When we refer to gut health as a whole we are talking about the entire digestive tract or gastrointestinal system. This system begins in the mouth, where food enters and includes the oesophagus, stomach, intestines and colon.

Today, we’ll see how probiotics fit into this environment, and we’ll also look at the health benefits and potential risks of supplementing with probiotics.
