Nurosym is a medically certified, non-invasive vagus nerve stimulation device developed by Parasym. It uses transcutaneous auricular vagus nerve stimulation (taVNS) to send gentle electrical impulses through the ear to the brain, with the goal of restoring balance to the autonomic nervous system. This can help reduce symptoms related to stress, inflammation, and chronic health conditions.
How does Nurosym work?
Nurosym stimulates the vagus nerve through an ear clip that is placed on the left ear.
What is the function of the vagus nerve?
- Regulation of breathing and heart rate
- Regulates digestion
- Reduces stress and inflammation
- Affects the brain and mood
- Controls the throat and speech
What is nurosym?
- Reduces inflammatory markers and oxidative stress
- Improve heart rate variability (HRV)
- Increased Cognitive Function
- Stabilizes mood and sleep
- Supports digestion through improved communication in the gut-brain axis
The device is CE marked in the EU and has been assessed as “Non-Significant Risk” by the FDA in several US studies. It has been validated through over 50 clinical studies in collaboration with institutions such as Harvard and UCLA.
Who can benefit from Nurosym?
Nurosym is designed for people who experience symptoms related to dysregulation of the autonomic nervous system, such as:
- Prolonged fatigue and brain fog
- Sleep disorders
- Anxiety and depression
- Digestive problems (such as IBS)
- Post-viral symptoms (such as after COVID-19)
- Chronic pain and inflammatory conditions
Important considerations
Nurosym is not recommended for people who:
- Has undergone surgical removal of the vagus nerve.
- Have active implants such as a pacemaker or cochlear implant.
Consult a healthcare professional before use.
