How to Choose a Vagus Nerve Stimulator
Your vagus nerve is the longest nerve in your body, connecting your brain to your heart, lungs, and gut. It regulates the balance between your sympathetic ("fight or flight") and parasympathetic ("rest and digest") nervous systems. When vagal tone is strong, these systems work in balance. When it declines — from stress, ageing, illness, or inactivity — sleep suffers, stress accumulates, digestion slows, and recovery takes longer.
Transcutaneous vagus nerve stimulation (tVNS) activates the vagus nerve non-invasively through a branch that surfaces in the ear. Over 200 published papers have explored its effects on autonomic function, and the technique has been studied in clinical settings for more than two decades.
Not all vagus nerve stimulators work the same way. The most important distinction is how the device controls its output. Current-controlled devices (tVNS) measure your skin's impedance in real time and adjust the voltage to deliver a constant current to the nerve. Voltage-controlled devices (tENS) apply a fixed voltage, meaning the current fluctuates as skin conditions change. Since the therapeutic effect depends on the current reaching the nerve, current-controlled stimulation provides a more consistent and reproducible dose. This is why the majority of published clinical tVNS research uses current-controlled protocols.
Other factors worth considering include whether the device requires conductive gel (an ongoing cost and inconvenience), whether it needs a subscription or app to function, and whether it targets the ear or the neck. Auricular (ear-based) stimulation targets the tragus, which has the most direct vagal pathway to the brainstem and is supported by the widest body of published research.
Vagal offers three devices at different price points. Vagal Buddy ($349) and Vagal Oh! ($499) both use current-controlled stimulation via the EverSteady platform. Vagal Boost ($59) uses voltage-controlled stimulation and is an affordable entry point for people new to vagus nerve stimulation. All three stimulate through the ear, need no gel, have no subscription, and come with a 45-day money-back guarantee.

Questions and honest answers
Can I use tVNS if I have an arrhythmia or other heart condition?
Ask your cardiologist first. The vagus nerve directly influences heart rate and rhythm — that connection is part of how tVNS works — so if you have an arrhythmia such as atrial fibrillation, bradycardia, or tachycardia, or any other diagnosed heart condition, get individual advice from the doctor who knows your heart before using any vagus nerve stimulation device.
Do not use tVNS at all if you have a pacemaker, implanted defibrillator (ICD), or any other electronic medical implant. And if you ever notice palpitations or a change in your heart rhythm while using tVNS, stop and speak to your doctor.
If your cardiologist has questions, our support team is happy to provide clinical documentation and research references. Our devices are consumer wellness products and are not intended to diagnose, treat, cure, or prevent any disease, including heart rhythm disorders.
