SCIENTIFIC EVIDENCE

A New Frontier in Accessible Healthcare

Built on decades of scientific research and $10M in evidence-based studies so far, Nurosym is leading a new class of wearable technology that uses bioelectric signals to target neural circuits, enhancing critical body functions without chemical or surgical intervention. Our purpose: Develop accessible, evidence-based noninvasive neuromodulation to improve our collective health.

Fine-tuning Vagus Nerve Health With AVNT™

The Vagus Nerve acts as the body's communication highway, linking the brain to vital organs and controlling essential functions like heart rate, digestion, and inflammation response.

Our in-house team of health professionals, scientists, and researchers worked with leading third-party institutions to rigorously study the effects of Vagus Nerve modulation through our proprietary AVNT™ method.

By modulating its activity through precise signal delivery and targeting the right nerve (on-target effect) but no other nerves (off-target effect), Nurosym can optimize this critical pathway, ensuring a seamless brain-body communication to provide wide-ranging benefits.


Our major research milestones:

  • Reviewed 10,000+ publications to engineer Nurosym
  • First prototype and extensive safety testing
  • Randomized controlled studies with leading institutions
  • First CE-marked Auricular Vagal Neuromodulation therapy (AVNT™) system
  • Over 3 million reported positive user sessions
