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.
