Our probiotic strains are stabilized using a patented polymatrix system that provides self stability when stored at room temperature, no refrigeration required. Each bio-enhanced acid-resistant strain has been scientifically designed to survive stomach acid secretions during digestion, eliminating the need for enteric coating, by preventing the destruction of viable cells that occurs when weaker strains are exposed to an acid environment. This children's acidophilus is a high-potency, multiple species probiotic supplement. It provides three of the best probiotic strains for children, in the amount that will support and nurture a healthy digestive system. Grape flavored. Contains no salt, dairy, wheat, gluten, corn, soy, preservatives, artificial colors or flavors.
