 The probiotic used in this study is a sub-species within a family of ‘good’ bacteria called Bifidobacterium . This bacterium has historically been found in very high numbers in the gut microbiome of breastfed infants but is now missing from the gastrointestinal tract of most infants in the industrialized world. There is evidence to support that this probiotic supplementation may establishing and assist in maintaining a healthy gut composition.

What is a Baby Brezza?

Baby Brezza is a device that can prepare your baby’s formula quickly and easily. It is completely safe and is used in this study to make formula preparation easier for the mother.

Are there any risks involved in this study?

If my newborn has been breastfed previously, can I still participate?

Yes. You need to just not have breastfed your infant within the 7 days leading up to consenting to participate, and exclusively bottle feed during the duration of the study.

Is there compensation for my participation?

Yes! There is compensation available for your time and participation of up to $XXX and a 30-day supply of the commercially available study probiotic at the end of the study along with the Baby Brezza.

How does the study work?
