Three decades of microbiome research have produced substantial evidence linking microbial composition to neurological, metabolic, and psychiatric outcomes. That evidence remains fragmented across thousands of siloed studies, unresolved at the strain-specificity level required for clinical application. NEXOBI ingests the full corpus, maps it mechanistically, grades it by study design, and resolves conflicts transparently — producing auditable, strain-specific recommendations simultaneously at research, clinician, and layman depth.
