Billions of beneficial bacteria, commonly referred to as probiotics, live in the human body. These bacteria are part of what keeps the body in balance in order to maintain overall good health. They reside in the human digestive system, specifically the intestinal tract also referred to as the gut, (as well as in the mouth, on the skin, in the colon, etc), and are integral to gastrointestinal functions. Over recent years,scientists are starting to discover that these microorganisms also play a role in immunological, metabolic, and neurological diseases.
