Educational only — not a diagnosis, prescription, or lab order. goodtides is not a medical provider or laboratory. The "goodtides optimal range" is an educational target that is narrower than the standard lab reference interval; it is not a certified, guaranteed, or verified clinical threshold. Always interpret results with a licensed physician who knows your history.
