A diverse community of microorganisms (including bacteria, viruses, and fungi) live within our gastrointestinal tract and make up what is collectively called the gut microbiome. They are responsible for vital immune, metabolic, and nutritional functions and work together to keep the body healthy and prevent disease. For example, some bacteria help produce vitamins, digest food or destroy diseasecausing cells. Everyone’s microbiome is unique. No two people have the same microbial cells, even twins are different. Many gastrointestinal disorders have been associated with alterations in the gut microbiome. The role of bacteria in the human body has been studied extensively and identified as a means to improve health and prevent disease by balancing the gut microbiome using living microbial adjuncts, known as probiotics.
