100% Bifidobacterium strains This high-potency blend includes four extensively researched Bifidobacterium strains that reside primarily in the mucosal lining near the terminus of the small intestine, as well as in the colon and the genitourinary tract. These strains assist in creating a balanced intestinal environment by crowding out pathogenic bacteria and producing acetic and lactic acids that help inhibit the growth of unfriendly flora. Studies show that toxin-producing Clostridium species can accumulate in the bowel when levels of Bifidobacteria have decreased. Formulated with 10+ billion CFUs per capsule, Factor 4 utilizes InTactic technology and is an excellent choice for infants, children, and the elderly, or when tests reveal low levels of Bifidobacteria.
