Four probiotic strains

Five HMO prebiotics

Made for birth to 48 months

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.

Visit the full FAQ
If 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.
