- Support cognitive, motor, and communication skills through 5 years of age8||
A proprietary HuMO6™§ immune and gentle blend including 2’-FL HMO and a patented dual prebiotic blend of GOS and PDX, designed to support a baby’s immune and gut health:
- Infant formula that has a combination of GOS and PDX has been shown to support immune health by promoting the growth of beneficial bacteria (bifidobacteria and lactobacilli)9-10
- Infant formula that has a combination of GOS and PDX has been shown to promote soft stools similar to those reported for breastfed infants11
- Infant formula that has a combination of GOS and 2’-FL HMO has been associated with a 66% reduction in respiratory infections, based on a parental report in a post-hoc analysis.12
- Infant formula that has partially hydrolyzed protein and a combination of GOS and PDX has been shown to promote softer, more frequent stools within 1 week in infants with difficult stooling.13§
Additional product features:
- Non-GMO#
- Kosher Dairy (OU-D), Halal
- Inositol at the average amount found in breast milk♠
*Study conducted prior to the addition of PDX, GOS, and milk fat globule membrane (MFGM) in the Gentlease® formula. Among infants identified as very or extremely fussy by parent report receiving a full-lactose cow’s milk protein formula for 7 days prior to enrollment, as compared with baseline.
†Comparison based on whey:casein ratio of typical mature breast milk (15 days to 6 months after birth).14
‡Studies compared infants fed Enfamil® that had DHA and ARA vs. discontinued Enfamil without DHA and ARA; studied before the addition of prebiotics.
§As indicated by Bayley-III cognitive, language and motor scores at 12 months in a study of a different formula with MFGM and lactoferrin added as ingredients compared to a standard formula without.
||As indicated by WPPSI-IV, tested at 5.5-6 years of age
¶Compared with a non-hydrolyzed formula that had PDX and GOS.
