The Parasym AVNT technology is a general wellness product which means it can affect your nervous system. It emits specifically designed electrical impulses to the brain, through this clip, which attaches to tragus of your ear which affects the auricular branch of the vagus nerve.
Ashley Ridout
Osteopath
I've found two big benefits for Parasym AVNT technology wellness product. I found that it certainly helps me focus, there are studies definitely to support that and I've found that it improved my HRV when I've measured it.

There is this wellness product that you just clip on your ear one hour each day and it improves your concentration, your sleep, your overall mood and it reduces your anxious states and low mood and many more things.
Marco Sander
Psychologist
I've been using Parasym AVNT technology with my users and at home. I found the concept of vagus nerve stimulation online, and it seems helpful for users with widespread body pain, chronic tiredness, or post-viral fatigue symptoms.
John Evans
Osteopath
I'm a cranial sacral therapist from Vancouver, Canada. After seeing great progress in a client using Parasym AVNT technology, I tried it for myself. It helped regulate my sensitive nervous system, and after an initial adjustment period, I noticed significant improvements

Your body’s ability to fight off illness and sustain energy depends on a well-regulated nervous system. Past infections or chronic stress can dysregulate your system leaving you fatigued, mentally foggy, and more vulnerable to illness.
Counter Burnout & Persistent Fatigue
Fatigue is the body's response to prolonged stress and systemic inflammation. Nurosym restores autonomic balance, reducing inflammatory fatigue and supporting sustained energy production.
Patented Target
A dysregulated nervous system weakens immune defenses and makes us susceptible to illness, post-viral symptoms, and slows recovery from infections. Stimulating the vagus nerve unlocks parasympathetic activity and regulates immune function.
Neural Communication
Infections come with disruption in cognitive function and inability to focus caused by poor blood flow and brain inflammation. Support clearer thinking by improving brain oxygenation and accelerating neural recovery.
Inflammation is the silent enemy to performance—it slows recovery from sports injuries, disrupts sleep, and accelerates cognitive decline. Poor sleep and chronic inflammation strain your heart, delay muscle repair, and weaken mental sharpness over time.
Nurosym is scientifically proven to:
helping you recover faster, sleep deeper, and think sharper—so you can sustain peak performance every day.

Reduction in anxious states
In a clinical trial, targeted stimulation of the vagus nerve increased vagal tone and inhibited cytokine production in the inflammatory process. Both are important mechanisms for anxiety resilience.
Reduced fatigue & increased energy
In the study, patients reported sustained improvements even one week after discontinuing the therapy, indicating prolonged relief from fatigue-related symptoms.
Improvement in HRV & Vagus Nerve activity
In a clinical trial, a one-hour session of Nurosym favourably altered all parameters of Heart Rate Variability, when compared to a placebo. HRV indicates activation of psychophysiological self-repair mechanisms.
