What if the key to resolving your client’s chronic inflammation, metabolic dysfunction, or hormone imbalance was a neural switch hidden in the body? In this episode of ReInvent Healthcare, Dr. Ritamarie sits down with “The Vagus Nerve Doc,” Dr. Navaz Habib, to expose how vagus nerve activation regulates the immune system, improves digestion, and acts as the true foundation for healing. If your clients aren't getting results, even with the perfect diet or plan, this could be why.

Why the vagus nerve is more than just a “relaxation nerve” and what it controls

What the 80/15/5 rule reveals about the direction of vagus nerve communication
How to assess vagus tone with the BOLT score, no labs needed
