LACTOBACILLUS HELVETICUS LAFTI® L10 : A MICROBIOTA STRAIN WITH PROVEN EFFICACY ON INTESTINAL COMFORT AND AGAINST CANDIDIASIS

 

Lactobacillus helveticus, an isolated Gram+ rod-shaped bacterium, is a lactic acid bacterium widely used in the manufacture of fermented dairy products. It is notably present in Swiss Emmental cheese, hence its Latin name « helveticus ». In addition to their use in the manufacture of certain cheeses, some strains of L. helveticus also have beneficial properties for intestinal health1 and in cases of candidiasis2.

 

The registered strain of L. helveticus LAFTI® L10 is resistant to gastric acidity and bile3, and is characterised by strong adhesion to the intestinal epithelium4, making it the strain of choice for improving intestinal comfort and combating candidiasis.

 

In vivo gastrointestinal models have shown the ability of L. helveticus LAFTI® L10  to:

  • Support natural defences by competing with pathogens such as Listeria monocytogenes, E. coli and Candida albicans 5
  • Act in synergy with prebiotic fibres: FOS and inulin 6
  • Modulate the pro-inflammatory response: decrease in colonic myeloperoxidase (MPO) activity, decrease in the production of the inflammatory mediator LTB4, increase in glutathione levels and support antioxidant metabolism 3.

In a clinical study of 60 adults, L. helveticus LAFTI® L10 significantly reduced occasional gastrointestinal upset 7.

In addition, a mechanistic study showed that L. helveticus LAFTI® L10 prevented colonisation by C. albicans, the main pathogen responsible for vaginal bacteriosis2.
