01 Why NurtureBio is different
Most products do half the job.
A developing gut needs beneficial bacteria and the right fuel to feed them. NurtureBio delivers both in one sachet.
Probiotics add beneficial bacteria
Four targeted strains, selected for the developing gut of infants and toddlers.
HMOs feed them
Human milk oligosaccharides are the special prebiotics found in breast milk. They are the fuel beneficial bacteria need to thrive.
NurtureBio combines both
Five HMOs plus four probiotic strains, together in one daily sachet.

06 Our story
Built by parents. Developed with leading infant microbiome scientists.
After five ear infections and five courses of antibiotics, our child developed severe GI issues. We tried single-strain probiotics, personalized probiotics, fiber gummies, and laxatives. Our child finally found relief after we combined HMOs with probiotics.
We built the product we wished had existed.
