Your body’s secret to a happier gut
Over a century of vagus nerve research, now working for your gut.
See how Nevia® activates your body
Nevia® uses gentle bioelectronic stimulation through the vagus nerve to restore the brain–gut connection — reducing inflammation, easing stress, and supporting natural healing.
What is the Vagus Nerve?
The Vagus nerve is the longest nerve in your body, running from your brainstem all the way down to your gut. It controls digestion, inflammation, stress, and mood. When it works well, you feel it. When it doesn't, your gut lets you know.
Think of it as your body's built-in communication line between your brain and gut.
It runs your parasympathetic nervous system, the system responsible for calming your body down and keeping your digestion on track.
Numbers that matter
Independent researchers across multiple institutions measured these outcomes using protocols that mirror Nevia®’s approach.
Sleep Better
In a JAMA-published clinical trial, 7 in 10 participants reported dramatically improved sleep quality — and the benefits lasted months after treatment ended.
JAMA Network Open, 2024 — Randomized sham-controlled trial, n=72Lower Cortisol Under Stress
Vagus nerve stimulation cut the body’s cortisol spike in half during acute stress. Daily use over 3 months reduced baseline cortisol by 40%.
Physiological Reports, 2025 — Crossover study, p<0.05Gut Inflammation Drop by Half
In a sham-controlled trial, nearly two-thirds of IBD patients achieved a 50%+ reduction in their primary inflammation marker after 16 weeks.
Bioelectronic Medicine, 2023 — Sham-controlled clinical trial, n=17Clinically Significant Anxiety Reduction
Patients saw meaningful drops in standardized anxiety scores — with results comparable to medication, and fewer side effects.
Neuromodulation, 2025 · Journal of Affective Disorders, 2023Crohn’s Patients Achieved Remission
Half of Crohn’s patients reached clinical remission in 16 weeks. TNF, a key inflammatory driver, decreased 46%.
Bioelectronic Medicine, 2023 · World J Gastrointest Pathophysiol, 2022Serious Side Effects
Every published VNS study from 2021–2025 reports zero serious adverse events. Non-invasive. No pills. No surgery.
Multiple peer-reviewed RCTs — JAMA, JCI Insight, Bioelectronic MedicineResponse Rate for Depression
A meta-analysis of 10 RCTs found VNS delivers comparable results to antidepressants — with a lower side-effect profile. One trial reported 39% full remission.
Journal of Affective Disorders, 2023 — 10 RCTs, 222+ participantsPain & Digestion Relief for IBS
A sham-controlled trial showed significant improvements in bowel regularity, abdominal pain, anxiety, and quality of life.
JCI Insight, 2021 — Randomized sham-controlled trial, n=42Reduction in UC Inflammatory Markers
UC patients saw the most dramatic response — an 81% median drop in fecal calprotectin, with 1 in 3 reaching full clinical remission in 16 weeks.
Bioelectronic Medicine, 2023 — Sham-controlled clinical trial, n=17The vagus nerve is the body’s built-in anti-inflammatory highway. We’ve known this for years. What we haven’t had is a way to harness it for GI patients outside of a clinical setting. Nevia® changes that equation entirely. We’re not masking symptoms. We’re modulating the immune response at the neural level.
Peer-Reviewed Evidence
The science behind Nevia® isn’t new. It’s proven. Vagus nerve stimulation has been studied for over a century and used in clinical settings for decades. We took that research and built something you can use at home, on your own terms.
