This study was to investigate the effects of the intake of Lactobacillus rhamnosus GG (LGG) on the defecation and skin condition of healthy adults by a randomized, double-blind, placebo-controlled study. Total 96 healthy adult volunteers with a tendency of constipation and dry skin were given lyophilized cells of LGG (1.4x10^10cfu/g) or placebo for 4 weeks. The defecation frequency at week 4 significantly increased after intake in both LGG group and placebo group (p<0.01). Fecal quantity at week 4 tended to increase after intake in the LGG group (p<0.1). The stratum corneum hydration of the inner forearm was higher in the LGG group than in the placebo group (p<0.01). After week 4 in the LGG group, the transepidermal water loss from the cheek was lower than before intake. A questionnaire on the skin state indicated that skin condition of the LGG group became better than that of placebo group. These results indicate that oral administration of LGG could positively influence the moisture content of skin by increasing the stratum corneum hydration and by inhibiting transepidermal water loss.
