Mice were supplemented with the vehicle, EC-0.5X, EC-1X and EC-2X for 28 days. Data is expressed as mean ± SEM (n = 10). The up arrows (↑) and down arrows (↓) indicate dose-dependent increase or decrease by EC supplementation. Significant difference from control group according to one-way ANOVA is indicated * p < 0.05, ** p < 0.01, *** p < 0.001.
