This is my favourite for my son. I love the added vitamin D and that it can be taken alongside multivitamins. No added sugars which can be hard to find in other brands!

  • 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!

The best children’s probiotic gummies should be made from natural ingredients, and contain an appropriate high-quality strain such as Bacillus coagulans Unique IS-2, which is one of the most researched Bacillus strains for gut health in children(1,2,3). Finally, you should choose delicious kids live cultures your children will actually want to eat!

Like kids’ probiotics in drops or sachets, kids' probiotic gummies support your child’s natural gut microbiome. But gummy production requires robust bacteria like B. coagulans, which form a protective layer against heat, and also against harsh stomach acid. This means they’re extra hardy(1), so can be taken with or without food at any time of day, and they’ll survive to reach the gut alive. In Optibac Kids Gummies, B. coagulans Unique IS-2 is combined with FOS fibres, vitamin D, and calcium for all-round digestive and immune support.

If your child sneaks an extra delicious gummy or two, don’t worry! It’s not thought possible to ‘overdose’ on probiotics. Optibac Probiotics Kids Gummies also contain Vitamin D and Calcium, but at levels much lower than the safe upper limits. Ideally, however, it’s best to stick to the recommended daily dose, especially if your child takes other vitamin and mineral supplements containing Vitamin D(1) and Calcium.

Capsules and powders usually contain strains of Lactobacilli or Bifidobacteria, whereas gummies use hardy Bacillus coagulans probiotic strains which can withstand the heat and moisture involved in production. Some children love gummies; others prefer drops or powder mixed in with their milk, yogurt or cereal. If you buy from a trusted brand like Optibac Probiotics, all formats will be high quality, just choose the one which suits your child best. If your child has a health condition, you may also like to consider supplements containing probiotic strains which have been researched for that condition.

You may just want to give your kids probiotic supplements whenever they need some extra oomph, but if you give Optibac Probiotics Kids Gummies, they may ask to take them every day! If so, it’s perfectly safe to do so, in fact it’s highly recommended to give children live cultures on an ongoing, daily basis, for all-round immune and digestive support*.
