bstractObjective: To evaluate oro-cecal intestinal transit time (ITT) before and after administration of a dairy product containing Bifidobacterium BB12, Lactobacillus casei CRL 431 and fiber in healthy women.Methods: A prospective, randomised, double-blind and cross-over study with a 4-phase design (run-in: time 0 [T0], two intervention periods: time 1 [T1] and time 3[T3] and a wash-out: time 2, [T2]) was performed. Participants were asked about bowel movement and fiber consumption. ITT was assessed by the carmine red dye method.Results: Mean age was 40.7 years (n = 102 healthy women; 83 completed the study). In women with initial ITT (IITT) ≥ 48 h consuming the synbiotic product, meanIITT and final ITT (FITT) was 86.9 ± 38.5 h and 51.2 ± 29.8 h (-40.9%), as compared to women consuming the control yoghurt (IITT, 80.8 ± 31.7 h; FITT, 69.5 ± 31.5 h;-13.8%) (p = 0.001). IITT in women with functional constipation consuming the control yoghurt was 57.0
