  • How to use

    Instructions for use

    Food supplement suitable for infants (from birth) and children up to 12 years old.


    • Simply mix with your child's favourite foods or drinks - sprinkle the powder over cereal, mix in with yoghurt or dissolve in a glass of 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.
    • Adults & children should ideally drink plenty of water during a course of live cultures.
    • Best taken with a meal, preferably with breakfast.

    Recommended amount:

    • Infants from birth to 3 years: 1 sachet per day
    • Kids 4 - 12 years: 1 to 2 sachets per day as desired
    • Pregnant and breastfeeding mothers: 1 sachet per day

    5 Easy Ways To Take For Babies & Children:


    'For babies & children' does not require refrigeration and sachets can be used on the go. Store in a cool, dry place below 25°C and out of direct sunlight.


    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, infants with short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care.

    Food supplements should not be used as a substitute for a healthy diet and lifestyle. Those with serious medical conditions should consult their doctor before use. OptiBac will not cause dependency, and may be used on an ongoing basis.

    • Both our children (1 and 3yrs) love having these in a bit of milk after their porridge in the morning. We think these are a really important part of growing and staying healthy.

      Charles - 18th September 2020

    • Since giving my daughter OptiBac 5 months ago, I highly recommend and can’t praise these enough.

      Katie m - 2nd April 2020

    • My eldest has been taking these for a couple of years. It has definitely helped his immune system. The condition of his skin is improved (he has eczema). I started taking these after my youngest son was born. He's breastfeeding. What a difference they've made! We now have a happy baby and enjoyable evenings again! I seriously can't recommend these highly enough. Thank you OptiBac!
