Gerber Good Start GentlePro Infant Formula is the first and only infant formula with 2'-FL HMO (Human Milk Oligosaccharide - not from human milk; a prebiotic just like one of those found at significant levels in breastmilk) and everyday probiotics to help support a healthy digestive tract and promote soft stools. This unique formula is also the only powder infant formula with a blend of DHA, prebiotics, and probiotics which are important components found in breastmilk, and it also contains comfort proteins (small proteins that are easy for tiny tummies to digest) and expert-recommended DHA to support brain and eye development.
