Summary
Zinc and green tea supplementation have both been independently studied for supporting immune
health during cold and flu-like illness in non-hospitalized patients with clinical trials
demonstrating promising but inconsistent results. Combination therapy may offer an improved
effect as the antioxidant compounds found in green tea have been shown to increase cellular
zinc concentrations thereby inhibiting viral replication. This study seeks to evaluate the
effect of combination supplementation using established doses of zinc and green tea extract
on symptom duration and severity from cold and flu-like illness, including COVID-19, in adult
community patients enrolled in a randomized placebo-controlled trial.
