THE SCIENCE

The Vagus Nerve:Your Body's Built-In Reset Button.

The vagus nerve runs from your brainstem through your heart, lungs, and gut, helping regulate stress and recovery. Most people never learn to work with it.

ZenBud targets your auricular branch, using focused ultrasound to help vagal tone over time.
