NCT06768229

Brief Summary

The aim of this study is to explore the potential of a mix of 4 freeze-dried bifidobacteria strains from Danone collection to survive in human gastro-intestinal (GI) tract of healthy volunteers after 14 days of consumption. To this aim, one study group of 20 healthy volunteers will consume freeze-dried strains- mix twice per day diluted in 1 glass of still water during 14 consecutive days.

Outcome Measures

Primary Outcomes (4)

  • Presence of alive bacteria of each of the provided specific strains of Bifidobacterium strains in feces after 14 days of study product consumption in healthy adults.

    After 14 days of study product consumption

  • Comparison of the quantity of total and alive bacteria of each of the provided specific strains of Bifidobacterium strains in feces before and after 14 days of study product consumption in healthy adults.

    After 14 days of study product consumption

  • Presence of alive bacteria of the provided specific strains of each of the Bifidobacterium strains in feces after 1 week of follow-up in healthy adults.

    After 1 week of follow-up

  • Comparison of the quantity of total and alive bacteria of each of the provided specific strains of Bifidobacterium strains in feces after 1 week of follow-up in healthy adults.

    After 1 week of follow-up

Secondary Outcomes (1)

  • Dietary intakes collected by dietary recall (using MyFood24 software) of the previous day of the faecal samples collection for V2, V3 and V4 of healthy adult subjects.

    After 1 week of follow-up
