Optibac Babies & Children was made specifically for children and is well-liked by both parents and children. Lactobacillus rhamnosus GG®, regarded to be the most scientifically investigated strain of friendly bacteria in the world, Bifidobacterium breve M-16V®, and L. rhamnosus HN001 are the three strains of natural friendly bacteria in our new formulation. Furthermore, Babies & Children now includes vitamin D3, the most desired added component among parents polled, to help preserve immunological function. Because the stomach contains 70% of the immune system, this is an ideal supplement for your children. Each sachet contains 3 billion live microorganisms, 2.5mcg of vitamin D3, and 0.5g of FOS fibres (Fructooligosaccharides) to enhance natural gut flora, and is guaranteed until the end of the expiry date.
