Therefore, the optimal dosage of the Lcr Regenerans® tablet to be administered and which will be equivalent to the daily administration of the Lcr Regenerans® capsule will be determined during this trial. To do this, 3 different dosages of the Lcr Regenerans® tablet, corresponding to or encompassing the time during which the tablet provides continuous release and presence of the strain in the in vitro model, will be compared to that of the Lcr Regenerans® capsule. For this reason, the frequencies of administration for the Lcr Regenerans® tablet will be 3, 4 or 5 days.
