QTY - 30 Acid-Resistant Vegetarian Capsules

AB Companion is ideal for individuals seeking a well-rounded supplement to support a healthy balance of intestinal flora, cellular health, and immune health. It features four probiotic strains, including the extensively studied HN019 strain of Bifidobacterium lactis, plus Saccharomyces boulardii (Sb), a non-pathogenic yeast, to further complement healthy gastrointestinal ecology. Gastro-resistant, vegetarian capsules provide an innovative solution for targeted delivery of sensitive ingredients to the small intestine, as they alleviate exposure to the low pH environment of the stomach. Additionally, each capsule is sealed in a nitrogen-purged blister pack to provide protection from heat, moisture, and oxygen, factors known to compromise probiotic stability.*

  • Balanced wellness pack
  • Supports immune, gut,  and cellular health
  • Formulated with premier probiotic strains
  • Nitrogen-purged blister pack

Journey into wellness with a balanced selection of supplements that support your immune, gut, and cellular health. Take advantage of premium probiotics that implement the HN019 strain of bifidobacterium lactis, all in a nitrogen-purged blister pack to preserve the integrity of the supplements.

 The Science

Diversity of gut microflora is characteristic of a healthy GI microbiome and contributes to overall health and vitality by promoting optimum digestion, assimilation, gut integrity, motility, and efficient removal of toxins and wastes. Many internal and external influences, including stress, a poor diet, food sensitivities, medication, environmental factors, and certain disease conditions, can impact the microbial balance within this fine-tuned community. Their impact can allow potential colonization by pathogenic organisms and disrupt a healthy balance, which can result in adverse effects ranging from GI symptoms to impaired immune response.[1-3] Probiotics are part of the key to promoting the optimal balance of the microbiome,[4] whether they originate from dietary sources or from supplements. Probiotic yeasts, such as Saccharomyces boulardii, also play a role in gut ecology by supporting intestinal barrier function and integrity.*

Careful selection of organisms is another way Bock Nutritionals helps ensure stability and digestive survivability. To further support resistance to low pH and the delivery of microorganisms to the small intestines, Bock Nutritionals encapsulates the ingredients in gastro-resistant DRcaps™. These specially designed, innovative capsules help slow exposure of actives to stomach acid to promote a more targeted release.*
