Changes in the fecal color score in the randomized placebo-controlled crossover clinical study. Fecal color was recorded daily by the subjects, who compared the color with the tones of five color stages on a card. The scores for the tones of the five stages were from 1, light yellow, to 5, dark brown, in incremental steps. Average changes in the fecal color score during the LF+LB or placebo tablet ingestion period are shown. *p<0.05 in the Student’s t-test for the fecal color score before and after the tablet ingestion period. ^†p=0.1 in the Student’s t-test between the average difference during the LF+LB tablet ingestion period and that during the placebo tablet ingestion period.
