Impact of Higher Zinc Supplementation on Neonatal Weight Velocity

Preterm infants are at increased risk for micronutrient deficiencies due to limited in utero nutrient accretion, immature gastrointestinal absorption, and increased postnatal nutritional requirements. Zinc is a critical trace element involved in cellular growth, protein synthesis, and hormonal regulation, all of which are essential for postnatal growth and development. Present recommendations suggest zinc supplementation of 1-3 mg/kg/day. However, this dosing range is not well established with some clinical trials using 10 mg/kg/day. This study examines the effects of zinc supplementation (1 vs 3 mg/kg/day) on weight velocity in preterm infants.
