Since 1991 (Elo et al., Lett. Appl. Microbiol.) Differences of adhesion of the strain L. rhamnosus GG depending on its product’s origin

2010 (Grześkowiak et al., British J. Nutr.) Inhibitory capacities on the pathogens cellular adhesion of L. GG are significantly different depending on its origin

the manufacturing process influence the characteristics of the strain

impact on clinical trials

2012 (Sảnchez et al., Trends in Food Science & Technology) The development of a dietary probiotic should integrate the influence of the technical constraints.

Unlike other probiotic producers, when manufacturing our probiotic we use a unique process called 3Biotic formula. It allows to administrate in the final product not only the probiotic, but as well the prebiotic and its natural postbiotics, integrated in a synergetic compound. The 3Biotic formula is generating a unique efficacy by creating a “bacterial training” effect through the stimulation of specific genes of the probiotic strain. As a result, probiotics coming from 3Biotic formula have an increased efficacy and confirmed in a recently published study(1) outstanding ability to resist to gastric acid and bile, inhibit pathogens and adhere to intestinal wall for biofilm creation.

Increased resistance to gastric acid than native strain

Conclusion

Candiflor1: Clinical study with 409 women. The usage of Gynophilus during 3 weeks gave a 40% reduction rate of candidiasis recurrence on a 6 months observational period.

Dapoigny et al: intake of Lcr35 in IBS-D patients implicated a 36% reduction of Francis score, with a remanence of at least 15 days…

Mechanism of action of probiotics is an extremely complex subject. The more we know… the less we know.
