1. Restoration of the natural gut microbiota balance

  • Microbiota friendly effect: reinforcement of the intestinal microbiota through inhibition of enterovirulent bacteria and support of the natural bacteria of the microbiota.

2. lmmuno-stimulation

Stimulates natural defenses:

  • Enhancement of non-specific immune-stimulation of mucosal IgA production.

3. Inhibition of pathogens inducing diarrhoea (viruses and bacteria)

  • Antagonistic or regulatory activity towards viruses and bacteria: neutralization and inhibition of pathogen-activated cell signalling pathways.
  • Adhesion to the mucosa: inhibition of the attachment of pathogens and their internalisation.
  • Bacteriostatic effect: blockage of the growth of enterovirulent bacteria as a result of strain-specific production of antibacterial compounds.

Lactéol fort® is
Recommended by ESPGHAN* Pediatric Guidelines10 and Hong Kong College of Paediatricians Guideline
for treatment of diarrhoea.

Publications about Lactéol®

The active ingredient of Lactéol® is heat-treated Lactobacillus LB and its culture medium. Lactéol® is one of the most scientifically well documented micro-organism based therapeutics in the world regarding both efficacy and safety. In the past 30 years well over 50 articles describing Lactobacillus LB have been published in peer-reviewed scientific journals.

Acute diarrhoea

Acute diarrhoea in children

A Randomised controlled trials in children Addition of L. acidophilus LB to oral rehydration therapy was effective in the treatment of children aged 3 to 24 months with acute diarrhoea by decreasing the duration of diarrhoea.

Chronic Diarrhoea

Chronic diarrhoea

In a multicentre RCT, involved 137 patients with chronic diarroea, the clinical symptoms were markedly improved in the Lactéol fort ® group, indicating that L. acidophilus LB is more effective than living lactobacilli

[Lacidophilin®] in the 4-week treatment of chronic diarrhoea.

Antibiotic Associted Diarrhoea

Antibiotic-associated diarrhoea

An exploratory study (n=325) on the effect of Lactéol® on antibiotic – associated bowel disturbances in a primary care population suggest that a 1-week Lactéol ® treatment may reduce the risks of diarrhoea associated with antibiotic treatment.

Irritable Bowel Disease (IBS)

Irritable bowel syndrome

An observational investigation (n=297) demonstrated beneficial effect in health-related quality of life (including no. of symptomatic days, no. of stools and consistency of stools) with no side effects in patients with IBS-D.

Bifidogenic Effect

Bifidogenic Effect

A newly published pre-clinical trial demonstrated Lactobacillus LB stimulated the growth of bifidobacteria in human fermented fecal communities and in pure culture.
