Figure 1

Phyla composition of the gut microbiota in overweight volunteers after 180 days of supplementation. Shown are the abundance of the phyla profile (A); heatmap of the microbial phyla abundance with statistical significance (B); and Firmicutes/Bacteroidetes ratio (F/B ratio) (C); from time zero [T(0)] and 180 days [T(180)] post-supplementation with NSupple (n = 21) and NSupple_Silybum (n = 20) in overweight volunteers. Values are expressed as the percent of relative abundance (mean ± standard deviation). *p < 0.05, **p < 0.01, ***p < 0.001, ***p < 0.001.
