innate energy

Get back your active energy

Burnout, chronic tiredness, 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.

Health & Longevity

Reach your peak performance

Greatness 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 has shown the ability 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.

Health professionals opinions

The Parasym AVNT technology is a general wellness product which means it can affect your nervous system. It emits specifically designed electrical impulses to the brain, through this clip, which attaches to tragus of your ear which affects the auricular branch of the vagus nerve.

I've found two big benefits for Parasym AVNT technology wellness product. I found that it certainly helps me focus, there are studies definitely to support that and I've found that it improved my HRV when I've measured it.

There is this wellness product that you just clip on your ear one hour each day and it improves your concentration, your sleep, your overall mood and it reduces your anxious states and low mood and many more things.

I've been using Parasym AVNT technology with my users and at home. I found the concept of vagus nerve stimulation online, and it seems helpful for users with widespread body pain, chronic tiredness, or post-viral fatigue symptoms.

I'm a cranial sacral therapist from Vancouver, Canada. After seeing great progress in a client using Parasym AVNT technology, I tried it for myself. It helped regulate my sensitive nervous system, and after an initial adjustment period, I noticed significant improvements

Why the vagus nerve is so exciting to scientists?

Overrides the stress response. Endless notifications, tight deadlines, and constant demands keep your body in "fight or flight", leading to chronic stress

Signals the body it's time to recover. Start restoring balance within minutes. Train your body to be more resilient and adaptable to long-term stressors

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.

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.

Reduction in anxious states
Clinical Study Results 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
Clinical Study Results 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.

Improvement in HRV & Vagus Nerve activity

Improvement in HRV & 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.
