Immunity is one of the most important health concerns for consumers today! 36% of Ameri0cans have already reported an increase in their use of dietary supplements since the beginning of the COVID situation (1).

What are the health benefits of LifeinU™ BSCU1?

LifeinUTM BSCU1, offered by Gnosis by Lesaffre, contains a specific strain of the bacterium Bacillus subtilis CNCM I-2745. This probiotic can strengthen immune defenses by increasing the immune system’s SIgA antibody levels in the intestine and saliva. It has even been shown to reduce the frequency of upper respiratory tract infections in healthy, free-living seniors by 45%!

Have the effects of LifeinU™ BSCU1 been supported through any human clinical trials?

The effects of LifeinU™ BSCU1 on common winter infections in seniors have been studied in a clinical trial conducted by Professor Philippe Marteau (Saint Antoine Hospital, Paris, France)(2). This randomized, double-blind, placebo-controlled trial demonstrated how this product can stimulate the immune system and has the potential to decrease the frequency of winter infections.
