N-of-1 Self-Experimentation Platform for Gut-Brain Protocols

C5/10March 12, 2026
WhatA structured self-tracking app that lets individuals run personal experiments with gut-health interventions (capsaicin, fiber, probiotics) and measures cognitive outcomes over time.
SignalMultiple commenters express frustration that institutional research moves too slowly and that individuals should take gut-brain optimization into their own hands — there is a strong DIY biohacker demand for tools to do this rigorously rather than anecdotally.
Why NowWearables now track cognitive proxies (sleep architecture, HRV, reaction time), at-home microbiome testing is cheap, and the quantified-self community has matured enough to adopt structured protocols.
MarketBiohackers and health-optimizers (10M+ globally), aging knowledge workers worried about cognitive decline; competes with Levels and InsideTracker but none focus on gut-brain self-experimentation.
MoatAggregated anonymized n-of-1 trial data across thousands of users creates a unique real-world evidence dataset that no academic lab can match in scale or diversity.
