The CHILD (Canadian Wholesome Toddler Longitudinal Improvement) cohort examine adopted 1,157 mother-infant pairs over three years. The researchers assessed the connection between maternal and toddler vitamin D supplementation and the composition of the toddler’s intestine microbiome 5.
This examine discovered that supplementing the toddler’s weight loss program with vitamin D no matter feeding methodology was related to depleted ranges of the micro organism, Megamonas. Though there’s little analysis out there on this specific genus, Megamonas has been famous to be elevated within the microbiomes of male infants born to moms with prenatal asthma6.

Infants born to moms who complement their very own weight loss program with vitamin D prenatally and postnatally had been discovered to have a decrease abundance of the micro organism, Bilophila. Elevated degree of Bilophila have been present in infants with colic in contrast with controls8.
This isn’t the primary time that researchers have recognized an affiliation between vitamin D and microbiome composition, either9. In a scientific examine of wholesome adults, vitamin D consumption was additionally related to alterations to general intestine microbiome composition10. Nevertheless, though this hyperlink has been established throughout varied research, additional research are nonetheless required to establish which specific sorts (strains or genus) of micro organism are affected and what the consequences of those micro organism are on the person.
How does vitamin D affect our intestine microbiome?
?
Warning: that is about to get science-y! Particular receptors referred to as VDRs (Vitamin D Receptors) are current on the cells lining the intestine wall. When vitamin D binds to those receptors, it stimulates the manufacturing of the physique’s personal pure antimicrobial proteins, which goal and inhibit the expansion of dangerous micro organism within the gut11.
