I15: What does Nurosym do

With Nurosym you can:

  • Recover and activate your self-repair mechanisms by countering dysregulation in the nervous system.
  • Build up your stress resilience, recover faster from stressful events and help prevent mood swings.
  • Counter post-viral symptoms, like fatigue or brain fog.
  • Maintain optimal HRV, recovery and reduce cardiovascular health risks.
  • Relax and stabilise your mental state to help you fall asleep faster, achieve high-quality sleep, wake up more with more energy and fewer negative thoughts.
  • Improve digestive function by promoting healthy communication through the gut-brain axis.
  • Reduce inflammation, pain and discomfort linked to your nervous system.
  • Strengthen cognitive performance & focus to counteract the effects of aging.

How does Nurosym achieve all of this? 

Nurosym is a wearable device that sends electrical impulses to the brain via the vagus nerve to alleviate symptoms of dysregulated nervous system. Modern science has discovered that many chronic mental & physical symptoms are linked to chronically dysregulated nervous system. The nervous system and one of its largest nerves - the vagus nerve - controls all body functions, from breathing, heart rate, digestion to energy, calmness and mood. When the vagus nerve is not functioning properly, organs & systems of the body don’t work in harmony leading to poor physical & mental health. By strengthening the nervous system in a natural way through modulating the activity of the vagus nerve, Nurosym helps restore balance to the mind and body. 

Nurosym exerts its effects through various mechanisms:

  • It triggers the “rest and digest” response, promoting relaxation, lowering heart rate and improving digestion.
  • Reduces inflammation markers leading linked to pain & overactive immune response
  • Decreases oxidative stress markers linked to chronic diseases and ageing.
  • Increases neuroplasticity, rewiring the brain for better mood, better motor & cognitive learning and recovery from neurological symptoms.

This way Nurosym supports mental & physical health and helps alleviate symptoms of a range of symptoms.


Nurosym is a certified wearable device delivering proprietary Auricular Vagal Neuromodulation Therapy (AVNT)™ developed by Parasym, scientifically validated and optimised in 40+ scientific studies conducted in partnership with leading scientific research institutions including Harvard and UCLA.


Nurosym is the only certified wearable device approved for the purpose of targeting the vagus nerve via the ear available without prescription. It is the most studied neuromodulation system of this kind, widely considered as the gold standard in scientific neuromodulation research.
