Lactobacillus acidophilus LA-1
Lactobacillus acidophilus LA-1 is a well-known probiotic strain with a research history dating to the 1990s, studied primarily through in vitro and animal model experiments. Laboratory work has documented bacteriocin production and adhesion to intestinal epithelial cells, including studies of attachment competition with enterovirulent bacteria. Animal model studies have examined immune and inflammatory modulation, including in the context of arthritis and colon health. Strain-specific human clinical trial evidence for LA-1 is limited. These are research topics, not findings; the papers do not establish that this strain treats or prevents any condition.
