From leading doctors and researchers to Olympic athletes — this is the daily routine for those who want to curb the biological impact of stress.

“I put a little electrode here in my ear. It stimulates my autonomic nervous system, trying to make my body more parasympathetic, more chill.”

“I wanted to know can we help our patients have an even more sustained relief from an out-of-control sympathetic nervous system. I'm happy to say so far the answer has been yes.”

The future of health is bioelectric and Nurosym is leading the way

Bryan Johnson's 14-step morning routine for anti-aging

“Nurosym studies suggest stimulating the vagus nerve can lower inflammation, improve sleep, reduce pain, lower blood pressure and increase heart rate variability, which is a biomarker of improved health.”

The bold new devices built to keep your brain young

2024

"Outside of ageing, Nurosym has been linked to an improvement in heart rate variability, improved tiredness and reduction in brain fog and depressive states."

"Parasym's neuromodulation tech is a breakthrough"

Why The Vagus Nerve Is So Exciting To Scientists

2023

“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.”

Zapping Vagus Nerve May Ease Post-Viral Tiredness Symptoms

“There is no trial of any drug or anything I’ve ever done in all my years that makes a patient so well that he or she no longer fulfills criteria for persistent fatigue syndrome”

Breakthrough Clinical Results from 60+ Clinical Trials

Reduction in anxious states

35%

Reduction in anxious states

*In a clinical trial, targeted stimulation of the vagus nerve increased vagal tone and inhibited cytokine production in the inflammatory process. Both are important mechanisms for anxiety resilience.

Reduced Fatigue & Increased Energy

48%

Reduced Fatigue & Increased Energy

*In the study, patients reported sustained improvements even one week after discontinuing the therapy, indicating prolonged relief from fatigue-related symptoms.

INNATE ENERGY & RESILIENCE

More active energy, stronger immune system

Your body’s ability to fight off illness and sustain energy depends on a well-regulated nervous system. Past infections or chronic stress can dysregulate your system leaving you fatigued, mentally foggy, and more vulnerable to illness.

Improvement in HRV
Clinical Study Results 18 %

Improvement in HRV

*In a clinical trial, a one-hour session of Nurosym favourably altered all parameters of Heart Rate Variability, when compared to a placebo. HRV indicates activation of psychophysiological self-repair mechanisms.

Reduction in sleep disturbances
Clinical Study Results 30 %

Reduction in sleep disturbances

In individuals with sleep onset difficulties, the sympathetic branch of the autonomic nervous system may exhibit heightened activity compared to the parasympathetic branch, resulting in increased agitation. The study demonstrated that Nurosym neuromodulation enhances parasympathetic activity, which in turn mitigates agitation and improves sleep scores. (Figure) Changes in sleep (PSQI Sleep Disturbance Score) across three timepoints: pre-intervention, 2-weeks, and 4-weeks (*p < 0.05).

Reduction in inflammation
Clinical Study Results 78 %

Reduction in inflammation

Inflammation throughout the body and brain contributes to disease development, progression, ageing, and mental health problems. In a randomised controlled trial of Nurosym neuromodulation, inflammatory cytokines were significantly lower in the group that received Auricular Vagal Neuromodulation Therapy (AVNT) compared to the placebo group at the end of 3 months.(Figure) The figure presents the changes in the IL-6 inflammatory biomarker compared to placebo.

RECOVERY & LONGEVITY

Reach Peak Biological Performance

Inflammation is the silent enemy to performance—it slows recovery from sports injuries, disrupts sleep, and accelerates cognitive decline. Poor sleep and chronic inflammation strain your heart, delay muscle repair, and weaken mental sharpness over time.


Nurosym is scientifically proven to:

  • Reduce Inflammation
  • Support cardiovascular
  • Enhance neuroplasticity

helping you recover faster, sleep deeper, and think sharper—so you can sustain peak performance every day.
