    How Do I Choose The Best Probiotic Gummies?

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

    How Do Probiotic 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 probiotic gummies also contain prebiotic fibers (FOS) 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 all-round gut and immune support.

    What is Bacillus coagulans good for?

    The Bacillus coagulans Unique IS-2 strain in Optibac Kids Gummies has been shown to support digestive health1,2,3,4, and immune health6.

    How Should My Child Take Probiotic 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 Probiotic Gummies Can Kids Take?

    As these delicious gummies are taste-tested by children, you might find your child wants to eat more than one! If they do, don’t worry too much - it’s not thought to be possible to ‘overdose’ on probiotics, and the added ingredients, vitamin D and calcium, have safe upper limits which are many times the levels included in our Kids Gummies. So an extra gummy or two occasionally is fine; however, in general it’s best to stick to the recommended daily dose, especially if your child takes other vitamin and mineral supplements containing vitamin D and calcium7.

    When Should Kids Take Probiotic Gummies?

    When it comes to deciding the best time to take probiotic 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 flavorless probiotic powder mixed in with their yogurt or cereal. It is up to you and your child which format you prefer to take as your probiotic supplement. If your child has a particular health condition, you may also like to consider which probiotic strains your supplement contains, to ensure they take the probiotic strain(s) which have been researched for that condition.

    • Bought from my local health store (reapers). My daughter 5 absolutely loves the taste of these. She is a super fussy eater and has very sensitive taste and smell! I’ve had liquid probiotics in the past and she hated them so to have something she enjoys really makes it so much easier as a parent trying to get the good bugs into her! I’m waiting for my 2.5tear old to turn 3 so he can start on them to! I recommend to all of my friends with children.

      Aimee youles - 25th November 2021

    • My son (age 9) is still a super fussy eater, so its really hard to find anything he will take happily. These gummies have been a hit and I know how important gut health is to their overall wellbeing and Immunity so I'm delighted that he will take them so willingly. The additional Calcium and Vitamin D is an added bonus on top of the friendly bacteria. Great product OptiBac!

      Heidi - 1st September 2021

    • I’ve don’t my research as we are supporting my eldest who has some gut dysbiosis. Optibac are recommended by all the nutritionists and natural health practitioners we have worked with, and both my kids love these new gummies. Thank you!
