Clinical Study
EFFICACY OF A PRE-THICKENED INFANT FORMULA IN INFANTS WITH GER
Clinical Study
Footnotes:
†Regurgitation formula is defined as a rice-thickened formula.
‡Based on a published, double-blind, randomized, controlled trial of Enfamil A.R. with infants who spit-up frequently (5 or more spit-ups per day) comparing frequency and volume of spit-up after feeding Enfamil A.R. to the same infants at the beginning of the study.
§Studies compared infants fed Enfamil® with DHA and ARA vs. discontinued Enfamil without DHA and ARA; studied before the addition of prebiotics.
||Each scoop adds about 0.2 fl oz to the amount of prepared formula.
Enfamil A.R. is designed to provide a sole source of nutrition for infants up to age 6 months and provide a major source of nutrition until 12 months.
