Flourish Biotic DF Daily 30 Billion™ is a vegetarian, dairy- and gluten-free, four-strain probiotic totaling 30 billion CFU† per capsule. Each vegetarian capsule is sealed in nitrogen-purged aluminum blister packs to serve as protection from factors proven to compromise stability of probiotics such as heat, moisture, and oxygen. Flourish Biotic DF Daily 30 Billion™ provides four researched strains of beneficial bacteria, including the extensively studied HN019 strain of Bifidobacterium lactis. These live microorganisms have proven health benefits and well-established safety, and have been tested for epithelial cell adhesion and/or resistance to low pH. To further support resistance to low pH and the delivery of microorganisms to the small intestines, XYMOGEN employs DRcaps™ gastro-resistant capsules. These specially designed, innovative capsules help slow exposure of actives to stomach acid and ensure more targeted release.
