Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Bifidobacteria, a genus of probiotic bacteria commonly found in the gut, has been studied for its potential effects on mental health, including anxiety. The concept of the "gut-brain axis"—the bidirectional communication between the gastrointestinal tract and the central nervous system—has prompted research into how gut microbiota may influence mood and anxiety. Several small-scale clinical trials and animal studies have examined specific strains of Bifidobacteria (such as Bifidobacterium longum and Bifidobacterium breve) for their effects on anxiety symptoms. Some studies report modest reductions in self-reported anxiety scores among participants taking certain Bifidobacteria-containing probiotics, possibly through mechanisms involving modulation of inflammation, neurotransmitter production, or cortisol levels.

However, the evidence is far from definitive. Most human studies have small sample sizes, short durations, and often use multi-strain probiotic formulations rather than Bifidobacteria alone. Meta-analyses and systematic reviews suggest a possible but inconsistent benefit, and the effect size tends to be small. The quality of evidence is generally rated as low to moderate, with a need for larger, well-controlled studies using standardized anxiety measures. Overall, while there is some scientific basis for the use of Bifidobacteria in supporting anxiety-related symptoms, it is not yet robust enough to be considered a primary or standalone treatment.
