Clinical studies proving benefits and efficacy
Sleek, wearable device that rewires your brain-body communication
Nurosym delivers precise electrical impulses to activate the vagus nerve, a key part of the parasympathetic system that restores nervous system balance.
DEVELOPED BY EXPERT NEUROLOGISTS AND LEADING RESEARCHERS TO
Repair your nervous system
Calm down your mind
Our hyper-connected world keeps your mind always on. Back-to-back notifications, deadlines, and tasks make it hard to switch off, leaving your body stuck in “fight-or-flight.” Over time this leads to chronic stress symptoms which are hard to target. Nurosym helps downregulate your stress response to start restoring balance within minutes. Train your body to handle stress naturally—without overwhelm.

"The constant push to deliver more work destroyed my organism. Each time I was putting the device I could release tension from my nervous system."
- Anxious states 35% improvement
- Oxidative Stress 28% reduction
- Mood score 45% improvement
Get back your active energy
Burnout, chronic fatigue, dizziness, and pain make even simple tasks feel exhausting. When your nervous system is out of balance, stress lingers, inflammation rises, and recovery slows—leaving you drained no matter how much you rest. Nurosym helps reset your autonomic function, reducing inflammation and improving vagal tone, so you wake up refreshed, stay energized, and feel resilient all day.
Francesca, UK
"Honestly, l've seen such a big difference. I don't have as many days where I'm so exhausted I can barely move"
- Fatigue 48% improvement
- Postural Heart Rate Abnormalities 40% improvement
- Macrocirculation 50% improvement
Reach peak performance
Peak performance isn’t just about pushing harder—it’s about recovering smarter. Poor sleep and inflammation strain the heart, slow recovery, and accelerate cognitive decline. Nurosym is scientifically proven to reduce multiple inflammatory markers, support HRV and cardiovascular health, help recovery from sports/injury, and aid neuroplasticity- so you can heal faster, think sharper, and sustain long-term resilience.

"I've experienced ... improved recovery metrics as measured by my WHOOP device, and an increased ability to focus or train for long periods of time."
- Heart Rate Variability 18% increase
- Inflammation 78% improvement
- Sleep 19% improvement

Anesthesiologist & Medical Director at Clarus Health
"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."
Dr Myro Figura
Anesthesiologist & Chief Medical Officer at HealFast
"(Nurosym) increases the rest and digest side of your nervous system by up to 50% in five minutes and it's a potent reliever for anxious states."
Dr James Gill
Associate Professor at Warwick Medical School & General Practitioner
"I found (publications) with no declared conflict of interest by Leeds University. They demonstrated reduced sympathetic nerve activity. Personally, (with Nurosym) my HRV increased from 40s to 69."

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.
-
Counter Burnout & Chronic Fatigue
Fatigue is the body's response to prolonged stress and systemic inflammation. Nurosym restores autonomic balance, reducing inflammatory fatigue and supporting sustained energy production.
-
Strengthen Immunity & Reduce Inflammation
A dysregulated nervous system weakens immune defenses and makes us susceptible to illness, post-viral symptoms, and slows recovery from infections. Stimulating the vagus nerve unlocks parasympathetic activity and regulates immune function.
-
Reduce Brain Fog & Dizziness
Infections come with disruption in cognitive function and inability to focus caused by poor blood flow and brain inflammation. Support clearer thinking by improving brain oxygenation and accelerating neural recovery.

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

Gastrointestinal Symptoms (Acid Reflux, Irritable gut, Inflammatory gut, Gastroparesis)
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
*In the study, patients reported sustained improvements even one week after discontinuing the therapy, indicating prolonged relief from fatigue-related symptoms.
Improvement in HRV and Vagus Nerve activity
*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.
