Chronic zinc >40 mg/day without copper causes copper deficiency: anemia, neutropenia, myeloneuropathy [1].
Granulomatous diseases (sarcoidosis, TB) — unregulated extra-renal CYP27B1 can cause life-threatening hypercalcemia even at standard doses [2][21]
Sensory neuropathy from chronic high-dose B6 (>200 mg/day) — presents as numbness, ataxia. Can be irreversible. Often self-prescribed by patients for PMS or carpal tunnel [3]
Nitrous oxide anesthesia in subclinically B12-deficient patients can precipitate acute combined degeneration — always check B12 before elective procedures using N₂O [5]
Severe deficiency (<0.50 mmol/L) causes secondary hypocalcemia and hypokalemia that will not correct until magnesium is repleted first [1].
Iron supplementation in iron-replete patients may increase cardiovascular and cancer risk — always document deficiency before prescribing [1].
