70-90% of your immune system surrounds your gut, as this is the main portal by which most things such as bacteria, viruses, molds and toxins gain entry into your body. Vive Biotics is designed to pass through the acidic environment of the stomach (most probiotics are destroyed here) and go into your gut where it seeks out and destroys mold toxins and bad bacteria while repopulating the healthy bacteria your body needs in order to function at its best.
