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.

Nurosym is a complete game changer

Nurosym is a complete game changer. I was stricken with Long Covid in mid 2020 and have battled it in every way you can imagine, getting virtually nowhere. Now since starting to use my Nurosym daily in November 2024 I have been SO much better in terms of energy, mood, sleep, gi symptoms etc etc.
I found that if I followed the recommendation of using the device at night before bed I had zero sleep for those nights. Contacting Nurosym I received fast support advising using the device in the morning. Since then, excellent sleep.
Any problems or concerns, customer care are speedy, helpful and efficient. I cannot fault Nurosym or their team. Excellent investment.

Worth every penny

I suffer with chest pain from anxiety and often feel like I'm in survival mode. I also suffer with acid reflux, inflammation, irritability and difficulty focusing. Since using Nurosym, my acid reflux is non existent and I feel much calmer and able to deal with day to day life. I use Nurosym once in the morning and once in the evening. It's worth noting I also combine Nurosym with breathing techniques to help calm my nervous system. Although Nurosym isn't cheap, I genuinely believe it's worth every penny and I definitely notice a difference when I forget to use it.

Hi Kate,

Wow, this is such a meaningful review. We know how overwhelming anxiety and living in constant survival mode can feel, so it really means a lot to hear that Nurosym has helped you feel calmer and more able to manage daily life.

It’s especially encouraging to hear about the improvement in your acid reflux and how combining Nurosym with breathing techniques has supported your nervous system. It’s great to hear you’ve found a routine that works for you.

We truly appreciate your trust and openness. Thank you for taking the time to share your experience.

Horrendous tinnitus and no benefits

I purchased a Nurosym device in the autumn to hopefully help with chronic pain and inflammation issues. I used it as recommended, initially twice daily for around two months, always staying within the suggested settings.

During this period, I became aware of increasing tinnitus in my left ear, which is the side where the device connects. As the tinnitus worsened, I reduced both the intensity and frequency of use, eventually cutting back to once a week. Despite stopping use altogether, I now have constant, deafening tinnitus in my left ear that does not go away. This was not something I experienced before using the device.

I contacted Nurosym support several times about this. While the responses were polite and well written, they were clearly AI-generated. My concerns were later “escalated” to a named AI doctor who, when searched for online, appears to be a doctor persona they use. I found this extremely disingenuous. I would much rather receive an honest reply stating that responses are AI-generated or hear directly from a real person who has considered my feedback, rather than being given the impression of escalated medical oversight that does not exist.

I received a discount to take part in what was described as a study. I did not expect a clinical trial, but I did expect something more substantial than what turned out to be a very light-touch online survey that did not meaningfully explore side effects or outcomes and did not appear to have any subsequent interactions planned. This has left me with the impression that the “study” element is more of a marketing exercise than a genuine attempt to gather robust user data.

Unfortunately, I experienced no positive benefits from the device, despite the significant cost. What I am left with instead is permanent, intrusive tinnitus that now affects everyday activities. I have noticed other users reporting worsened tinnitus. I’m concerned that this risk may be underrepresented in public reviews.

I am genuinely gutted that this device did not help me, but I feel strongly that potential users should be aware that tinnitus can be a serious side effect, even when the device is used within recommended guidelines. This is something I may now have to live with long-term.

I am sharing this review simply to ensure others can make a fully informed decision.

Surprisingly effective from day one

A company that honors its no-risk 30 day guarantee!

Usually, when a product doesn’t give you the benefits you were looking for, you don’t give the company 5-stars. On the company’s website, they were upfront about some people having great success with the device and some people experiencing moderate benefits. I could see benefits to the device, but not to the extent I was hoping for.
They know that the device will have varying degrees of success for individuals, so they offer a 30 day money back guarantee. They couldn’t have been more expedient in processing my refund. They just wanted a brief reason why it didn’t meet my expectations, and that was it! No haggling or questioning. So, if you want to see if the device is for you, go for it! I you’re not satisfied, you will have no problem getting your money back.

Buyer Beware! Earpiece isn’t covered by 2 year warranty

The cable / connector of my earpiece stopped working after 7 months and 20 days. I contacted support and was told the earpiece warranty was only 6 months and I would have to buy a new one - for £45!

The earpiece, is poorly made with a flimsy cable and connector attachments. The unit is completely useless without the earpiece and only Nurosym earpieces can be used. The manufacturer is not transparent that the earpiece is only covered by 6 months warranty and costs £45 to replace.

Be prepared to regularly pay for new ones!

Hi B.J.,

We hear your frustration. Earpieces can be affected by normal wear and tear, which is why the warranty period is shorter than for the main device. This information is provided both on our website and in the user guide to help customers understand coverage and replacement costs.

That said, we want to make sure you get the support you need. We asked for more of your information as we will be reaching out to provide further assistance and explore the best way to help. Thank you for sharing your feedback. It helps us improve and better support our users.

Hi Marci,

Thank you for sharing about your experience and we hear your frustration. Someone from our clinical team will reach out to better understand your situation and address your concerns.

We'd like to share that multiple clinical studies have been conducted testing Nurosym technology in patients with Long Covid, including research by Zheng et al ( 2024) and by Verbanck et al. (2021); such studies show that non-invasive vagus nerve stimulation (VNS) delivered by Nurosym can be effective in ameliorating Long COVID symptoms, such as fatigue, cognitive issues, and sleep problems with low risk of mild discomfort. However, responses can vary based on individual characteristics.

We take your feedback seriously and will follow up to support you and learn from your experience.

This product is absolutely amazing. So far I’ve seen positive impacts into almost all areas that nurosym states it helps with.
