Correcting zinc deficiency in nursing home residents: a randomized trial comparing 30 and 60 mg/day elemental zinc supplementation

Introduction

Low serum zinc is associated with higher pneumonia incidence and illness duration compared to individuals with adequate serum zinc levels. However, the optimal and safe zinc supplementation dose to correct deficiency has not been established. This study aimed to determine the optimal and safe dose of elemental zinc supplementation to correct deficiency in older adults residing in nursing homes.
