🟢stack_analyze(age, sex, life_stage, detail, lang, ...)
Check a list of dietary supplements for a person: per-nutrient daily totals against NIH upper limits (UL) and RDA/AI, which products overlap, what each UL protects against, and single-product changes that would bring an above-UL nutrient back under it. Products can be given as names ("Centrum Silver Women 50+"), barcodes, DSLD IDs, or custom ingredient lists; optional candidates are evaluated as additions. Pass the person's medications and conditions (smoker, kidney_disease, hemochromatosis, lab_test_soon, cancer_treatment) to check them against the interactions in the NIH fact sheets. Returns agent_summary (plain sentences to relay), resolutions, suggestions, interactions, nutrient_totals and data_gaps. Label data only; food is included only with diet "typical".
