Official title

Different Iron Exposure on the Development of Gut Microbiota From Birth to Four Months

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will look at the amount of iron in infant formula and how that affects a child's gut development. The children of mothers who plan to formula feed their children will be randomized to receive either high iron or low iron formula from birth until 4 months of age. Infants will consume only the study provided formula during enrollment. Blood and stool samples will be collected at birth and end of study to measure the effects of the iron exposure. The overall object is to compare high iron versus low iron exposure in formula-fed infants during the first months of life. Aims include determining the types of bacteria that are present in the infants' fecal microbiome, determining the effect of high iron exposure on gut microbiome and sleep patterns, and comparing iron status and homeostasis between the low and high iron formula groups.
