Is a unique probiotic designed to deliver active organisms that have been shown to promote healthy gut flora, protect intestinal integrity and boost immune function. Each scoop provides seven probiotic strains selected for their ability to withstand the harsh gastrointestinal (GI) environment and adhere to the intestinal tract. The blend includes Saccharomyces boulardii, a microorganism shown to help restore microflora balance by enhancing “resident” probiotics. It also increases levels of the crucial antibody, secretory IgA, and thus creates a first line of defense to help bind and clear harmful bacteria. The GI tract is a finely balanced environment where 300 different strains of bacteria compete for space and nutrients. Because probiotics are live organisms, there are challenges associated with manufacturing and distributing probiotic supplements. Ortho Biotic features Bioshield technology, an innovative process that effectively preserves probiotic organisms.
