Lactobacillus jensenii: Evidence and Clinical Applications

Introduction to Lactobacillus jensenii

The American Gastroenterological Association and other guideline societies recommend choosing evidence-based probiotic strains with established efficacy for the specific condition being treated, as effects cannot be extrapolated between different Lactobacillus species or even between strains of the same species 1, 2, 3

The World Health Organization and other health organizations suggest that for gastrointestinal disorders (IBD, IBS, antibiotic-associated diarrhea), Bifidobacterium and other Lactobacillus species (L. rhamnosus, L. reuteri) have substantially stronger evidence 4, 5, 6, 3
The European Food Safety Authority states that Bifidobacterium strains demonstrate superior ability to colonize the gut, shift microbiome composition, and confer broad health benefits compared to Lactobacillaceae species 5, 6

The National Institutes of Health guidelines indicate that established Lactobacillus probiotics typically use doses ranging from 10^8 to 10^10 CFU daily, and strain-specific dosing is critical—effects cannot be extrapolated between different Lactobacillus species or even between strains of the same species 7, 8, 4, 3

The American College of Gastroenterology recommends that for general gut health, consider Bifidobacterium lactis or Lactobacillus rhamnosus GG, which have robust clinical evidence 3
The Infectious Diseases Society of America suggests that for IBD, specific multi-strain formulations show promise in ulcerative colitis (though not Crohn's disease) 1, 2
The American Academy of Family Physicians states that for immune support/respiratory infections, probiotics with documented efficacy reduce upper respiratory tract infection episodes and duration 3
The European Society of Clinical Microbiology and Infectious Diseases notes that the probiotic market is relatively unregulated, with claims often transferred inappropriately between products with different formulations, and probiotic effects are highly strain-specific—no single strain possesses all beneficial effects attributed to probiotics generally 3, 1, 3
