Why does the microbiome have such an influence on our general well-being? In accordance with Dr. Meredith Wicklund, a neurologist at Mayo Clinic, “The microbiome creates completely different metabolites and neurotransmitters like serotonin and GABA that ship alerts to the mind and have an effect on how the mind is functioning.
