Review Time
An overpriced TENS unit, heavily marketed on the new and dubious website scienceinhealth.com. However it’s also been praised by Bryan Johnson, which I believe is genuine and not paid hype.I have almost perfect biomarkers overall, with one exception: very low HRV, probably because of stress. My nightly average is around 21, measured with my Oura Ring.Because of that, I decided to give Nurosym a try despite the price. The device itself is well made and I genuinely like it. I’ve noticed slight improvements in my HRV, and I also get a relaxing effect when using it — similar to the feeling after a massage. I use it every day.Verdict after 4 weeks: I’ll keep it. You could probably find much cheaper TENS units with an earpiece that do something similar. But if money is not an issue, this one come in an easy-to-use and polished package that is refined for vagus nerve stimulation. If sold for 200€ it would be five stars. Will update this review after 6 month use.
I have sent several unanswered emails to the care at nuropod.com email address about my last week’s check in with no response and I also need instructions on submitting video to receive my rebate that was promised when I ordered the device.
"My experience with Nurosym has been very positive, and I have truly appreciated the product. It has significantly helped reduce my stress and anxiety levels. During spring 2025, I was going through a very difficult period and was feeling quite unwell, and Nurosym genuinely helped calm my nervous system. I have also noticed a clear improvement in my sleep quality since using the device.
I have had the nurosym device for a year. I have tried to use consistently as recommended in three separate spells including one very recently which is why I write my honest review now. The device is really unsuitable for some people- I did not have any of the risk factors described which could cause issues, but have experienced the same problems everytime I have attempted to get into a schedule of using the device. These problems are therefore not related to any getting used to the device as I was advised might be the case when I sought assistance. Unfortunately, my desire for the device to work initially took me outside of the return period as I really wanted to persevere and see if it would eventually be suitable. Since that time I have really tried to make it work on two other separate prolonged occasions. With every attempt, I started to get unexplained headaches and weakness and issues with my sleep duration. None of these were causing significant problems outside of my Nurosym use, so I feel these can clearly be attributed to use especially as they were apparent on all three periods of use. On every attempt, these receded with time after I stopped using the device, so I see an absolutely clear link. I have previously, many years ago, suffered from vestibular neuronitis. This left me with post vital fatigue for a couple of years but this had improved before my attempting to use Nyrosym. Perhaps this is the cause for unsuitability for me, it would be something I would be keen to better understand so I can see if non ear solutions may be better suited. I am happy for the manufacturer to get in touch if they want to know more about my experiences- I have trialled reducing time and intensity, everything i could think of to harness the devices benefits, but genuinely there is an issue in my case. I am glad to see that many others have experienced positive improvements but I feel the context of my experience may be useful for people to hear. I can only assess based on my own use and exeprience so can only fairly award 1 star.
I have ordered the device, used it for almost a month, unfortunately I did not experience the results I was hoping for so I got in touch to let them know about sending it back, they replied quickly, prolonged my 30 day period and provided accurate advice about the usage. After changing to the new protocol the device was still not what I was hoping for so I let them know about the refund intention again, they accepted the refund and the money was on my card 1 day after I've sent them the tracking for the parcel. This is what I call customer care, great job!
Amazing product worked immediately. However I have now had 2 devices which stopped working. I bought the second one as soon as the first one broke and it was an absolute nightmare getting a refund. Emails backwards and forwards at least 30 times from different support people. I have now had at least 9 replacement earpieces - some just stop working and most don’t work straight out of the box. I noticed a real improvement in my sleep and stress symptoms with the device but the stress of the constant back and forth plus constant emails that come automatically asking for my experiences and asking for these reviews has prompted me to write this. The support seems to be based in the US so don’t expect a reply on UK time either. I have much more to say but am hoping I will at least get a call from them today. At the moment my view is that it does work when it’s working! But my experience is that I have been in contact with them almost daily for at least a month so if you are trying to treat stress don’t bother!
The device is impractical. It turns off unexpectedly, and the earlobe wire is flimsy and unstable. No additional clip was added for secure attachment—aesthetics prioritized over function. Worse, the device itself has no clip, making it unwearable while moving. It is severely overpriced for what it offers.
Highly Recommended. I was drawn to vagal nerve stimulation after discovering my blood pressure was elevated and my HRV was poor. After researching the available devices it was clear that Nurosym was expertly developed and backed by multiple research publications. My experience with purchase and support has been excellent. The device feels of high quality with an excellent battery life. More importantly it has worked for me. It helps me feel relaxed, both my BP and HRV readings returned to normal within the first month of use. I will definitely keep using Nurosym every day.
I have been using Nurosym for more than a year. Easy to use on your own, extended battery (a lot of sessions before you need to charge). It is of great support in trying to find a balance with my health issues. Very nice and efficient team for customer support.
Hello,My wife and I bought Nurosym out of curiosity because we read about vagus nerve stimulation. As we have experienced problems with our intestines and stress management for some time, we decided it was worth a try. I had already been using cold showers and breathing techniques for some time, which helped me a lot. We have been using Nurosym for a week and have noticed a huge difference in our problems. We have noticed higher energy levels, improved digestion, higher HRV levels, improved sleep, and better stress management. We feel immediately calmer during and after the session, and we finally get a full night's rest. I haven't given up cold showers, but I have noticed an enhanced effect. I recommend Nurosym for people who want to support their recovery and for those with intestinal problems and stress.
