Irving JA, Mattman A, Lockitch G, Farrell K, Wadsworth LD. Element of caution: a case of reversible cytopenias associated with excessive zinc supplementation. CMAJ. 2003;169(2):129-31.
Zinc is a common supplement and is widely available as a standard component of many over-the-counter products. A number of reports have identified an association between excessive zinc intake and severe cytopenia. We report a case of zinc-induced copper deficiency in a young adult to illustrate this under-recognized cause of anemia and neutropenia.
