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!

The best children’s friendly bacteria gummies are made from natural ingredients with no added sugars or sweeteners, and contain an appropriate scientifically researched live cultures strain such as Bacillus coagulans Unique IS-2, which has been extensively researched in children 1,2,3. You should also choose delicious kids live cultures gummies your children will actually want to eat! Optibac Kids Gummies are taste-tested by children, plus unlike other kids gummies they come in 100% plastic free packaging.

Like kids’ friendly bacteria in drops or sachets, kids' friendly bacteria gummies complement 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 acid1,2,3. This means your child can take them 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.

One a day is the recommedation, but if your child sneaks an extra delicious gummy or two, don’t worry! It’s not thought possible to ‘overdose’ on friendly bacteria. Ideally, however, it’s best to stick to the recommended daily dose, especially if your child takes other vitamin and mineral supplements containing Vitamin D1 and Calcium.

It is perfectly safe to take Kids Gummies alongside other multivitamin products. For Vitamin D, the general guidelines are a safe upper limit of 50 mcg (2000 IU) daily for children aged 1-101. Each Kids Gummies supplement contains 5µg of Vitamin D3 and 120mg of Calcium. For children aged 1–8 years the upper limit for Calcium is 2,500 mg per day.

To make life easy, Optibac Kids Gummies can be taken at any time of the day, with or without food, no refrigeration required. Just one chewable, delicious, easy-to-take daily gummy. Simple!

Capsules and powders usually contain strains of Lactobacilli or Bifidobacteria, whereas gummies use hardy Bacillus coagulans strains which can withstand the heat and moisture involved in production. Some children love gummies; others prefer drops or powder mixed in with milk, yogurt or cereal. If you buy from a trusted brand like Optibac, 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 live cultures which have been researched for that condition

You may want to give friendly bacteria supplements to your child whenever they need some extra oomph, but if you give Optibac 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 friendly bacteria on an ongoing, daily basis, for all-round immune^ and digestive* support.
