When routines change, little tummies can change too.
A baby or toddler's digestion can change during feeding transitions, after antibiotics, while introducing solids, during travel, or when the daily routine shifts. NurtureBio provides consistent daily support for the developing gut microbiome.
NurtureBio is designed for consistent daily microbiome support. It does not act like a laxative or promise immediate relief.

Built by parents who lived this
After our child developed five ear infections in five months, they received a different course of antibiotics each month. The infections cleared, but afterward our child struggled with chronic constipation.
We tried everything we could find: single-strain probiotics, personalized probiotics, fiber gummies, and laxatives. Nothing provided lasting relief. Then we learned about human milk oligosaccharides, the prebiotics that nourish beneficial bacteria in the infant gut, and began pairing HMOs with our child's probiotics. That was when our child finally found relief.
The experience showed us what had been missing: a product that combined infant-focused probiotics with the HMOs designed to nourish them. So we built the product we wished had existed for our family.
HMOs feed the bacteria your baby's gut is trying to grow.

Five HMOs and four probiotics, designed to work together.

- B. infantis Rosell-33

HMOs provide the prebiotic component. The probiotic strains provide beneficial bacteria. NurtureBio combines both in one daily synbiotic.
What HMOs do
Human milk oligosaccharides are special carbohydrates naturally abundant in breast milk. Babies digest very little of them directly. Much of their value comes from acting as a prebiotic food source that nourishes beneficial bacteria in the developing gut.
What the probiotic strains do
The four strains are bifidobacteria and lactobacilli commonly associated with the infant gut. They provide beneficial bacteria that the HMOs are suited to feed, giving both sides of a synbiotic in one sachet.
Where the HMOs come from
NurtureBio's HMOs are produced through precision fermentation and are not extracted from human breast milk. Milk is listed as an allergen because the process begins with milk-derived lactose; the finished HMOs do not contain milk protein.

Common questions from parents
Can NurtureBio help support healthy stool regularity?
NurtureBio is a daily synbiotic made to support a balanced gut microbiome and comfortable digestion, which includes support for healthy stool regularity. It is not a laxative and is not a treatment for constipation.
Is NurtureBio a laxative?
No. NurtureBio is a daily nutritional supplement designed for consistent microbiome support. It does not act like a laxative and does not promise immediate relief.
How is a synbiotic different from a probiotic?
A probiotic provides beneficial bacteria. A synbiotic combines those bacteria with a prebiotic food source. NurtureBio pairs four infant-friendly probiotic strains with five human milk oligosaccharides in one sachet.
What ages is NurtureBio made for?
NurtureBio is made for babies and toddlers from birth through 48 months.
How do I give it to my baby?
One premeasured sachet per day, mixed into a small amount of breast milk, formula, water, or soft food, according to package directions.
Can I mix it with breast milk or formula?
Yes. NurtureBio mixes into breast milk, formula, water, or soft food and works with breast, bottle, or combination feeding.
Can I use it while my child is taking antibiotics?
Many families use NurtureBio during or after a course of antibiotics as daily microbiome support. Follow your pediatrician's guidance.
How long should my child take it?
NurtureBio is designed for consistent daily use. Every child is different, so there is no fixed timeline. Many families use it as ongoing daily support.
Why is milk listed as an allergen?
Milk is listed as an allergen because the precision fermentation process used to make the HMOs begins with milk-derived lactose. The finished HMOs do not contain milk protein.
When should I call my pediatrician?
Contact your pediatrician if constipation is persistent or painful, or if it is accompanied by blood in the stool, fever, vomiting, poor feeding, signs of dehydration, or a sudden change in behavior. NurtureBio is not a substitute for medical care.
