About Nurosym
Written by the company
Nurosym is the most studied CE-marked non-invasive vagal neuromodulation system in the world.
The Nurosym device sends patented electrical signals to the brain via the vagus nerve, activating specific therapeutic mechanisms that can counter dysregulation in the nervous system and significantly improve health outcomes, as proven by scientific studies.
Nurosym harnesses advanced neuromodulation technology in a sleek and easy-to-use wearable device. Validated by the world’s most elite research institutions in randomised placebo controlled scientific studies.
Why Trust Nurosym?
Written by the company
- Gold standard in scientific research
- Nurosym is a certified wearable device, with over $10M deployed in scientific research, 60+ partner research organisations including Harvard, UCLU, 50+ published papers in leading journals covering our exciting and scientifically significant results. This is why Nurosym is the leading non-invasive vagal neuromodulation system used in scientific neuromodulation research and now widely adopted.
- Certified wearable device with confirmed safety
- Exposing your nervous system and brain to untested electrical currents can put you at risk of a permanent damage to the brainstem and vagal nerve fibres, worsening your symptoms. Never use or suggest using DIY electrical current devices on your nervous system. Ensuring safety and efficacy requires extensive scientific studies that cost millions of dollars. This is why few Neuromodulation devices have been certified by health regulatory bodies as safe and effective. Beware of websites claiming to deliver benefits from uncertified therapies that present online reviews instead of scientific evidence. Carefully verify if a therapy you’re evaluating is registered as a wearable device, which certifies it is safe and effective to use. When considering any health intervention, be sure to evaluate the status of certification, scientific evidence, warnings and seek advice of trusted health care professionals. Nurosym is one of a few registered neuromodulation based wearable devices with safety confirmed by regulatory bodies in EU in Randomised Placebo Controlled Studies. Nurosym has a CE Mark in the EU and has been awarded FDA Non-Significant Risk Designation, which both confirm safety of our device.
- Proven target activity
- In addition to safety, it is crucial to consider efficacy of various devices. The fact that a device is delivering a safe electrical current is not enough. It also needs to demonstrate that it indeed stimulates the right nerves and activates them. Triggering nerve action potential to fire requires precise waveform, frequency, wavelength and amplitude of electrical signal, as well as a specific stimulation site on the body closest to a particular branch of the vagus nerve. Without scientific data, we cannot know if a device is 1)actually stimulating the right neural pathways 2)not stimulating unintended neural pathway. Nurosym is demonstrated in scientific studies to stimulate the brainstem via the vagus nerve. Our patented waveform that exerts these effects has been developed over 8 years of laborious research with a total cost of over $10M.
- Efficacy confirmed in Randomised Placebo Controlled Studies
- Many devices on the market claim benefits when combined with other practices such as meditation or breathing, which independently provide benefits such as relaxation, reduced anxious states, mood, stress, sleep. This fact makes it hard to discern whether claimed benefits are due to the device itself or the additional practice. What’s more placebo effect is a strong influencer on benefits of numerous devices. Only randomised placebo controlled scientific studies can demonstrate whether a device benefit is independent of the placebo effect. Make sure to verify quality of evidence provided by the manufacturer. Nurosym has demonstrated benefits independent of other practices in a number of Randomised Placebo Controlled Studies.

Bliss in a box
I got my Neurosym, it was very well packaged and took it out and was eager to get started. The First time i used it was the most incredible feeling, I felt everything relax in my body even my toes and fingers. I use it every day in the morning for 20min and in the evening for 20min and I am so relaxed.

Fabulous product and customer service
I have been a neurosym concert for 15 months after miss research about the importance of the vagus nerve. It is hard to say how well it works as when you use it, it isn’t tremendously obvious that anything is happening, but I happened to forget to take it on holiday this winter Abbas was without it for 6 weeks. By the time I got home, I was suffering from intense POTS crashes and generally very unwell. I quickly returned to using it and over time, I have stabilised.
To my horror, it stopped working in May. I contacted neurosym and after trouble shooting the issue, they sent me a brand new neurosym, free of charge. Finally a health company who is not focused on profits only

Poor customer service, earpiece lead faulty within 6 months
For the expensive price of the product you shouldn't expect anything to become faulty within 6 months of use which happened with mine. They do have 6 month warranty but I have tried contacting customer services many times via chatbot and email but I have simply been ignored. The product is ok when it works but poor customer service. Refuse to pay for a new earpiece lead when I've paid so much for the product already and they promote a six month warranty

Disappointed with this product
Disappointed with this product. It may have been helping my symptoms, but I never got the chance to find out. I'm a small person, and the device simply doesn't fit securely on my tragus. As a result, I either couldn't feel the stimulation at all or the electrode would slip off, making it difficult to use consistently.

Poor design and customer support
Purchased one week ago. The earpiece design is not great. a very small clip that is not very suitable for all ear/tragus types. As advised by Nurosym i have used soapy water and conductivity gel to improve the effect. However, The clip is constantly slipping off and does not offer much stability if you move around with it on (the malleable wire that goes around the ear keeps it on the ear, but does not stop the clip itself from coming off) They need to work on the earpiece design so it is a truly universal fit before charging £600 for it.
Only option on the website to contact Support was to a Livechat bot... When asked for an human agent, it said "The team will get back to you on this. Our usual reply time is a few hours" - Who has a few hours to sit there and wait with a live chat window open?
As for the performance of the device I cannot comment weather good or bad, as I have been unable to get a good run at it with the earpiece working consistently.
The idea is good... but i think you've rushed the design.
