A structured, pharmacist-reviewed set of plain-English education guides for 21 nutrients commonly involved in drug–nutrient depletion questions (the B-vitamins, vitamins A/C/D/E/K, magnesium, potassium, calcium, zinc, iron, CoQ10, carnitine, melatonin, sodium, copper). Each guide provides, in consumer language: what the nutrient does, common dietary sources, questions to raise with a clinician, a cautious supplementation note, and high-risk cautions (e.g. kidney disease, warfarin interaction, absorption interference). This is the first-party editorial layer behind HelloPharmacist's nutrient-depletion checker — general nutrition education written by the pharmacy team, kept deliberately separate from any licensed clinical record. Provided as structured JSON (with an alias map) and a flattened CSV. Follows fixed editorial rules: non-alarmist, no dosing advice, decisions routed back to the reader's own pharmacist or prescriber. Intended as a patient-education / health-literacy resource — not medical advice and not a clinical reference. Original content, released under CC BY 4.0.
