Efficacy and Safety of Oral Administration of Postibiotic by FOS Fermentation From Lactobacillus Paracasei in the Treatment of Irritable Bowel Syndrome.

A Randomized, Cross-over, Placebo-Controlled, Double-Blind Clinical Trial on the Efficacy and Safety of Oral Administration of Postibiotic by FOS Fermentation From Lactobacillus Paracasei in the Treatment of Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is a highly prevalent functional pathology which currently has no real standardized and effective therapy, despite having a significant impact on quality of life and on social-health costs.

Post-biotics have demonstrated in various in vitro and in vivo studies the ability to modulate the microbiota, the intestinal barrier function, the immune response as well as having systemic effects, with prospects for good efficacy in treatment of IBS.

PostbiotiX Slowing is a food supplement based on Fermented FOS from Lactobacillus paracasei CNCM I-5220, mallow and chamomile.

The Fermented FOS from Lactobacillus paracasei CNCM I-5220 (postbiotic) is the result of a controlled fermentation. The fermentation process allows to eliminate all the individual variability that depends on the microbiota, the diet and the psycho-physical conditions of the single individual, offering a mixture of bacterial metabolites and fermented fiber (postbiotic), which has the functional activity. In addition, as FOS is already fermented it does not induce the formation of gas typical of fiber fermentation in IBS patients, thus providing all the beneficial effects of the fiber without its side effects.

The fermented FOS from Lactobacillus paracasei CNCM I-5220 (postbiotic) is easily absorbed by the gut.

Dosage and method of use: PostbiotiX Slowing 4 g sachets, administered at the dosage of one sachet a day. To pour the contents of the sachet in a glass, add 150 ml of water, mix until complete dissolution of the powder and taken immediately, preferably as soon as awakened, and away from meals.
