    What are baby probiotics?

    Probiotics for babies are dietary supplements that use good bacteria strains naturally present in the baby’s gut. ‘Probiotic’ means ‘for life’. The WHO defines probiotics as live microorganisms which, when administered in adequate amounts, confer a health benefit on the host. An imbalance in the good and bad bacteria in a baby's gut in the first few months of life may trigger occasional digestive upsets or gas production.

    Can or should I give my baby probiotics?

    You can give ‘For your baby’ probiotics to your newborn from birth onwards. Research has shown that giving certain probiotic strains, such as Bifidobacterium breve M-16V® to infants can help to increase levels of Bifidobacteria in the gut1,2, soothe colic2, support immune health and improve allergies3

    How do I choose the best probiotic for my baby?

    When choosing a probiotic supplement for your baby, you need to feel confident that it is safe, effective, and suitable for the infant microbiome4. ‘For your baby’ contains an award-winning probiotic strain which has been tested in over 4000 newborn infants5, babies, and young children6, and it is ideal for use in both formula and breastfed babies.

    How do I give probiotics to a breastfed baby?

    It can be tricky giving supplements to a breastfed baby, but ‘For your baby’ makes this simple. The easy-to-use dropper allows you to either gently drop the liquid into baby’s mouth, on a nipple or clean finger, give it on a spoon, or add it to cool non-acidic drink.

    When is the best time of day to give baby probiotics?

    It’s best to give probiotics in the morning with the first feed or meal of the day. This helps to ensure that the probiotics pass safely through your baby’s tummy and into the gut.

    How long should my baby take probiotics?

    So many factors affect the health and development of your baby’s gut, including birthing mode, environment and antibiotics; so supporting the microbiome in their early years can be worthwhile. Whether your baby is newborn, one month old, or one year old, ‘For your baby’ is designed for daily, ongoing use.

    Can you give a baby too many probiotics?

    Probiotics are very safe for babies and you cannot ‘overdose’, so don’t worry about giving them too much; however, there’s no reason to use more than they need. ‘For your baby’ gives the recommended dose of 1 billion live cultures in just 8, easy to administer drops.


    Live probiotic cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU (very premature babies), 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. Keep out of reach and sight of children.

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

    • I am really pleased that I came across these prebiotics!! It had never crossed my mind that these would be something that would help my baby in many ways. I tried the For Your Baby drops to see if it would help my babies trapped wind! She didny seem to suffer with anything until she was about 9 months old. We had sleepless nights for many weeks with her not settling from wind. I tried the drops and after a couple of weeks she is sleeping again, we both are!! And most importantly, she doesnt have bad trapped wind anymore and she passes it much more easily. I cant say for definate if its these drops, but I'll I'll definately be carrying on with them!

    • We have been using For your baby probiotic drops since my little one was five months old (now 11 months). We started to give them to him to help repair his gut as we identified him as having dairy and soya intolerances. Over the course of a few weeks we noticed some improvement in him being more comfortable. Although it’s hard to pinpoint the exact reason, we do feel that these drops have had a positive effect and helped him. They are really easy to give him, perfect when breastfeeding, and he enjoys taking them directly. I would recommend them to parents of babies as easy to give and it seems to help with protecting the gut and fighting bugs. Thank you to Paul and Sandra for highly recommending this brand.

    • We love this probiotic, and so does baby Jack! We give it daily and I'm really reassured that we're doing all we can to support his microbiome from the start.
