Product Description
You dial in your own nutrition, recovery, and gut health. Your kids deserve the same attention. A child's gut microbiome develops rapidly in the first years of life — and getting the right bacteria in place early supports healthy digestion, a stronger immune system, and better overall resilience. Optibac Probiotics Babies & Children is a thoughtfully formulated daily probiotic sachet built specifically for that developing system, from birth through age 12.
Most probiotic supplements are made for adults. This one is formulated exclusively for children, using three of the most scientifically researched bacterial strains in pediatric nutrition — each specifically studied in infants and young children. The formula centers on Lactobacillus rhamnosus GG, the most scientifically studied probiotic strain in the world, alongside Bifidobacterium breve M-16V® and Lactobacillus rhamnosus HN001 — strains clinically researched in thousands of babies and children across peer-reviewed trials.
Strains Specifically Researched for Children – The three strains in this formula have been studied specifically in pediatric populations, not adapted from adult research. L. rhamnosus GG and B. breve M-16V® are each backed by published clinical data in infants and school-age children, making this one of the most evidence-based children's probiotic formulas available.
Added Vitamin D3 for Immune Support – Each sachet delivers 100IU (2.5mcg) of Vitamin D3 — 50% of the recommended daily intake for children — alongside the probiotic blend. Vitamin D is critical for immune function in developing children, and combining it with targeted gut bacteria provides dual-layer daily support.
Prebiotic FOS to Grow Natural Gut Bacteria – Each sachet also contains 0.5g of prebiotic FOS fiber, which acts as food for the beneficial bacteria already present in your child's gut. It's not just adding good bacteria — it's creating the environment for them to thrive.
The sachet format makes it easy to work into any routine — stir it into milk, yogurt, or cool food. Flavorless, with no added sugar, no artificial colors or flavors, no dairy, no gluten. Safe from birth through age 12, and suitable for use during pregnancy and breastfeeding.
How to Use Optibac Probiotics Babies & Children
Infants (birth to 3 years): One sachet daily mixed into milk or food, preferably with breakfast when stomach acidity is at its lowest.
Children (4 to 12 years): One to two sachets daily mixed into food or a cool non-acidic drink with breakfast.
Pro Tip: Mix into lukewarm or cool food only — heat destroys live cultures. Yogurt, oatmeal, or a smoothie all work well. Consistency matters more than timing; build it into the same meal every day.

Optibac Probiotics Babies & Children FAQ's
Everything you need to know about Optibac Probiotics Babies & Children.
Once daily, preferably with breakfast or the first feed of the day — that's when stomach acidity is closest to neutral and the live cultures have the best environment to survive. Sprinkle the sachet contents into cool, non-acidic food or drink and swirl to dissolve — don't use a spoon, as this causes the powder to clump. Children aged 4 to 12 can take one to two sachets daily if desired or professionally directed.
From birth through 12 years old — the formula is specifically designed for that full range. Infants from birth take one sachet daily mixed into milk or food. Children from 4 to 12 can increase to two sachets daily. It's one of the only probiotic supplements with strains clinically trialled across the entire infant-to-child age range.
LGG is the most researched friendly bacteria strain in the world — full stop. It's been clinically trialled in thousands of infants and school-aged children specifically, which is what makes it the right strain for a children's formula rather than a generic adult probiotic strain repurposed for small bodies. This is the strain pediatric research keeps coming back to.
Because most children are deficient in it and it directly supports immune health — the immune system literally cannot function properly without adequate Vitamin D. Each sachet delivers 2.5mcg (100IU), covering 50% of the recommended daily intake. For parents already looking at probiotic support for their child's gut and immune health, having Vitamin D built in is one less thing to manage separately.
FOS — fructooligosaccharides — is the prebiotic fiber that feeds the beneficial bacteria already in your child's gut, helping them grow and establish more effectively. At 0.5g per sachet it's a gentle, child-appropriate dose that increases natural gut bacteria without causing the digestive adjustment some adults experience with higher FOS doses.
