Over 80% of immune cells are produced in the gut. It is a secret and invisible army, rigorously trained by good bacteria. These bacteria actively participate in the establishment of natural defenses. They help immune cells to recognize and attack pathogenic germs.

Lactobacillus gasseri is one of the most effective bacteria for optimizing the work of immune cells. In particular, it helps increase the body’s resistance to infections.

The presence of Lactobacillus gasseri in good quantity in the intestine brings enormous benefits !

– it participates in the production of antimicrobial peptides which play a major role in defense against pathogens;

– helps to make antibodies (secretory IgA) to prevent the adhesion of foreign germs to the mucosa and strengthen the junctions that weld intestinal cells;

– secretes bacteriocins (gassericins A) with antibiotic properties to a very broad spectrum of activity;

– boosts the production of gamma interferon (IFNy) with powerful antiviral powers;

– activates “natural killer” cells (NK cells) which identify infected cells and attack them;

– and it compromises the attachment of viral particles to the lung cell !

Repopulate your intestine with good bacteria!

Several studies have shown that daily consumption, for at least 4 weeks, of Lactobacillus gasseri probiotic reduces the duration and severity of respiratory tract infections. However, fragile, inflamed intestines damaged by taking antibiotics are devoid of this bacteria. Good to know !
