Your health and happiness depend on a network of 200,000 nerve fibers that hold the secrets to life itself.

Great Nerve is both a masterpiece and a timeless document for those who want to see what science means: faith, focus, patience, and hard work.

The vagus nerve is often referred to as the “highway” that connects every organ in the body to the brain and vice versa, but it is much more than a simple pathway. The “great nerve” resonates in harmony with your health like the instruments of an orchestra: when your vagus nerve is healthy, so are you. When it is not, you may experience everything from poor sleep to low mood, pain, distress, and chronic conditions.

Recent scientific advancements, including Dr. Kevin Tracy’s research showing how the vagus nerve is connected to the immune system, have brought the nerve to the attention of everyone from neuroscientists to TikTok influencers.

In Great Nerve, Dr. Tracy shares the science of how the vagus nerve regulates our health, how we can support it, and the truth behind popular “vagus nerve stimulation” strategies such as ice baths, meditation, exercise, and breathing.

He reveals the wondrous new science that promises to revolutionize healthcare, where computers may regulate blood glucose, and electrical implants may replace medications forever.

The groundbreaking vagus nerve stimulation therapy pioneered by Dr. Tracy shows potential to reverse life-altering diseases such as rheumatoid arthritis, inflammatory bowel disease, lupus, multiple sclerosis, diabetes, obesity, stroke, depression, and Alzheimer’s and Parkinson’s diseases.

Great Nerve not only revolutionizes how we understand and treat diseases but also gives us unprecedented hope for our health.
