    Customer Questions

    All questions answered by Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    Can you give a child too many friendly bacteria?

    Live cultures are very safe for children1,2 and it's not thought to be possible to ‘overdose’ on them, so don’t worry about giving your child too many. However, there’s no reason to use more than they need and in general, it is best to give them the recommended dosage. Optibac Babies & Children provides the recommended daily dose of 3 billion live cultures per sachet.

    Is Optibac Babies & Children a vegetarian supplement?

    Yes, Optibac Babies & Children is vegetarian. There is no dairy present at any stage of the manufacturing, the probiotic strains are vegan but the added Vitamin D3 is vegetarian. It is also gluten-free.

  • How To Use


    • Best taken with a meal, preferably with breakfast
    • Simply mix with your child's favourite cool, non-acidic foods or drinks – try sprinkling the powder over cereal, mixing it with yogurt, or dissolve in water or 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 1 sachet daily.
    • If desired or professionally directed, can be increased to 2 sachets a day

    Customer Questions

    All questions answered by Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    What are children’s friendly bacteria?

    Live cultures for children are dietary supplements specially designed for use by infants and children. Certain species and strains of bacteria are more commonly found in a child’s gut, such as strains of Bifidobacteria and Lactobacilli. High-quality kids’ supplements will contain live cultures which have been clinically researched in children and are particularly suitable for a child’s developing digestive system. Optibac Babies & Children contains strains of Bifidobacteria and Lactobacilli which have been researched in children, such as Bifidobacterium breve M-16V ® and Lactobacillus rhamnosus GG.

    How do I choose the best friendly bacteria supplement for my child?

    When choosing a friendly bacteria supplement for your child, you need to feel confident that it’s safe, well-researched, and contains bacteria which are suitable for your child's needs. It's best to choose a supplement which has been specifically researched and designed for kids. Optibac Babies & Children is a high-quality live cultures supplement. Collectively these 3 strains have been clinically tested in thousands of babies and children1,2,3,4,5.

    When is the best time of day to give Optibac Babies & Children?

    If possible it is best to give Optibac Babies & Children in the morning with the first meal of the day. This is when stomach acidity is at its most neutral, ensuring that the live cultures pass safely through the harsh stomach environment. Giving the supplement with food also helps to buffer stomach acid and helps to assist the transit of the bacteria through the stomach and into the gut.


    Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

    This is a food supplement and is not intended to prevent, treat or diagnose any medical conditions. Probiotic supplements should not be used as a substitute for a healthy lifestyle and varied diet. If you are taking any medications or have a serious medical condition, consult a doctor before use. Optibac Probiotics supplements will not cause dependency and may be used on an ongoing basis.

    • 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.

    • Excellent product!

      stela - 22nd July 2021

    • This is such a fabulous product. Having tried various other probiotics this is by far the best we have used. Our 5 year old daughter didn't notice it in her cereal at all and once she did spot me adding it to her cereal, she now refers to it as 'the magic powder' and asks for it to be added! I would highly recommend to anyone considering purchasing!
