Scientists have found many types of neurotransmitters that release chemicals and hormones that affect how we think, feel and behave. In fact, large amounts of serotonin are found in the gut which contribute to a feeling of happiness and aid GI digestion. Your gut microbes also produce gamma-aminobutyric acid (GABA), which helps you sleep and feel calm.^†††

Furthermore, your microbiome supports microbial fermentation of dietary fibers in the lower intestine and manufactures butyrate, a short chain fatty acid. Butyrate provides fuel for cells in your gut lining, supports immune system functions of the colon wall and helps to protect the digestive tract.
