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.

Hi Elliot,
Thank you for sharing your honest feedback. We're really sorry to hear that your experience with Nuropod hasn’t met your expectations so far.
It looks like you were able to try our Nuropod device, and sometimes, results can vary depending on placement, protocol timing, or sensitivity settings. To make sure you get the most accurate and effective experience possible, we’d love to have one of our specialists reach out and provide a personalized protocol tailored to your goals and routine.
Many users who didn’t notice an effect at first have found improvements once their setup and schedule were optimized — we’d be happy to guide you through that process step by step.
Kind regards,
Parasym

I really like the Nurosym device
I really like the Nurosym device. But.. I received the Nurosym as a gift. After six or seven months the earpiece started to work less and less and finally it “died” ;) (although I was really careful with it!). I emailed them with the problem. They couldn’t help me out because I didn’t have an order number…and told me I just have to buy a new earpiece. Since it was a gift, I didn’t have those details!! Although I had the number on the device & another code on the official box that came with it, they couldn’t help me. Not very customer friendly! I had to buy new earpcies - 70 euros including shipping coasts!
And what if the device stops working? Then I also don’t get the 2 year warranty and have to buy a whole new Nurosym…
Adaptation: they reached out to me and refunded the new earpiece! And also arranged the 2 year warranty on the device, that’s awesome: 4 stars!

Staying out of Fight or Flight
Nurosym has been so helpful in getting me out and keeping me out of fight or flight. I use it upwards of 3 times a day for 30 minutes at a time. I find it easier to relax and to fall asleep. If I do wake up in the night or early early morning, I am often able to go back to sleep without much delay. I have less joint and muscle pain overall, but it has not yet completely resolved. I am very hopeful that with continued daily use I will be free of all pain in the next month.

Regeneration for Both Body and Mind
I’ve been using Nurosym for about a month, twice a day for 45 minutes — once in the morning and once in the evening.
After a short adjustment phase to find the ideal settings and electrode placement, it became an effortless part of my routine.
Since then, I’ve noticed major improvements in sleep efficiency, faster recovery from my daily strength and endurance training, and significantly better concentration during study and work.
My HRV readings (170–220 ms, measured with a chest strap) have improved noticeably, reflecting a calmer and more resilient nervous system.
Mentally, I’ve experienced a clear boost in resilience — challenges that used to feel stressful or intimidating have become much easier to handle, and my overall mental state feels more balanced and grounded.
Nurosym has proven to be a simple yet powerful tool to enhance both physical and mental regeneration.

It's works
I have been using for a month daily. I was sceptical but willing to try anything to manage symptoms of an autoimmune condition. I experience improvement in sleep time, rem and deep sleep. Improvement in hrv and less brain fog. They were not earth shattering huge but significant amd noticeable giving me a better sense of well-being. I will continue to use and highly recommend.

So far so good
So far so good.
I might write a review when I’ve had it a bit longer but…
I’ve had the device for 2 days and my HRV is up about 20% and I do seem to have moved out of fight or flight mode a little. I say that because I noticed I was yawning and since being locked in this post operation, post illness state of panic, I stopped getting proper sleep. That proper sleep was historically preceded by being tired, like properly naturally tired and that included yawning and that nice sense of relaxation. I haven’t had that for a long time.
So, with a combination of an HRV that’s raised from my very low baseline, and what felt like nights of normal sleep, it does seem to be having an effect.
Obviously I won’t be stopping any of my treatments with the doctors, I’m just using this to supplement them, and to help with the chronic anxiety I’ve been living with for around 9 months.

Poor Quality Periferals and Functionally Useless Warranty - Brilliant Customer Service
I have updated this review again siumply because the customer service has been brilliant and they are clearly being very pro-active about correcting the issue with the peripherals. Everything i have said below still stand but I wanted to say up top that the product really does work. We both have ADHD and using this at night time really helps regulate our sleep patterns; especially my partner who is particularly sensitive to the meds. The product does exactly what it says it does, i just wish the build quality for the price was better, which it appears they are working on.
We ordered one of their expensive £600 Nurosym device to help with winding down at the end of the day due to ADHD. The device has broken and the warranty is only 6 months. They now expect us purchase a £40 bit of cable (complete rip off) to check that the cable (6 month warranty) is faulty before they even check the device (2 year warranty).
Personally i think this is absurd. I have tools that cost £200 and come with a lifetime nbo questions aksed warranty. This collection of cheap materials and manufacturing processes however, can only stretch to 6 months. If you can find a similar device elsewhere then go with that supplier, at least if it breaks you're not on the hook for £600!!
UPDATE:
Nurosym were actually very proactive and have agreed to sed us the cable for free which is greatly apprieciated.
I do feel a V2 needs some R&D because looking at reviews this cable is obviously a common fault for £40 there is no strain relief or anything to stop the fragile cable stretching etc. for £10, fine i'd take the hit but £40 on something that doesn't last a year seems like not very good value

Thank you so much for sharing your feedback. We completely understand where you're coming from, especially after investing in something to support your wellbeing.
Just to clarify, the Nurosym device is covered by a full 24-month warranty, while the earpieces and cables have a shorter warranty due to normal wear and tear. That said, we truly appreciate your understanding and patience.
We’ve asked our team to reach out to you as soon as possible to review your case and make sure you’re fully supported. We genuinely value you as part of the Nurosym community and want to ensure this is resolved as smoothly and positively as possible.

Confidence restored
Started out with excellent customer service support for first few months but now my earpiece has failed after just 6 months and I am unable to get a reply from Nurosym customer services regarding getting a replacement
edited 7/10/25: Confidence in this company completely restored! I have now received a reply and a new earpiece should be with me tomorrow which is much appreciated and a fast response once contact was made. I must say that the customer service staff are always very helpful and courteous and Johnette in particular was so encouraging and helpful when I was trying to get used to the Nurosym in the early months. I am glad I have persevered with it and although I still have a way to go I am starting to see results. I only wish that the earpieces were longer wearing but hopefully my next one will last longer!

For me it’s life changer!!
I bought Nurosym because of very bad sleeping patterns. I used to wake up at 3 in the night, read a book for an hour or so and then asleep again.
Second reason was my tinnitus.
After a year of using (60 minutes before sleeping-at about level 20-25) I sleep like a child. No more sleeping pills, no waking up. Deep sleep till 7 am, when my dog wakes me up.
Regarding tinnitus, here I don’t see bettering. But also no worsening.
My only “concern” is, that I am becoming addicted (😂) on Nurosym as sleeping helper.
Overall I also feel more consistent in my mood changing, I really believe in Nurosym 👍
