What this is
Sex/age-aware banding (low / borderline / normal / high), plain- language meaning per band, intake-aware context (heavy menses + low ferritin reads differently from heavy training + low ferritin), and a link to existing supplements gated by that marker.
What this isn’t
Not a diagnosis, not a substitute for your clinician’s reading. The bands are conservative defaults; your laboratory’s reference range and your clinician’s judgement always win. The aim is to help you walk into a visit better prepared, not to interpret results yourself.
