Brief Summary
This study aims to assess the impact of a chronic dietary intervention (8 weeks) with probiotics, specifically Fermented Milk Product with Probiotic (FMPP), on the mood of individuals with Major Depressive Disorder (MDD) refractory to standard antidepressant therapy, and its association with changes in intestinal microbiota and markers of inflammation.

Outcome Measures
Primary Outcomes (1)
Changes in total score on the Montgomery-Åsberg Depression Rating
The primary outcome measure will be change in the Montgomery-Åsberg Depression Rating Scale (MADRS). The MADRS is a 10-item scale for the evaluation of depressive symptoms (Montgomery \& Åsberg, 1979).
Baseline assessments and every 2 weeks over 91 days
Secondary Outcomes (3)
Changes in Clinical Global Impression-Severity Scale (CGI)
Baseline assessments and every 2 weeks over 91 days
Change in total score on the Computerized Adaptive Testing for Depression (CAT-D)
Baseline assessments and every 2 weeks over 91 days
Analysis of Intestinal Microbiota pre and post intervention
Baseline and after 56 days of intervention.
Study Arms (2)
BioKefir (BKP)
EXPERIMENTALBioKefir™ (Lifeway Foods) is a lactose-free fermented milk drink containing 12 different species of bacteria within the lactobacillus, bifidobacterium, and streptococcus generas totaling approximately 20 CFU per 3.5 ounce serving. The product also contains 2 g of fiber, including pectin and inulin. These fibers, especially inulin, are prebiotics that may function along with the probiotic species to support gastrointestinal health. The product is available commercially. Participants will be asked to consume 3.5 ounces twice daily, preferably at morning and nighttime. The probiotic will be provided in individual 3.5 ounce unlabeled containers. These quantities will be started on the first day of the intervention phase of the study (day 0, visit 0) and remain unchanged until the end of the intervention phase on day 56 (visit +4). Administration will be discontinued then.
Non-fermented Milk (NFM)
PLACEBO COMPARATORThe NFM is dairy-based product ultra-filtered to remove lactose. In addition to being matched to lactose, the NFM contains similar energy, fat, and protein content as the probiotic. Participants will be asked to consume 3.5 ounces twice daily, preferably at morning and nighttime. The NFM control will be provided in 11.5 ounce unlabeled containers. These quantities will be started on the first day of the intervention phase of the study (day 0, visit 0) and remain unchanged until the end of the intervention phase on day 56 (visit +4). Administration will be discontinued then.
Interventions
BKP BioKefir (Lifeway Foods) is a lactose-free fermented milk product containing 12 different bacteria provided in a drink.
