Probiotic Super Dose is a vegetarian, dairy- and gluten-free, four-strain probiotic totaling 100 billion CFU† per capsule. Each vegetarian capsule is sealed in nitrogen-purged aluminum blister packs to serve as protection from factors proven to compromise the stability of probiotics such as heat, moisture, and oxygen. Probiotic Super Dose 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, Health4Life employs DRcaps™ gastro-resistant capsules. These specially designed, innovative capsules help slow exposure of actives to stomach acid and ensure more targeted release.
