The health-improving effect is provided by the properties of bacteria Bacillus subtilis & Bacillus amyloliquefaciens. Reproducing in the intestine they produce biological active substances which inhibit the growth and development of pathogenic and opportunistic microflora. Owing to this process the composition of the intestinal microbial communities becomes in compliance with the evolutionary normal rate. The intestine walls are cleaned from some indigestible constituents of food, thus this process promotes active removal of toxins from a body; biological active substances and nutrients can be delivered without hindrance.
