Bifidobacterium Infantis NLS Super Strain

ACTIVE COMPARATOR

Participants in the probiotic period will take two capsules of Bifidobacterium infantis NLS super strain (Natren LIFE START®2) three times per day for three weeks. Each capsule contains 2 x 10\^9 colony-forming units (CFU) of Bifidobacterium infantis NLS super strain, for a total daily dose of 12 X 10\^9 CFU. The probiotic will be kept refrigerated during transportation and throughout the study period.

Dietary Supplement: Bifidobacterium infantis NLS super strain (Natren LIFE START®2)

Placebo

PLACEBO COMPARATOR

Participants in the placebo period will take two capsules of placebo three times per day for three weeks. The placebo capsules contain rice flour, hydroxypropyl and methylcellulose. The placebo will be kept refrigerated during transportation and throughout the study period.

Other: Placebo
