The Method
Built for the
complicated
body.
Most nutrition apps count calories. 404. reads your medical reality. Upload bloodwork, genetic panels, wearable data, diagnoses and treatment protocols — and every product you scan is graded against the one stack that matters: yours.
Backed by a board of functional, integrative and chronic-care physicians. Engineered with the discipline of a clinical lab — not the noise of a wellness feed.
