GABA is your nervous system's main 'brake.' Our formulary maps NDI (neurobiome-directed intervention) strains — including L. plantarum — to GABA and serotonin signalling, and our condition model links the gut directly to a full NEURO stress-response system (HPA axis, cortisol, hypervigilance).
The gut–anxiety loop
Gut microbes help regulate GABA, serotonin, and the vagus nerve — the circuitry behind the stress response. When the microbiome is disrupted, that brake can weaken. This is why our condition system views anxiety, chronic stress, and HPA-axis dysregulation as gut-connected, not purely 'in your head.' Flore's formulas support everyday calm; they are not a treatment for an anxiety disorder.
What we map, and why personalized
Instead of one 'calm' pill, Flore reads your microbiome and selects the NDI strains your gut actually needs. The research here is still emerging — we're honest about that — but the mechanism (microbiome → GABA/serotonin → calmer signalling) is well supported, and precision is how Flore acts on it.
