Explore the Science Behind Nurosym

Learn how your nervous system operates and why Nurosym's precise activation of a single nerve can unblock your body’s ability to calm down, recover, and perform at its peak.

Nervous System Dysregulation: The Silent Pandemic You’ve Never Heard of

Millions worldwide suffer from chronic fatigue, anxiety, and digestive disorders, often finding little relief despite consulting multiple doctors and trying various treatments [1]. Experts are contributing this to an imbalanced nervous system.

Nervous system responses - Fight or Flight vs. Rest and Digest

Recent research shows that many of these persistent health issues stem from nervous system dysfunction [2]. Our bodies naturally manage stress using two key components:

The Sympathetic System (“fight or flight”) prepares us to handle threats and challenges. The Parasympathetic System (“rest and digest”) promotes healing and balance. Together, these systems keep us healthy and adaptable [3].

The impact of chronic stress

When faced with constant stress, the nervous system becomes overwhelmed. This leads to excess cortisol, inflammation, and damage to various organs, causing brain fog, fatigue, anxiety, and widespread health problems [4].

Restoring balance between systems

Rather than treating individual symptoms, restoring harmony between the sympathetic and parasympathetic systems is crucial. By doing so, the body’s natural healing mechanisms can function as intended, promoting overall well-being [4].

Understanding and addressing the nervous system today is unlocking new paths to lasting well-being and Nurosym is at the forefront with over a decade of empirical research and careful study of Vagus Nerve mechanisms.

What is the Vagus Nerve?

The vagus nerve plays a vital role in your body’s ability to maintain balance and manage stress. As a primary component of the parasympathetic nervous system, it helps regulate "rest and digest" functions that are critical for your well-being.

Plays key role in relaxation: When the brain receives sensory information it uses the vagus nerve to carry activation signals to various organs, telling your body to relax [5].

Maintains balance and homeostasis: The vagus nerve regulates vital functions such as heart rate, digestion, immune response, and emotional regulation in response to stress, maintaining homeostasis [5].

Runs through the whole body: With a vast network of 100,000 distinct fibers, the vagus nerve influences multiple physiological processes. Even minor disruptions can have significant impacts, potentially leading to undesired symptoms ranging from anxiety and chronic fatigue, to heart palpitations, or even autoimmune conditions [6].

Supporting vagus nerve health can dramatically improve your body's stress response, resilience, and adaptability since so many health conditions can be linked to nervous system dysregulation [6].

Vagus Nerve Stimulation as a Pathway to Health

Vagus Nerve Stimulation (VNS) means sending targeted electrical signals to specific fibres of the vagus nerve to positively affect the body’s physical and mental state [7].

For decades, doctors have explored the potential of stimulating the vagus nerve to address a wide range of physical and mental health conditions.

How It Works

Similar to how a pacemaker regulates the heart, VNS sends electrical signals to specific vagus nerve fibers to restore normal nervous system function. This therapy has shown promise in treating conditions previously resistant to conventional treatments [7].

From surgery to the first non-invasive device

Initially, VNS required invasive surgery, making it accessible only for severe cases. However, in 2020, Nurosym released the first certified non-invasive device, capable of achieving similar effects, but eliminating the need for surgical procedures [8][9].

Nurosym in-house technology

Nurosym uses Auricular Vagal Neuromodulation Therapy (AVNT), targeting the tragus of the ear for effective and safe stimulation of vagus nerve fibers [9][10]. This approach was empirically developed for over a decade by our team of leading neurologists and clinical researchers to ensure high efficacy while minimizing side effects.

Clinical validation and research

The effectiveness of Nurosym has been confirmed through over 40 peer-reviewed studies with prestigious institutions, including Harvard, UCLA, and the NHS. Clinical results have shown measurable improvements, such as reduced inflammation and enhanced cardiac function [9].

Regulatory approval and accessibility

Nurosym has received CE certification as a medical device and can be purchased without a prescription, making it available for both patients and healthy individuals [9].

Adoption and medical community consensus

Tens of thousands of people now use Nurosym on a regular basis, and hundreds of healthcare professionals recommend it as part of clinical treatment protocols.

With Nurosym, you can harness the transformative power of the vagus nerve from the comfort of your own home. Backed by extensive research, we offer a 30-day money-back guarantee, so you can try Nurosym risk-free and take control of your health.

Benefits of Vagus Nerve Stimulation

Vagus nerve stimulation is FDA-approved treatment for epilepsy, migraines, and treatment resistant depression. It has also been clinically proven to relieve a host of different health conditions and symptoms including [11]:

  • Chronic fatigue
  • Reduced Heart Rate Variability (HRV)
  • Depression
  • Anxiety
  • Digestive issues
  • Respiratory issues
  • Inflammatory conditions
  • Cognitive impairment
  • Low mood
  • Chronic pain
  • Migraines
  • Sleep issues

The Importance of Precision in Vagus Nerve Stimulation

Despite popular opinions on social media, activating the vagus nerve in a correct way without side effects is not an easy task. 

Imagine trying to tune an old-fashioned radio dial to a specific frequency. The radio has a broad range of stations, but only one frequency offers the clear, balanced sound you're looking for.

This analogy perfectly illustrates the challenges in vagus nerve stimulation (VNS) therapy. The vagus nerve has 60 fibers, each representing a specific frequency linked to various bodily functions.

The difficulty lies in targeting the correct fibers at the precise time and through the appropriate access points to achieve therapeutic effects without causing unwanted side effects [12].

Ensuring The Highest Quality Testing and Safety Standards

Since 2014, we've tried to better understand the complex and crucial role the vagus nerve plays in overall health.

Selective and safe vagus nerve stimulation has been at the core of our mission, given the nerve's extensive role and complex network of approximately 100,000 fibers.

  • Anatomical complexity: The vagus nerve originates in the brainstem, extends through the neck, and connects to multiple organs. Nurosym has been rigorously tested not to impede fibers carrying important signals influencing everything from heart function to emotional well-being [13].
  • Therapeutic targeting: Nurosym delivers electrical impulses only to specific fibers proven to produce targeted effects, thus capable of addressing conditions like epilepsy, depression, heart disease, and inflammatory disorders [13].
  • Preventing side effects: Since the vagus nerve affects all major organs, incorrect stimulation can actually lead to side effects, such as palpitations. Nurosym is continuously tested across all key biomarkers and has recorded zero reports of serious adverse effects in study populations.
  • Optimal access points: The auricular branch in the ear, composed mainly of sensory fibers, is a safer option of accessing the vagus nerve compared to the neck, which has a delicate mix of sensory and motor fibers. The tragus is especially effective for VNS, offering a high density of afferent fibers near the skin surface for precise, natural activation of the parasympathetic nervous system [14].

Modulation vs Stimulation

When it comes to the vagus nerve, more stimulation isn’t always better. Achieving effective results requires precision and careful control to avoid unintended consequences.

  • Precision is Crucial: Like tuning a radio to the right frequency, vagus nerve stimulation needs to be adjusted to each person’s unique nervous system. The optimal settings vary day by day and between individuals. Excessive or imprecise stimulation can disrupt the nervous system and cause harmful side effects, even leading to permanent damage.
  • Certified Medical Devices Matter: To ensure safety, only rigorously tested medical devices should be used for vagus nerve stimulation. Nurosym stands out as a certified device, having passed extensive safety studies and met stringent EU regulatory standards for quality manufacturing.
  • Regulatory Validation: Nurosym has been evaluated as a Non-Significant Risk device in multiple clinical trials by the FDA, highlighting its commitment to safety.
  • Tailored Modulation: With 45 adjustable energy levels, Nurosym provides precise control, allowing each user to customize settings for optimal effectiveness and nervous system balance.

Your vagus nerve is invaluable, and using a trusted, certified medical device like Nurosym ensures safe and effective modulation tailored to your individual needs.

Convenience without gel

Vagus nerve stimulation is now more convenient than ever, thanks to innovative technology that eliminates the need for messy conductivity gels.

  • Problem with traditional methods: Normally, electrical stimulation requires a conductivity gel to counter the skin’s constantly changing electrical resistance. However, gels can be messy and inconvenient, especially for frequent use.
  • Nurosym's technological solution: After a decade of clinical research, Nurosym developed a neuromodulation system that eliminates the need for gel. The technology uses a hypoallergenic, high-conductivity material that is both biocompatible and effective at transmitting current through the skin.
  • Safe and effective: This advanced material ensures efficient current delivery while minimizing the risk of skin irritation or damage, offering a hassle-free experience for regular use.

The gold standard in clinical research

  • Nurosym is a certified medical device, with over $10M deployed in clinical trials, 60+ partner research organisations including Harvard, UCL, and UCLA 30+ published papers in leading journals covering our exciting and clinically significant results.
  • This is why Nurosym is the leading non-invasive vagal neuromodulation system used in clinical neuromodulation research.

Certified medical device with confirmed safety

  • Exposing your nervous system and brain to untested electrical currents can put you at risk of 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 clinical 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 treatments that present online reviews instead of clinical evidence. It’s vital to carefully verify if a treatment you’re evaluating is registered as a medical device, which certifies it is safe and effective to use.
  • When considering any health intervention, be sure to evaluate the status of certification, clinical evidence, warnings and seek advice of trusted healthcare professionals.
  • Nurosym is one of a few registered neuromodulation-based medical devices with safety confirmed by regulatory bodies in the EU and in Randomised Placebo Controlled Studies.
  • Nurosym has a CE Mark in the EU and has been awarded FDA Non-Significant Risk Designation in multiple studies, which both signify the safety of our device.

Proven Target Activity

  • In addition to safety, it is crucial to consider the efficacy of a given device.
  • The fact that a device is delivering a safe electrical current is not enough. It also needs to demonstrate that it specifically stimulates the intended nerves and activates them as well as a specific stimulation site on the body closest to a particular branch of the vagus nerve. [16].
  • Without clinical data, we cannot know if a device is actually stimulating the right neural pathways and avoiding stimulating unintended neural pathways.
  • Nurosym has been demonstrated in placebo-controlled clinical studies to therapeutically activate the vagus nerve, as well as improving Heart Rate Variability (HRV). Our proprietary signal delivery that exerts these effects has been developed over 10 years of laborious research with a total cost of over $10M.

Efficacy Confirmed in Randomised Placebo-Controlled Studies

  • The placebo effect has a strong influence on the benefits of numerous devices. Vagal tone (or HRV) is influenced by many factors including our thoughts, and therefore placebo effect. Only randomised placebo-controlled clinical studies can demonstrate whether an intervention's effect is independent of the placebo effect. Make sure to verify the quality of clinical evidence provided by the manufacturer [17].
  • Nurosym has demonstrated benefits independent of other practices in multiple Randomised Placebo-Controlled Studies.
