In addition to the device itself, I offer educational resources, implementation guidance, and coaching support to help individuals integrate vagus nerve stimulation thoughtfully within a broader nervous system regulation and recovery framework.
While many individuals do well with electrical vagus nerve stimulation, I have found ultrasound stimulation to be an especially gentle option for highly sensitive nervous systems. The ZenBud Series 2’s no-sensation design and ease of use make it one of my preferred options for individuals looking for a simple and approachable introduction to vagus nerve stimulation.
The updated ZenBud Series 2 device offers a gentle, non-invasive approach to vagus nerve stimulation using therapeutic ultrasound rather than electrical stimulation. Its no-sensation design and simplified usability make it especially accessible for individuals with sensitive nervous systems or those looking for a calmer introduction to nervous system regulation work.
One of the biggest improvements in the Series 2 device is its direct USB-C connectivity. Rather than requiring a separate battery pack, the device plugs directly into phones, tablets, and other compatible devices, allowing individuals to comfortably listen to music, podcasts, meditations, or other audio while using stimulation. This streamlined design makes daily implementation simpler and more convenient.
By using therapeutic ultrasound rather than electrical stimulation, the ZenBud Series 2 provides a gentle option for individuals with Long COVID, ME/CFS, POTS, chronic stress, gut issues, and other forms of autonomic nervous system dysregulation as part of a broader recovery and regulation approach.
Many individuals find that having education and guidance helps them implement vagus nerve stimulation more effectively and with greater confidence.
This video course provides a structured introduction to nervous system regulation, vagus nerve stimulation, state-dependent pacing, and recovery-oriented implementation strategies.
Inside the course, you’ll learn:
• How vagus nerve stimulation supports nervous system regulation
• The foundational principles behind The Conrad Protocol™
• State-dependent pacing and nervous system awareness
• How to use the Polyvagal Chart to better understand nervous system state
• Practical strategies for implementing vagus nerve stimulation thoughtfully and gradually

VNS activates the body’s parasympathetic (“rest and digest”) response, helping regulate:
Heart rate and blood pressure
Mood and stress resilience
Digestion and gut health
Immune and inflammatory response
Energy and sleep cycles
It’s a clinically supported and user-friendly tool for restoring balance to a dysregulated nervous system—especially helpful for conditions where the body is stuck in “fight, flight, or freeze.”
