The Xoçai™ XoBiotic Squares™ The Xoçai™ XoBiotic Squares™ will be in the form of an 11-gram square and will deliver 1 billion microorganisms of two types— Lactobacillus Helveticus R0052 and Bifido Bacterium Longum R0175. These probiotics have been selected for our probiotic chocolate because of their stability in chocolate and their guaranteed shelf life equal to the shelf life of the chocolate itself, if properly stored as recommended for all Xoçai™ products (40*F – 75*F). By marrying the health benefits of dark chocolate with those of these two probiotic cultures, which have a positive influence on immune and gut health, we gain new opportunities with health-conscious consumers. Presently there are no approved health claims on probiotics in the US, until now!
