Bifidobacterium lactis V9 is a probiotic strain developed in China (Inner Mongolia) that has been studied for its survival characteristics and potential interactions with gut microbiota. Observational research has examined gut microbial composition and, in one small study, hormonal parameters in women with polycystic ovary syndrome (PCOS); these findings are preliminary and not conclusive. Animal studies have explored non-alcoholic fatty liver and colitis models, and a 2025 RCT examined its use as an adjunct in colorectal cancer patients. Most of this evidence is early-stage and strain-specific human efficacy data remain limited. These are research topics, not findings; the papers do not establish that this strain treats or prevents any condition.
