The Vagal Bitters Protocol™

TAS2R → Gα-gustducin → PLCβ2 → IP3 → Ca²⁺ → CCK → CCK1 receptors on vagal afferents → nucleus of the solitary tract → parasympathetic activation. An 8-to-12-minute cascade. Meyerhof (2010), Lu et al. (2017).

Any nervous system calibrated by sustained operational load — combat veterans, medicine shift-workers, single-parent caregivers, the financially precarious. Absorbs the free Vagal Reset as Phase 1.
