The vagus nerve is the most important nerve you probably didn't know you had. It is a long meandering bundle of motor and sensory fibers that links the brain stem to the heart, lungs, and gut. It also branches out to touch and interact with the liver, spleen, gallbladder, ureter, female fertility organs, neck, ears, tongue, and kidneys. Dr Justin Hoffman, a Santa Rosa, California, licensed naturopathic medical physician, says: "Without the vagus nerve, key functions that keep us alive would not be maintained." Nationally recognized sports nutritionist, strength, and conditioning coach Brandon Mentore elaborates: "The vagus nerve is extremely critical to your overall health and is intimately tied in with multiple organs and systems of the body."
