The Host Capacity Model

The Host Capacity Model is an educational systems-biology framework. It re-frames recurrent gut and immune presentations as the downstream signature of constrained host capacity — epithelial energy state, barrier integrity, and immune tone — rather than as a microbe-first problem. The model proposes that habitat conditions shape which microbes can persist. The framework is published as an open educational resource for client orientation and clinician discussion. It is not a diagnosis, does not prescribe, and does not replace licensed clinical care; it provides a structured way to read complex cases for discussion with a care team.

An educational mechanistic framework re-framing recurrent gut, immune, and post-viral patterns as a function of host capacity (epithelial energy, barrier, immune tone) rather than microbial composition alone. Intended for case discussion.

BiomeLogic Host Capacity Model: educational systems-biology framework. Hypothesis: recurrent gut/immune/post-viral patterns reflect host capacity constraints (epithelial bioenergetics, barrier, immune tone) shaping microbial habitat conditions. Not a diagnosis, not prescriptive.

The framework does not establish a single cause for any individual case, does not establish that any specific intervention will help, and is not a substitute for clinical evaluation.
