  • How To Use


    • Best taken with a meal, preferably with breakfast.
    • Simply mix with your child's favorite foods or drinks - sprinkle the powder over cereal, mix in with yogurt or dissolve in water or cold milk.
    • Can be taken with formula milk - simply add to the bottle once it has cooled down to room temperature (as heat reduces the viability of natural bacteria).
    • For breastfed babies, powder can be applied to nipple or clean finger for baby to suckle.

    Recommended amount

    • Give one sachet daily.
    • If desired or professionally directed, can be increased to 2 sachets a day.

    Customer Questions

    All questions answered by Dr. Kate Stephens PhD (Food and Microbial Sciences) BSc(Hons) Medical Microbiology and probiotic expert Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    Can you give a child too many probiotics?

    Probiotics are very safe1,2 and you can’t ‘overdose’ on them. But in general, it's best to stick to our recommended daily amount of 1-2 sachets - especially if your child takes other vitamin supplements containing Vitamin D – keep an eye on their daily Vitamin D intake. If you have any concerns, please contact our nutrition team.

    Is Babies & Children a vegetarian supplement?

    Yes, Optibac Babies & Children is vegetarian, and it’s also gluten and dairy-free. There is no dairy present at any stage of the manufacturing, and the live cultures strains are vegan, but the added Vitamin D3 is vegetarian.

    Is Optibac Babies & Children a good alternative to Biokult Infantis?

    If you were previously using BioKult Infantis, you will know it has been discontinued. Fortunately, we’ve got you covered! Optibac Probiotics Babies & Children is an ideal BioKult Infantis alternative. Like BioKult Infantis, Babies & Children probiotic sachets contain added Fructooligosaccharide (FOS) fibres to maintain natural gut bacteria, and Vitamin D to support immune health. But unlike BioKult Infantis, Optibac Babies & Children is dairy-free, vegetarian, and contains the world's most researched live cultures strain6, Lactobacillus rhamnosus GG, extensively studied in infants and children.

    • Bought this to try and see if it would help my daughter (given antibiotics at birth, reflux until 8 months and still vomitting every other week or so at 2 years old - unfortunately not given much help from gp) as I suspect that antibiotics given to a newborn don't bode well for long term gut health - and saw this to be the case myself. She's been taking this now for a month and a half and I can say it has helped a LOT. She has only been sick twice in that period of time which is a huge improvement from where we were, and more than anything, I feel good in knowing we are potentially restoring some of what was lost so early on in her life. If your little one has had an antibiotic treatment I really recommend giving this a try.

    • Since my older daughter was born 7yearsagain, I started to buy this product; they work so well. I'm feeding my second daughter with this product again.

    • Totally love this product, I have both my children on these probiotics my eldest boy being 6 and my youngest girl being 9 months. It supports both of them with immunity and helps my little girl with wind after her bottle. I put the powder in her last bottle at night and she sleeps through contently. When I have run out previously she has woken several times so I know they must be helping her stomach.
