                                Approximately 90% of the body’s serotonin, a crucial neurotransmitter for mood regulation, is produced in the gut and is influenced by the state of your gut microbiome. While you cannot directly feed your brain microbiome, you can significantly influence brain health and function by nourishing the trillions of microbes that reside in your gut.
