The role of probiotics in the gut
The human body is colonised by trillions of microbes which include bacteria, viruses and fungi. The term microbiome includes the genetic material of all the microbes that live on and inside the human body. It is estimated that the human microbiome may weigh approximately two kilograms. The majority of the microbes live in the gut, primarily in the large intestine and are referred to as the gut microbiome. The bacteria in the gut microbiome aid digestion, regulate the immune system, protect against other bacteria that cause disease (pathogenic bacteria) and may be involved in producing vitamins.
