The term "gut microbiome" refers to the complex community of bacteria and microorganisms residing in the digestive tract. This microbial ecosystem plays a crucial role in digestion, metabolism, and immune function, impacting overall health. The gut microbiome is involved in breaking down food, synthesizing essential nutrients, and protecting against harmful pathogens. Additionally, emerging research links the gut microbiome to mental health, indicating that it may influence mood and cognitive function through the gut-brain axis.
