Outcome Measures

Primary Outcomes (1)

  • Comparison between groups of scores of Digestive Symptoms Frequency Questionnaire (DSFQ) during 28 days of investigational product consumption (the higher the score, the more severe are the symptoms, min:0, no symptom, max:16).

    From Baseline to Visit 4 (28 days).

Secondary Outcomes (4)

  • Comparison between groups of scores of Digestive Symptoms Frequency Questionnaire (DSFQ) during 28 days of investigational product consumption (the higher the score, the more severe are the symptoms, min:0, no symptom, max:16).

    From Baseline to each weekly evaluation visits (Week1 to Week 4) (4 weeks from baseline).

  • Comparison between groups of scores of Intestinal Gas Questionnaire (IGQ) during 28 days of investigational product consumption (the higher the score, the more severe are the symptoms, min:0).

    From Week0 (V2) to each weekly evaluation visits (Week1 to Week4).

  • Comparison between groups of scores of Profile of Mood States questionnaire Short Form (POMS-SF) during 28 days of investigational product consumption (a scoring guide needs to be follow to interpreted).

    From Week0 (V2) to Week2 (V3) and Week4 (V4).

  • Comparison between and within groups of total and living bacteria cells counts of B.lactis (method PMA-PCR) during 28 days of investigational product consumption and after 1 week following product consumption cessation.

    Between Week0 (V2), Week2 (V3), Week4 (V4) and Week5 (V5).

Other Outcomes (12)

  • Comparison between and within groups of Food Frequency Questionnaire (FFQ) during 28 days of investigational product consumption (an algorithm will be used to assess quantity and quality of nutriment intake, developed by MS Nutrition company).

    Between Week0 (V2) and Week4 (V4).

  • Comparison between groups of scores of Digestive Symptoms Frequency Questionnaire (DSFQ) during 28 days of investigational product consumption (the higher the score, the more severe are the symptoms, min:0, no symptom, max:16).

    From Week0 (V2) to each weekly evaluation visits (Week1 to Week4).

  • Comparison between groups of scores of Intestinal Gas Questionnaire (IGQ) during 28 days of investigational product consumption (the higher the score, the more severe are the symptoms, min:0).

    From Week0 (V2) to each weekly evaluation visits (Week1 to Week4).

Masking Details
The study Test and Control products have similar appearance including packaging and texture, smell, and taste, in order to preserve the double-blind methodology. The blinding of study products will be performed by assigning a study product number corresponding to the randomization list. Then blinded study product packages will be carried to the investigational site for assignment to the subjects. Product allocation will be performed by randomized method (IWRS validated system) as it is a Randomized Controlled Trial. The participants are thus assigned to intervention groups randomly.
