Zinc is able to inhibit coronavirus replication and may have some therapeutic benefit if administered early in the infection.[i] Zinc may also be efficacious as adjuvant therapy to chloroquine-based drugs which help increase intracellular zinc where zinc, in turn, drug efficacy. However, long-term high-dose zinc is not recommended due to potential side effects including copper deficiency, anemia, reduction of HDL, and potential genitourinary consequences.[ii]

A 2000 randomized double-blind placebo-controlled trial involving 48 subjects evaluated the effect of ~80 mg of elemental zinc on cold symptom duration. A dose of 12.8 mg of elemental zinc in the form of zinc acetate lozenges was taken every 2-3 hours while awake for 4-5 days. The supplemented group experienced significantly fewer days with symptoms, with an average duration of 4.5 days versus 8.1 days in the unsupplemented group.[iii]

Pay close attention to zinc competency when evaluating risk or severity of COVID-19.
