Their gut is still growing into its own.
As your little one grows and feeding changes, the community of bacteria in their gut changes too. A synbiotic brings probiotics and prebiotics together. Here’s why each is part of NurtureBio’s early-life formula.
Probiotics
The beneficial bacteria
NurtureBio includes B. infantis and B. bifidum, species associated with the infant gut, alongside L. reuteri. Four named strains, with 3 billion CFU in the combined blend.
HMO prebiotics
Nourishment for beneficial bacteria
HMOs are a type of prebiotic naturally found in human milk. NurtureBio includes five HMO ingredients that help nourish beneficial gut bacteria.
Together in one daily sachet. That’s NurtureBio’s synbiotic.

A few good questions.
For the details you want before adding something new to their day.
Visit the full FAQIf I take a probiotic, does my child need one too?
Not necessarily. Your own routine doesn’t establish that your child needs a supplement. Talk with your child’s pediatrician about their age, diet and health, especially for a premature baby or a child with a medical condition.
Why choose a synbiotic?
A synbiotic combines probiotics and prebiotics. NurtureBio pairs four probiotic strains with five HMO prebiotics, so both are part of the same daily sachet.
Can I use it with breast milk, formula or food?
NurtureBio’s directions allow mixing with expressed breast milk, formula or an age-appropriate soft food. Use room-temperature or slightly warm feeds, never hot, and follow the current package instructions.
What if my child has a milk allergy?
NurtureBio’s FAQ states that milk is declared on the label. Review the full current ingredient and allergen label with your pediatrician before use if your child has a milk allergy.
Does it need to stay in the fridge?
No refrigeration is needed. Follow the storage instructions on your box.
Do I have to subscribe?
No. A one-time box is $59.00 USD. With a subscription, your first box of 30 daily sachets is $29.59 USD (about 50% off), applied automatically in cart. Your plan then renews at $50.15 USD every 4 weeks. You can skip or cancel anytime.
