Zinc deficiency is frequent in the elderly and leads to changes similar to those that occur in oxidative inflammatory aging (oxi-inflamm-aging) and immunosenescence. The possible benefits of zinc supplementation to enhance immune function are discussed. Keywords: zinc, aging, immunosenescence.
Chronic toxicity may result in copper deficiency and may cause nerve damage. Diagnosis of zinc toxicity is usually based on the time course and a history of exposure. Treatment of zinc toxicity consists of eliminating exposure to zinc; no antidotes are available.
Toxicity is rare. Ingesting doses of elemental zinc ranging from 100 to 150 mg/day for prolonged periods interferes with copper metabolism and causes low blood copper levels, red blood cell microcytosis, neutropenia, and impaired immunity; higher doses should be given only for short periods of time and the patient followed closely.
