Use of vitamin D drops alters infant fecal metabolites

Updated: May 23, 2023

A study published in Biomolecules has revealed that use of vitamin D supplements in infancy may differentially and independently influence infant gut microbiota metabolites. Using data on 575 infants from the CHILD Study, the study looked at whether use of infant vitamin D drops changes concentrations of certain metabolites, specifically glycerol and 1,2 propanediol (1,2-PD) concentrations, in the stools of infants at 3 months of age and characterized associations between these two molecules, and gut microbiota and their metabolites.



The study revealed that infants given vitamin D supplements were more likely to have high 1,2-PD and less likely to have high fecal glycerol compared to those not given vitamin D. Fecal 1,2-PD and glycerol concentrations were found to be negatively correlated with each other. Positive correlations between fecal 1,2-PD, Bifidobacteriaceae, Lactobacillaceae, Enterobacteriaceae and acetate levels were also observed.
