Longitudinal abundance of families in the gut microbiota at baseline and after iron supplementation. A linear mixed effects analysis with Bonferroni adjustment was performed and the abundance of selected bacterial families at baseline (B) or 2 weeks after iron supplementation (2w) is shown. A line connects the data points for each mouse before and after supplementation. Paired data points are indicated with green circles and outliers with white circles. ID iron-deficient, FS ferrous sulfate, SI Sucrosomial® iron. *P < 0.05, ** P < 0.01, ***P < 0.001
