Our probiotic strains are stabilized using a patented polymatrix system that provides 50 billion micro-organisms through expiration date when stored at room temperature. Each bio-enhanced acid-resistant strain has been scientifically designed to survive stomach acid secretions during digestion, eliminating the need for enteric coating. This formula features the most dominant species of micro-organisms (Lactobacilli) that nourish and support the vaginal and urinary organs. Contains no salt, dairy, yeast, wheat, gluten, corn, soy, preservatives, artificial colors or flavors.
