    How Do I Choose The Best Live Cultures Gummies?

    When choosing friendly bacteria gummies for your child, you want to choose a delicious gummy you know your kids will want to eat. The best children’s gummies should be made from natural ingredients, and contain a high-quality live cultures strain suitable for children. Bacillus coagulans Unique IS-2 is one of the most well-researched bacillus strains in children1,2,3 and is an ideal strain for kids’ friendly bacteria gummies.

    How Do Friendly Bacteria Gummies Work?

    Optibac Kids Gummies contain a species of friendly bacteria, Bacillus coagulans, that has the ability to form a protective layer around itself, making it highly resistant to acid, heat and the harsh conditions of the mouth and stomach5. This ensures it gets to the gut alive and starts to flourish. These children’s gummies also contain FOS fibres which increase natural gut bacteria, calcium which contributes to the normal function of digestive enzymes, and vitamin D3 which contributes to the normal function of the immune system, making these an ideal supplement for digestive and immune support.

    How Should My Child Take Live Cultures Gummies?

    Optibac Kids Gummies are chewable and easy-to-take – just one a day, with or without food. They can be given for short periods whenever you think your child needs extra support, but it’s safe, and recommended, for them to be taken daily on an ongoing basis.

    How Many Friendly Bacteria Gummies Can Kids Take?

    For children aged three years and over, one gummy per day is recommended. As these delicious gummies are taste-tested by children, you might find your child takes more than one! If so, don’t  worry, as it’s not thought to be possible to ‘overdose’ on friendly bacteria; however, in general it’s best to stick to the recommended daily dose.

    When Should Kids Take Gummies?

    When it comes to deciding the best time to take our friendly bacteria gummies, it is helpful to know Optibac Kids Gummies can be taken any time of the day, with or without food. This means you can either give them at mealtimes as part of your child’s daily health regime, or take them with you wherever you go, and give them whenever it is most convenient.

    What Is the Difference Between Gummies VS Capsules or Powder?

    Capsule and powder products usually contain strains of Lactobacilli or Bifidobacteria, whereas in our Kids Gummies we use Bacillus coagulans Unique IS-2 because it is more resilient to moisture, acid and heat, making it more suitable for use in this format. Some children love gummies, but others prefer drops or capsules, or to have their flavourless friendly bacteria powder mixed in with their yogurt or cereal. It is up to you and your child which format you prefer to take as your friendly bactieria supplement. If your child has a particular health condition, you may also like to consider which strains your supplement contains, to ensure they take the live cultures strain(s) which have been researched for that condition.


    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, children 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 diagnose, cure, treat or prevent any disease. Food supplements should not be used as a substitute for a healthy lifestyle and varied diet. If child is taking any medications or has a serious medical condition, consult a doctor before use. Optibac supplements will not cause dependency and may be used on an ongoing basis.

    • Jasper "I loved them! The taste was really good. It was really fruity." Tilda "I really like the type of jelly. It was squishy but it wasn’t *really* squishy. I really liked the flavour; It tasted like real strawberries!” With a history of Coeliac Disease in our family, gut health is particularly important to us. My 5 and 8 year olds take a daily vitamin gummy every day and a quick and easy probiotic is a brilliant addition to their morning routine to help support their digestive system. We all loved their real fruit taste and firm jelly texture.

    • Building up my children’s immunity is very important to me, but I’ve found it difficult to get them to take probiotic supplements. These gummies contain all that’s needed for good gut health as well as added vitamin D, which is also very important. The kids loved them and I had no trouble getting them to take these gummies as they had a wonderfully fruity taste with the added bonus that they were sugar free. I feel like I have finally found a probiotic gummy with which I don’t have to compromise on its contents in order to get the kids to take them.

      Chrissy- [pre-launch trial] - 23rd February 2021

    • Optibac is a perfect choice for my children's digestive and immune health. They love the strawberry taste and with the gummies being swallowable, the kids look at them as candy rather than vitamins and will remind me to give them their "treat" every morning. Unlike so many other similar products, these gummies are not covered in sugar which is an added benefit. I recommend these to all parents who have a hard time keeping their children "regular" and also for helping kids focus during home learning and boosting their immune systems before returning to school. These probiotics will definitely be beneficial to a healthy diet and lifestyle. Great product!!!
