LifeinU™ BSCU1 and Immunity, an efficiency supported by a clinical study

Share this article:

LifeinU™ BSCU1 is a unique stable probiotic which may support immune health. This probiotic, offered by Gnosis by Lesaffre, is a specific strain of Bacillus subtilis, a safe and common bacterium registered in the CNCM collection under the number I-2745 and protected by a patent.


The efficiency of LifeinU™ BSCU1 is supported by a clinical study, with the collaboration of Professor Philippe Marteau, head of gastroenterology of Saint Antoine hospital in Paris and expert in immunology.


This clinical study was conducted during the winter season, with a dosage of 2×109 CFU per day, to investigate LifeinU™ BSCU1 benefits on immunity. 


One of the markers monitored is the level of secretory immunoglobulins A (sIgA). sIgA are immune system antibodies secreted by the mucosal surfaces. They constitute the first line of defense against toxins and infectious agents. A deficiency in sIgA can weaken natural defenses increasing the risk of infection.


LifeinU™ BSCU1 may create a double protective effect by significantly increasing sIgA levels in the intestine and in the saliva, inducing the strengthening of natural defenses to fight infections.
