ABSTRACT
Introduction: Yakult contains Lactobacillus casei strain Shirota (LcS). It has several protective effects on our digestive system which include preventing diarrhoea and improving constipation. The objective of our study was to determine the effect of a single dose of Yakult on whole gut transit time (WGTT) among young adults.
Methods: A cross-sectional study of 73 students who did not have any gastrointestinal disorder was performed. Subjects were given 4 carbon pills as a visual indicator to measure their WGTT in the normal setting of their usual activities. They then repeated measurement while consuming one dose of commercially available Yakult and 4 carbon pills (visual indicator). In the 2 settings, subjects were instructed to consume carbon pills and carbon pills with Yakult within 1 hour after bowel motion.
Results: The WGTT decreased in 48 of the 73 subjects (65.8%) after consuming Yakult. The mean WGTT was reduced by 4.4±14.6 hours. There was no significant effect of Yakult on the form of stools.
Conclusion: Yakult which contains Lactobacillus casei strain Shirota (LcS) is well known for helping in digestion and preventing constipation. A single dose of Yakult produces a reduction in the WGTT.
