Message from Parasym research labs

In 2004, our expert European team of neuroscientists, neurologists, and clinical researchers united with a singular goal: to develop accessible, evidence-based neuromodulation to improve the health of 1 billion people.

For ten years we engineered Nurosym AVNT™ and fine tuned its signal delivery. Today, we are proud to have achieved the precision necessary to deliver up to 61% vagus nerve activation within 5 minutes, and up to 90% after 2 months.*

Leveraging decades of scientific research and following $10M+ invested in third-party clinical validation by leading institutions, we are introducing a new class of wearable technology that utilizes bioelectric impulses to target beneficial neural pathways without chemicals or surgery.

“My journey to healing brought me to Nurosym, which I discovered through my Functional Medicine Doctor, Daniel Auer optimalbrain. Over the past few months, while incorporating other tools to support my nervous system, I’ve noticed significant improvements in my overall health. My mind feels clearer, and I’m less overwhelmed by triggers and anxiety. I’ve developed greater resilience and can better manage my responses to daily challenges.
I’ve also observed increased focus, reduced inflammation, and fewer anxious thoughts. These changes have made a remarkable difference in my day-to-day life.”

Daily protocol to optimize Nurosym for your individual needs

When used correctly, Nurosym may boost parasympathetic activity by over 61% in just five minutes* and deliver 2-4x greater parasympathetic activation than breathwork or meditation. Monitor your HRV with a smart device like Apple watch to track progress.

Morning Activation 30 minutes

Use Nurosym as soon as you wake up to kickstart your parasympathetic system and fortify resilience against daily stressors. This session helps set a calm, balanced tone for the day ahead. Especially useful for those managing symptoms like brain fog and tiredness.

Midday/Evening Wind-down 30 minutes, optional
