What is the Gut Microbiome?

Your “gut microbiome” is made up of trillions of microorganisms and their genetic material that live in your intestinal tract. These microorganisms, consisting mainly of bacteria, are involved in functions critical to your health and wellbeing. These bacteria live in your digestive system and they play a key role in digesting the food you eat, helping with absorption and synthesis of nutrients, regulating your metabolism, body weight and immune system, as well as helping to support brain function.
