Arms and Interventions
Participant Group / ArmParticipant Group / Arm |
Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Active Comparator: Probiotic (BEO001)
Participants receive the BEO001 probiotic powder, which contains two probiotic strains
|
A mixture of two probiotic strains.
Total dose ≥5x10^10 CFU of each strain per intervention day.
Administered as a powder mixed with water, consumed in several portions.
|
|
Active Comparator: Synbiotic (BEO001 + Beta-Glucan)
Participants receive the BEO001 probiotic powder plus beta-glucan fiber powder.
|
The BEO001 probiotic (as above) co-administered with 3g of a food-grade beta-glucan fiber.
Both are powders mixed with water.
|
|
Placebo Comparator: Placebo
Participants receive placebo powder.
|
Powder without the active probiotic strains or beta-glucan
