“You cannot hack your vagus nerve while ignoring what is chemically disrupting it in the first place.”

— Dr. Carolyn Dean

In this episode of Live with Dr. Carolyn Dean, Dr. Dean breaks down one of the biggest wellness trends right now: the vagus nerve—and why most of what you’re seeing online is missing the bigger picture. She connects the rise in “vagus nerve hacks” to the growing use of GLP-1 drugs and explains how both sugar toxicity and modern health trends are disrupting the nervous system at a deeper level than people realize.

Listen as she explores how nutrient depletion, poor diet, and misleading health marketing are contributing to fatigue, anxiety, metabolic dysfunction, and confusion in the wellness space. She also shares insights from her Maui Reset study, discusses magnesium absorption myths, and answers live audience questions on gut health, sleep, and supplementation.
