain support, prioritize strain diversity (≥ 20 strains), prebiotic fiber, and living cultures over single-strain probiotics

Clinician’s Note

Probiotics Are Not All Equal

“Most commercial probiotics are marketing exercises. The strains die in stomach acid, the CFU counts are meaningless if they don’t survive, and single-strain products miss the point. I recommend products with proven delivery technology (like Seed’s nested capsule) or living whole-food cultures that have millennia of evidence behind them.”

— Arthur J. Anderson, APRN
Clinician’s Note

The Gut-Psych Connection

“Every psychiatric medication I prescribe is absorbed through the gut. Gut inflammation impairs absorption, alters drug metabolism, and produces inflammatory cytokines that may contribute to depressive symptoms and anxiety. Fixing the gut isn’t alternative medicine — it’s foundational pharmacology.”

— Arthur J. Anderson, APRN
Evidence Guide
Strong Evidence Multiple RCTs, systematic reviews, or meta-analyses supporting clinical use.
Moderate Evidence Supported by clinical studies with promising but less definitive results.
Emerging Evidence Preclinical data or early-stage human trials showing plausible mechanisms.
