ProbioMax Daily DF 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. ProbioMax Daily DF 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.
