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

    What are kid’s probiotics?

    Probiotics for children are dietary supplements specifically designed for infants and children. Certain species and strains of beneficial bacteria are found naturally 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 These supplements can replenish the gut with friendly bacteria, contributing to a balanced gut microbiome. The gut microbiome plays an important role in your child’s health and wellbeing3.  

    Can I, or should I, give my child probiotics?

    Research has shown that giving certain friendly bacteria strains, such as Lactobacillus acidophilus Rosell-52, Bifidobacterium infantis Rosell-33 & Bifidobacterium bifidum Rosell-71, can help support your child’s health2. These strains can be found in Optibac ‘For babies & children’, a natural, gentle probiotic supplement, suitable for early life and throughout childhood.

    How do I choose the best probiotic for my child?

    When choosing a probiotic supplement for your child, choose one which has been researched in children, and which is suitable for your child’s health requirements. Optibac ‘For babies & children’ is an award-winning probiotic supplement which has been clinically tested in hundreds of babies, and young children2,4. It is suitable for use in both formula-fed and breastfed babies. Different probiotics strains do different things, and the strains in Optibac ‘For babies & children’ are a great choice to support your child’s digestion, immune health, and overall wellbeing. 

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

    It is best to give friendly bacteria in the morning with the first meal of the day. This helps to ensure that the bacteria pass safely through your child’s tummy and into the gut.

    For how long should my child take their probiotics?

    Some parents choose to give their children a probiotic when they feel they need extra support, such as during the winter months for immune health2,4, but others prefer to include probiotics as part of their child’s daily health routine. Whether your child is 3 months old, 3 years old, or 12 years old, ‘For babies & children’ is designed for daily, ongoing use, or whenever you feel your child’s gut needs support.

    • 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!

      Rosie Sprake - 9th March 2021

    • 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.
