Optibac Babies & Children is an ideal alternative to children’s supplements such as BioKult Infantis. Whilst both supplements contain added Fructooligosaccharide (FOS) fibres to increase natural gut bacteria and come in a powder format for easy use, Optibac Babies & Children contains the world's most researched live cultures strain1, Lactobacillus rhamnosus GG, extensively studied in infants and children as well as Vitamin D to support immune health.
