Lactobacillus helveticus Rosell®-52Updated 2 days ago

What is Lactobacillus helveticus Rosell®‑52—and why is it in Biotic⁺?


Rosell®‑52 is a trademarked probiotic strain with a strong safety and efficacy profile. It’s taxonomically verified, QPS-approved by EFSA, and has been used safely since at 2006.


🤔 What benefits does Rosell®‑52 provide?


Clinical and lab research shows it:

  • Survives stomach acid and bile, with ~50% viability after 2 hours at low pH—so it reaches your gut alive 

  • Supports gut barrier integrity, protecting epithelial cell junctions and enhancing mucus production (Sherman et al., 2005)

  • Inhibits pathogens like E. coli, Campylobacter, Salmonella, and H. pylori in lab models (Johnson-Henry., et al 2005)


🤔 Why this specific (trademarked) strain?

  • Strain-verified & well-researched—Rosell®‑52 exists in cultures like CNCM/Pasteur and has a whole-genome sequence 

  • QPS-approved and globally recognised, appearing on EFSA, FDA, Health Canada, TGA and other regulatory lists 

  • Stable and practical—lactose-free and acid resistant


👤 How it works inside your body

  1. Survives digestion — stays viable through stomach acid and bile 

  2. Adheres to gut lining — supports mucus and tight junction integrity 

  3. Blocks harmful microbes — inhibits pathogens like E. coli and H. pylori in the gut 

  4. Supports digestive and immune health, with evidence from both pediatric and adult studies in combination formulations 


🤔 Why it’s included in Biotic⁺


Rosell®‑52 adds evidence-based support for gut barrier integrity, pathogen resistance, and digestive comfort. It’s a highly trusted, trademarked strain with decades of safe, robust use—perfectly matched to our mission of delivering consistent, science-backed benefits.
