A Parallel-group, Randomized, Placebo-controlled Ascending Dose Phase I Study Protocol for Dietary Supplementation With Bifidobacterium Longum Subsp. Infantis (B. Infantis) in Healthy Breastfed Infants


The purpose of this study is to investigate the dose of a probiotic supplement (Bifidobacterium longum subsp. infantis) required to achieve predominant gut colonization in healthy newborn, breastfed infants. The study will also examine whether supplementation with this probiotic can reduce the chance of developing eczema and food allergies in enrolled infants.
