Advanced Info Natural Factors Ultimate Multi Probiotic provides probiotic strains that support digestive health and immunity. Each strain has been specially selected and cultured for their compatibility and natural resistance to gastric acid, allowing the probiotics to reach the intestines at full potency. This formulation offers both Lactobacilli to support small intestine health, along with Bifidobacteria, the most prevalent friendly bacteria in the large intestine. Together, these strains of probiotics help maintain the permeability of the intestinal barrier, and support overall health and well-being. With age, illness, and antibiotic use, healthy gut bacteria begin to decline, increasing susceptibility to pathogenic colonization and resulting in inflammation, tissue damage, and immune system dysfunction. Each strain in the formula has natural resistance to gastric acids. Gastric resistance is critical to surviving the stomach’s acidity without an enteric coating and reaching the intestines at full potency.
