Digestive Aids help maintain a healthy flow through the digestive tract. They help keep destructive bacteria and other pathogens from damaging the intestinal wall and getting through the cells lining the intestines and into the body (leaky gut syndrome).  If these bad bugs get through the wall of teh gut they get absorbed into the body and can cause disease and dysfunction.  Some digestive probiotics also help prevent the bacteria that causes tooth decay and gum disease.
