The 2017 European Food Safety Authority (EFSA) recommendation of an acceptable daily intake (ADI) of 30 mg glutamic acid/kg bw/day did not take into consideration the primary energy sources during infancy, including infant formulas. In the present study, we determined total daily intakes of glutamic acid in a contemporary cohort of healthy infants who were fed either cow milk formula (CMF) or extensive protein hydrolysate formula (EHF); the formulas differed substantially in glutamic acid content. The infants (n = 141) were randomized to be fed either CMF or EHF. Dietary intakes were determined from weighed bottle methods and/or prospective diet records, and body weights were measured on 14 occasions from 0.5 to 12.5 months. Secondary data analysis determined the glutamic acid content of the diet over time. The trial was registered at  http://www. CLINICALTRIALS: gov/ as NCT01700205, 3 October 2012. Glutamic acid intake from formula and other foods was significantly higher in infants fed EHF when compared to CMF. As glutamic acid intake from formula decreased, intake from other nutritional sources steadily increased from 5.5 months. Regardless of formula type, every infant exceeded the ADI of 30 mg/kg bw/day from 0.5 to 12.5 months.   Conclusion: Given that the ADI recommendation was not based on actual intake data of primary energy sources during infancy, the present findings on the growing child's ingestion of glutamic acid from infant formula and the complementary diet may be of interest when developing future guidelines and communications to parents, clinical care providers, and policy makers. WHAT IS KNOWN: • The 2017 re-evaluation of the safety of glutamic acid-glutamates and the recommended acceptable daily intake (ADI) of 30 mg/kg bw/d by the European Food Safety Authority (EFSA) did not include actual intake data of the primary energy sources during infancy. WHAT IS NEW: • During the first year, glutamic acid intake from infant formula and other food sources exceeded the ADI of 30 mg/kg bw/day.
