Probiotic CD™ is a proprietary blend of 12 billion^ bio-active microorganisms from 10 naturally-derived vegetarian cultures. Specially formulated with a patented technology called BIO-tract®, this exclusive gel matrix creates a protective layer around the tablet as it travels through the digestive tract. BIO-tract® shields active organisms from stomach gastric acids, directing them to release in the gastrointestinal tract where food nutrients are more readily absorbed. Without BIO-tract® stomach gastric acids may destroy sensitive bacteria before they reach the intestinal tract - reducing the number of active organisms, lowering product effectiveness and impacting nutrient absorption. In a once daily dose, Probiotic CD™’s controlled delivery system gradually releases organisms over an extended period of time throughout the entire gastrointestinal tract. As microorganisms are released steadily through the protective gel layer, they continue to attach to specific sites in the gut where they are most beneficial. Controlled delivery ensures that the organisms remain active at consistent levels, providing balanced microorganism absorption and true potency. This represents a unique difference when compared to enteric-coated or non enteric-coated probiotics, which either release all probiotic microorganisms at one time or offer no protection from a harsh stomach environment. Once daily Probiotic CD™ delivers the all day digestive, intestinal and immune system support you can count on to feel good, hour after hour.
