"Approved wearable devices are calibrated to be safe. Incorrect settings could slow or stop the heart. (It) involves running an electrical current close to your heart... Let’s not mess with that"
"The device that I've been clipping to my ear, called Nurosym, could provide an alternative means of stimulating the vagus nerve, and, unlike implanted stimulators, does not require surgery."
"The beat goes on: Bioelectronics reduce heart problems, palpitations and ringing in the ear"
"Anti-ageing neuro-tech: The bold new devices built to keep your brain young... Unlike implanted devices, these methods require the user to consistently and correctly apply the stimulation."

Serious adverse events in studies to date
FREQUENTLY ASKED QUESTIONS
Some of the most asked questions, answered
Are there any side effects associated with Nurosym?
As with any device, side effects are possible. However, we're happy to report that Nurosym is considered low risk when used as intended and boasts a very high safety profile. In fact, across all 50+ scientific studies conducted, there have been no reports of serious adverse events associated with Nurosym in studies to date.
While side effects are rare, it's important to be aware of potential experiences. The most commonly reported side effects include:
- Tingling on the skin where the electrode is applied (paresthesia/dysesthesia)
- Discomfort on the skin of the ear (Application site discomfort)
- Application site irritation/redness - if this occurs, try applying a bit of moisture before use, shorten session times, or switch ears
- In the initial weeks of use, a small proportion of users may also experience temporary effects that typically subside within 1-2 weeks of continuous use due to adaptation. These effects may include nausea, headaches, confusion, malaise, or weakness.
It's worth noting that in a published review of non-invasive neuromodulation clinical studies, only 2.6% of users discontinued therapy due to side effects.
Do you experience any distressing effects or transient effects beyond 2 weeks? We recommend discontinuing Nurosym use and contacting us via email for further assistance.
Can I use the Nurosym if I have an earring or a piercing?
We do not recommend using Nurosym if you have a piercing or an earring. We suggest removing the piercing, allowing the skin to fully heal for several days (up to a week), and then starting your use of Nurosym.
Can I share my Nurosym with others?
All Parasym clinical research has been conducted with each participant using their own personal device. To ensure the safest and most effective experience, we recommend that every individual user has their own device. Patient registration is done for each personal device to guarantee safe use.
If you do choose to share a device, we strongly advise using separate biocompatible components (such as earpieces) and ensuring that the other user is safe to use the technology.
Can I travel with my Nurosym?
Yes, you can! In fact, Nurosym can help relieve inflammation related to high altitude and jet lag, making it the perfect travel companion. Just keep in mind that Nurosym is powered by lithium-ion batteries, so most air travel safety regulations require that it be carried in your carry-on baggage only. For added safety, we recommend checking your airport's guidelines or asking an airport employee before your flight.
Can I use Nurosym if I have a pacemaker or other medical implant?
Nurosym should not be used if you have any active implanted device, including electronic or medical devices such as a pacemaker, cochlear implant, cerebral shunts, or invasive vagus nerve stimulators. Additionally, if you have non-active implants that may potentially interact with the nervous system, such as metal implants, it's important to consult with your healthcare professional before using Nurosym. Users with known severe coronary disease or recent myocardial infarction (within 5 years), as well as pediatric patients, should also seek medical advice before using Nurosym.
Are there any ongoing research or studies about Nurosym?
Yes, indeed! Nurosym is at the forefront of scientific research, continuously investing substantial resources to advance neuromodulation technology. With over $10 million dedicated to studies, we collaborate with over 60 esteemed organizations, including Harvard and UCL, to deepen understanding and improve outcomes.
Our research has resulted in 50+ peer-reviewed papers in leading journals such as Nature and Nature Reviews Cardiology. This includes a meta-analysis of placebo-controlled cardiac studies in JACC, a highly reputable journal with a 21.7 impact factor, ranking among the world’s top 100 journals. These studies highlight exciting breakthroughs in modulating Vagus Nerve Activity, Heart Rate Variability, and more.
We’ve made study findings accessible on our Scientific Evidence page, summarizing key insights for ease of understanding. While many journals use paywalls or technical language, our scientific team has synthesized the information for broader accessibility. Healthcare professionals can also apply for curated access to all our papers through this link.
Benefits of Nurosym Research
Extensive studies have uncovered remarkable benefits, including:
- 61% increase in Vagus Nerve Activity in 5 minutes
- 18% increase in Heart Rate Variability
- 13% improvement in sleep
- 48% improvement in fatigue
- 40% improvement in post-viral fatigue symptoms (e.g., brain fog, pain, GI symptoms)
- 78% reduction in inflammation
- 32% improvement in memory and 29% in reading
These results showcase why Nurosym is widely regarded as the gold standard in neuromodulation.

Can I use Nurosym while sleeping or exercising?
We do not recommend using Nurosym while sleeping or exercising due to safety considerations. It's important to use Nurosym in a controlled environment where you can remain aware of its effects. Always prioritize your safety and well-being when using Nurosym.
Nurosym is designed to be versatile and convenient, allowing you to wear it during various activities such as reading, working, cooking, meditating, watching TV, or socializing. We recommend incorporating Nurosym into your daily routine, aiming for 60 minutes per day to experience its beneficial effects, which can be felt in as little as 5 minutes. Using Nurosym before bed can help improve sleep quality. Additionally, you can use Nurosym as needed during or after stressful events or workouts to aid in faster recovery, during meals to assist with digestion, or for pain relief.
Are there any specific conditions that must be met for a return to be accepted?
In order for a return to be accepted, your item should be in its original condition and packaging, just as you received it. Don't forget to include the receipt or proof of purchase along with your return request.
Can Nurosym be used alongside other therapies or medications?
Nurosym can be a complementary tool alongside other therapies or medications for many individuals. However, there are specific contraindications to consider. These include:
- Users who have undergone surgery to cut the vagus nerve (cervical vagotomy)
- Users diagnosed with severe bradycardia
- Users with a permanent implanted metallic or electronic device or jewelry in close proximity to the ear tragus
- Pregnant women
Additionally, certain situations may be contraindications unless under the supervision of a healthcare professional, such as users with any active implanted device, severe coronary disease or recent myocardial infarction within 5 years, and pediatric users.
It's crucial to consult with a healthcare professional to assess whether Nurosym is safe and appropriate for your specific circumstances, especially if you fall under any of these categories. Your healthcare professional can provide guidance on potential precautions or supervision needed during Nurosym use. If you do not have a healthcare professional you can contact, please reach out to our support and we’ll help connect you with the right person.
Can I use Nurosym while pregnant or breastfeeding?
We haven't evaluated the use of Nurosym in pregnant women during scientific studies. To ensure safety, we recommend consulting with your healthcare professional to determine if vagus nerve stimulation is appropriate for you during pregnancy or while breastfeeding.
