Long-term effects of neonatal glutamine-enriched nutrition in very-low-birth-weight infants

Several studies in very-low-birth-weight (VLBW) infants have investigated the effect of parenteral or enteral glutamine supplementation on morbidity, mortality, and outcome in the neonatal period. No evidence of toxicity of glutamine supplementation was found in these clinical trials, but the results for efficacy on a limited number of outcomes have been mixed. The use of glutamine supplementation in VLBW infants has not become routine. Some authors suggest that further study in this area is no longer warranted. In this review, more recent research in the area of glutamine supplementation is described, which suggests additional studies are warranted
