• Counter post-viral symptoms, like fatigue or brain fog.
• Maintain optimal HRV, recovery and reduce cardiovascular health risks.
• Relax and stabilise your mental state to help you fall asleep faster, achieve high-quality sleep, wake up more with more energy and fewer negative thoughts.
• Improve digestive function by promoting healthy communication through the gut-brain axis.
• Reduce inflammation, pain and discomfort linked to your nervous system.
• Strengthen cognitive performance & focus to counteract the effects of aging.

How does Nurosym achieve all of this? 

Nurosym is a wearable medical device that sends electrical impulses to the brain via the vagus nerve to alleviate symptoms of dysregulated nervous system. Modern science has discovered that many chronic mental & physical symptoms are linked to chronically dysregulated nervous system. The nervous system and one of its largest nerves - the vagus nerve - controls all body functions, from breathing, heart rate, digestion to energy, calmness and mood. When the vagus nerve is not functioning properly, organs & systems of the body don’t work in harmony leading to poor physical & mental health. By strengthening the nervous system in a natural way through modulating the activity of the vagus nerve, Nurosym helps restore balance to the mind and body. 

Nurosym exerts its effects through various mechanisms:

• It triggers the “rest and digest” response, promoting relaxation, lowering heart rate and improving digestion.
• Reduces inflammation markers leading linked to pain & overactive immune response
• Decreases oxidative stress markers linked to chronic diseases and ageing.
• Increases neuroplasticity, rewiring the brain for better mood, better motor & cognitive learning and recovery from neurological conditions.

This way Nurosym supports mental & physical health and helps alleviate symptoms of a range of symptoms.

Nurosym is a certified medical device delivering proprietary Auricular Vagal Neuromodulation Therapy (AVNT)™ developed by Parasym, scientifically validated and optimised in 40+ scientific studies conducted in partnership with leading scientific research institutions including Harvard and UCLA.

Nurosym is the only certified medical device approved for the purpose of targeting the vagus nerve via the ear available without prescription. It is the most studied neuromodulation system of this kind, widely considered as the gold standard in scientific neuromodulation research.

These symptoms have been linked to autonomic nervous system imbalance and Vagus Nerve Impairment:

• Anxious states and Stress related symptoms
• Chronic Tiredness, Fatigue, Brain Fog, Burnout
• Digestive issues, irritable gut reflux, diarrhoea, constipation, bloating
• Sleep problems
• Negative thoughts
• Inflammatory symptoms
• Pain, headaches
• Memory & Attention problems
• Postural Heart Rate Abnormalities or fainting
• Post-Viral Symptoms
• Widespread body pain

Our latest research data also suggests Nurosym improves learning and short-term memory and cognition.

Nurosym also has been shown to promote relaxation, mood, sleep, healthy digestion, increased HRV, as well as to alleviate symptoms of stress, burnout, adrenal fatigue.

Parasym research is also investigating the impact of Auricular Vagal Neuromodulation Therapy on athletic performance, muscle recovery, weight management problems, substance dependency and more.

• Users who have undergone surgery to cut the vagus nerve (cervical vagotomy);
• Users diagnosed with severe low resting heart rate;
• Users with a permanent (that cannot be removed before using Nurosym) implanted metallic or electronic device or jewellery at close proximity to the ear tragus;
• Pregnant women.

Below are listed situations that are also contraindications unless the user receives a different health opinion on the device use by their health professional and is under the supervision of a health professional while using the device. If you fall under one of these categories, your health professional might advise whether, in your specific case, the device is safe to use, potentially following certain precautions or under specific supervision:

• Users with any active implanted device (including electronic and/or medical devices) e.g. cochlear implant, cerebral shunts, invasive vagus nerve stimulators, pacemakers or non-active but potentially interacting with the nervous system (e.g. metal implants);
• Users with known severe coronary disease or recent heart attack (within 5 years);
• Paediatric users

1. Pregnant women have not been evaluated in scientific studies.
2. Both paediatric users and users with pacemakers have been enrolled in scientific studies with Parasym technology, and no device related adverse events or interferences have been observed so far in the scientific setting.

Nurosym has partnered with 60+ research institutions, including UCLA and Harvard, to conduct scientific studies to validate the health benefits of Nurosym.

Our research is founded on these principles:

• Parasym’s studies are led by independent university experts, with no financial ties to us, unless explicitly mentioned.
• Our research is externally funded, ensuring unbiased and genuine results.
• We value transparency: All our study findings (positive or otherwise) are open and accessible to everyone.
• We collaborate with distinguished physicians and scientists, ensuring the pinnacle of research quality.
• At Parasym, we adhere to the highest scientific standards, consistently achieving significant and trustworthy results in the most stringent tests. A large part of our scientific evidence comes from Randomised Placebo-controlled Scientific Studies, which are considered the highest standard of evidence.

Watch Dr Denef explain how to use Nurosym:

How to use Nurosym in a few steps:

1. Apply a bit of moisture on the tragus.
2. Wear the earpiece correctly on your left tragus, the cable should go over and behind your ear to keep the electrodes in place.
3. Turn on Nurosym
   Slowly increase energy level until you feel a light tingling sensation in your ear.
4. Notice how pleasant the sensation of neuromodulation feels. This is a signal that the current is flowing and that your parasympathetic nervous system is activated.
5. Sit or lie down with the device or perform daily activities while Nurosym works to strengthen your parasympathetic nervous system, decrease inflammation, oxidative stress and activate neuroplasticity to help you feel better.
6. Notice the sensations of calmness, relaxation, decreased stress, improved mood, more energy flowing into your body.
7. If you feel the sensation intensifies over time or you stop feeling it, adjust the energy level until you feel a light pleasant tingling sensation again.
8. Continue using Nurosym every day for 30-60 mins a day, preferably in the morning or split between morning after waking up and evening before sleep and enjoy better health & mood.

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, 30+ 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 treatment 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.
