Advenza Bacillus clausii (AVZ 7911™): A Proven Probiotic Strain with Preclinical Toxicological Studies manufactured in a WHO cGMP certified facility.

Antibiotics wipe out infection and your good gut bacteria too. That’s why you need a probiotic like AVZ 7911™ — which helps protect one from infection and restore the gut balance.

In the competitive landscape of probiotics, Bacillus clausii is known for its proven benefits in supporting gut health, preventing antibiotic-associated diarrhoea, and boosting immunity. However, while Bacillus clausii is widely used, only select strains demonstrate the superior efficacy required for optimal clinical and commercial performance. Introducing, Bacillus clausii -AVZ 7911™, a distinct, clinically advanced proprietary strain developed by Advenza, which is redefining the standards for probiotic performance — especially during antibiotic treatment.

The biggest challenge for probiotics administered alongside antibiotics is simple: survival. Most probiotics are destroyed by the very antibiotics prescribed to treat infections. But AVZ 7911™ is different. It is a poly-antibiotic resistant strain, and endures the onslaught created by several of the most popular antibiotics.

AVZ 7911™ is uniquely resistant to a broad range of antibiotics, including:

  • Penicillin
  • Cephalosporins
  • Tetracycline
  • Macrolides
  • Aminoglycosides
  • Novobiocin
  • Chloramphenicol
  • Thiamphenicol
  • Lincomycin
  • Isoniazid
  • Cycloserine
  • Rifampicin
  • Nalidixic acid
  • Pipemidic acid

This poly-antibiotic resistance means AVZ 7911™ can be safely and effectively administered during antibiotic treatment — without being wiped out by the very medications it’s meant to support.
