Bifidobacteria, in particular, are key colonizers of a baby's colon. B. infantis is the only bacteria capable of using all the unique sugars in breast milk to release the milk's full benefits and optimally support development of the brain, intestines, and immune function. Jarro-Dophilus® Baby also contains clinically documented Lacticaseibacillus strains that synergistically support immunity and healthy digestive function. Jarro-Dophilus Baby powder includes BimunoⓇ GOS (Galactooligosaccharides), a prebiotic fiber. BimunoⓇ GOS contains oligosaccharides (complex sugars) similar to those in human breast milk and shown to selectively feed infant-associated bifidobacteria.
