Lactobacillus brevis is a species of lactic acid bacteria found naturally in fermented foods and in the human gut and mouth. Supplement forms are cultured and freeze-dried, then measured in colony-forming units (CFU) rather than by weight.

Why it’s used

Taken by some as a probiotic with interest in digestive or oral health support, since specific strains of this species have been studied for such uses.

What the evidence says

NIH's Office of Dietary Supplements notes that probiotic effects are strain-specific, meaning results with one Lactobacillus brevis strain do not necessarily apply to another. Some small trials have looked at particular L. brevis strains for oral health markers or gut symptoms, but the overall body of human evidence is limited in size and consistency, and CFU counts rather than mass are used to describe dosing.

Context

Studies use colony-forming unit (CFU) counts rather than milligram or gram doses, and specific strains and CFU amounts vary considerably between trials, limiting generalization across products.
