Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the effects of probiotic consumption on inflammatory outcomes and measures of gut health. Participants will be given yogurt with probiotics for one period and yogurt without probiotics for another, with a break in between. These periods will occur in random order.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental

Participants will consume one yogurt smoothie daily for the duration of the intervention that contains 3.16 × 109 colony forming units (CFU) bifidobacterium animalis subsp. lactis BB-12. Participants will be asked to refrain from consumption of other yogurt or probiotic-containing foods.

Group Type EXPERIMENTAL

Yogurt smoothie with BB-12

Intervention Type DRUG

During the one month intervention period, the participants will consume one yogurt smoothie with BB-12 daily.

Control

Participants will consume one yogurt smoothie daily for the duration of the intervention that contains no BB-12. Participants will be asked to refrain from consumption of other yogurt or probiotic-containing foods.
