The first wearable non-invasive Vagus Nerve stimulation device designed to precisely and effectively target symptoms of nervous system dysregulation.
The auricular branch of the Vagus Nerve that Nurosym targets is the only peripheral branch that reaches the skin, allowing non-invasive electrical stimulation to influence central vagal pathways
Our bodies have a distinct system that naturally manages our response to stress to keep us healthy & adaptable. That system is regulated by a largely underappreciated nerve called - the Vagus Nerve.
The Vagus Nerve, also known as cranial nerve X, is a 24/7 two-way hotline between your brain and nearly every major organ: heart, lungs, gut, liver, etc.
Keeping this nerve active is key to keeping us healthy and adaptable.
Over 70% of chronic conditions—including heart disease, fatigue, autoimmune disorders, and depression—are linked to chronic stress and inflammation, ie Vagus Nerve imbalance (1).
Persistently exposing your body to stressors (even simple ones like deadlines) may leave you stuck in a survival loop, fight-or-flight dominance, and visible symptoms like:
Some evidence suggests vagus nerve impairment can stem from various causes, including:
• surgical procedures [25],
• neurological disorders [25],
• diabetes [26],
• chronic stress [25],
• autoimmune conditions [26],
• exposure to toxins and alcohol [27],
• trauma [25],
• post-infection complications [26],
• heavy metals [27].
FUNCTIONAL OR STRUCTURAL
Some evidence suggests vagus nerve impairment can stem from various causes, including:
• Anxious thoughts, Panic, Trauma [2,3]
• Brain Fog [4]
• Chronic Tiredness [5]
• Cognitive Impairments [6]
• Problems swallowing [7]
• Persistent low mood [8]
• Seizures [9]
• Sleep problems [10]
• Dizziness and Headaches [1]
• Cardiovascular Symptoms: Abnormal Heart Rate [12], Fainting [1], Blood Pressure Problems [13]
• Gastrointestinal Issues: Digestive Issues [14,15], Reflux [16], Gastric paralysis[17], Vomiting and Nausea [18]
• Metabolic and Endocrine Disorders: Obesity [19], Blood sugar regulatigh problems [20, 21]
• Autoimmune and Inflammatory Conditions: Autoimmune Diseases [22], Chronic Inflammation [20, 23]
Researchers begin linking vagus nerve activity to heart rate, digestion, and autonomic control.
Electrical Vagus Nerve Stimulation (VNS) concept introduced by Dr. Jacob Zabara to treat epilepsy.
FDA approves implanted VNS for epilepsy and later depression — required $30k+ surgery and carried risks.
Parasym starts a decade-long effort to create a safe, non-invasive wearable VNS—no surgery needed.
Auricular (ear-based) Vagal Neuromodulation Therapy(TM) invented by Parasym to avoid side effects of neck-based VNS like muscle spasms or cardiac issues.
$10M+ in R&D, 50+ studies with Harvard, UCLA & more. Nurosym becomes the most studied wearable VNS, measurably activating Vagus Nerve by 61% within 5 min in placebo-controlled trials.
Nurosym helps your body maintain homeostasis, balancing your “rest and digest” response, countering "fight or flight" domination.
Responsible for "Rest and Digest" state
Responsible for "Fight or Flight" state
When it comes to anxiety the papers I've looked at do provide evidence of support that transcutaneous vagal nerve stimulation is effective at improving parasympathetic drive, it can reduce fatigue and personally I've seen this improves my HRV when using this device.

Step 1
The tragus is the front door to your Vagus Nerve.
It allows Nurosym to gently tap in and engage your autonomic nervous system with laser precision.
Step 2
Important: Adjust the power with every session so it remains a pleasant feeling and not causing you discomfort. Higher level or longer sessions doesn't mean better. Every session is unique depending on the state of your nervous system.
Start with lower levels and shorter sessions, assess, then gradually increase, but always make sure the feeling is pleasant and not causing you discomfort.
Shut down stress circuits
Start anti-inflammatory pathways
Trigger a cascade of therapeutic effects
Improve cognitive & physical performance
Step 3
You may notice your system winding down, shoulders dropping, leading to a clearer mind within minutes
Activating Your Parasympathetic Tone - The signal travels to a control center in the brainstem, telling the body to shift from stress mode into rest, recovery, and healing.
Step 4
When you apply Nurosym consistently you train your body to naturally favor a parasympathetic rest and digest state and easily shift balance away from sympathetic fight or flight dominance.
Speed up recovery and reduce soreness

When used correctly, Nurosym may boost parasympathetic activity by over 61% in just five minutes and deliver 2-4x greater parasympathetic activation than breathwork or meditation.
Use Nurosym as soon as you wake up to kickstart your parasympathetic system. This session helps set a calm, balanced tone for the day ahead. Especially useful for those managing symptoms like brain fog and fatigue.
Before/after a stressful meeting, heavy meal, or a tough workout, use Nurosym to reduce stress, aid digestion, or accelerate recovery. Integrates seamlessly into breaks or quiet work sessions.
Use Nurosym during your evening routine — whether you’re relaxing, reading, or winding down. Prepares your nervous system for deep, restorative sleep by lowering stress hormones and promoting calm.

“I could lift my arm. Walk to the bathroom. Eat sitting up. It felt like my body finally got the memo: you’re safe... There’s no single cure. But there are ways to help your system shift out of chaos—and into something quieter, steadier. For me, that changed everything.”
Filippe
ACTIVE PROFESSIONAL
“I remember doing a session late in the day before seeing friends. For the first time in months, I felt stable. That was huge. I use it alongside meditation, either together or one after the other. It became part of my daily routine.”
