Vagus Nerve Stimulation for a Better Health

Experience Relief from Brain Fog, Fatigue, Anxiety, Depression, Sleep Problems, Inflammation, Digestive Problems and More

Let’s talk about Neuromodulation.

Neuromodulation is a technology that works directly on the nervous system.

By sending targeted signals to specific neural circuits in the body via the vagus nerve – it’s possible to change your body’s physical and mental state and improve your overall quality of life.

It works through a similar process that cardiac pacemakers use to correct abnormal heartbeats; by re-establishing the normal function of the nervous system.

Doctors have been fascinated by the potential of using electrical impulses for therapeutic benefit for decades and recent clinical studies have had exceptional results.

Neuromodulation is a clinically proven approach to relieve a host of different health conditions and symptoms including depression, fatigue, anxiety, and stress.

When it comes to managing chronic fatigue, low mood, and low energy and more, we’ve entered a new era of treatment.

Neuromodulation Methods

However, not all neuromodulation methods are created equal, and it’s essential to consider the risks associated with different treatments, electrical currents and approaches.

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. Precise, calculated delivery of electrical signals to the right place at the right time, taking into account the access point in the body and your specific autonomic nervous system activity levels are crucial factors to safely delivering Neuromodulation.

Ensuring safety and efficacy requires extensive clinical studies that cost milions of dollars. This is why few Neuromodulation devices have been certified by health regulatory bodies as safe and effective.

When considering any health intervention, be sure to evaluate the status of certification, clinical evidence, warnings and advice of trusted health care professionals.

Beware of websites claiming to deliver benefits from uncertified treatments that present online reviews instead of clinical evidence. Carefully verify if a treatment you’re evaluating is registered as a medical device, which certifies it is safe and effective to use.

Transcutaneous Auricular Vagus Nerve Stimulation

Neuromodulation up to this point has only been possible with implantable devices, requiring risky and costly surgery, painful medications and months of recovery.

Until now…

After spending 8 years in development, deploying over $10M in clinical research alongside the world’s leading clinical research centers (UCLA, Harvard and more), we’ve created the breakthrough product that’s been missing.

A clinically proven, medically certified, approved by regulators, extensively tested during over 2 million patient sessions, a drug-free, safe, easy, cost-effective at-home therapy device that gives you the power to get your life back.

Clinical Data

1hr Nurosym Session

One hour session of Nurosym favourably altered all three parameters of Heart Rate Variability (HRV), when compared to placebo.

Figure (a) shows High Frequence HRV is significantly increased ('p=0.001). Figure (b) shows Low Frequency HRV is significantly decreased ('P=0.001). Figure (c) shows the ratio of LF to HF is significantly decreased (*p=0.002).

HRV is an indicator of Vagus Nerve activity. Improving these parameters of HRV indicate targeted stimulation of the vagus nerve and activation of specific mechanism that reverse chronic fatigue and improve mood.

Symptom Intensity including brain fog and fatigue

A very significant improvement was observed after 10 treatment sessions. (D0 vs. D10: p<0.0001)

We evaluated our proprietary Neuromodulation on those suffering with Long-COVID symptoms such as Fatigue, cognitive problems, Depression, Pain etc. Treatment starts after baseline measurement at Day 0 (D0), ending on D10, with follow up measurements one week later (D17).

Reduced Fatigue

There was a highly significant improvement in fatigue scores after treatment (D0 vs. D10, p<0.0001).

Fatigue was measured using the Pichot Fatigue Scale. Participants reported that the improvements in fatigue remained 1 week after stopping the treatment.
