The first at-home taVNS device built on the JAMA 2024 dosing protocol.

Lull is a non-invasive, FDA-listed Class II transcutaneous auricular vagus nerve stimulator. The 20-minute nightly dosing protocol was published in JAMA Internal Medicine, 2024, and Lull was engineered around it from the ground up.

  • FDA-listed Class II medical device, manufactured in the US
  • Built on the published JAMA 2024 protocol — 20 minutes nightly, clipped to the cymba conchae
  • Developed alongside clinical sleep researchers and autonomic-nervous-system specialists
  • Backed by a 60-night home trial — try it for two cycles, send it back if it doesn't work
Sarah

"Honestly, I read the actual JAMA paper before buying. Once I saw the dosing protocol was real published science, I trusted it more than anything else I'd tried."

To rewire your nervous system — without adding another thing to manage.

Most nervous-system tools work above the neck. Lull works below it, directly on the vagal pathway that controls your body's parasympathetic switch. There's nothing to subscribe to, refill, or remember.

  • Stimulates the auricular branch of the vagus nerve — the body's primary off-switch
  • Shifts the nervous system from sympathetic dominance ("on") to parasympathetic activation ("off")
  • No subscriptions, no refills, no monthly cost — buy once, use nightly
  • Twenty minutes per night is the entire commitment
Maya

"I was juggling supplements, two apps, a Whoop, and twice-monthly therapy. I'm down to this and therapy now. My whole nightly routine takes five minutes."

To build emotional resilience between therapy sessions.

Talk therapy works above the neck. The body still holds what the mind has processed. Lull is the somatic complement — the nightly down-regulation that gives therapy something to build on.

  • Lowers physiological stress baseline measurably within 2–4 weeks
  • Increases vagal tone — the body's underlying capacity for emotional regulation
  • Reduces hyperarousal in the hours between sessions
  • Used by trauma-informed therapists as a between-session intervention
Caroline

"My therapist literally asked what I'd been doing differently. Suddenly the work we'd been doing for years started actually landing in my body."

For deep, uninterrupted sleep you can't earn back.

Most sleep tools sedate you into sleep. Lull does something different — it shifts your nervous system out of the "on" state so your body can sleep on its own. The kind of sleep you wake up restored from, not foggy.

  • Promotes deeper REM and slow-wave sleep
  • Reduces the 2am and 4am wake-ups that anxiety drives
  • Lowers nighttime cortisol measurably
  • No grogginess in the morning — non-sedative mechanism

"I genuinely can't remember the last time I woke up at 2am. That hasn't happened to me since my first baby was born."

To counter chronic tiredness, burnout, and post-viral fatigue.

A body that's been on guard for years forgets how to recover. Lull retrains the parasympathetic response that recovery depends on — the system responsible for restoration, digestion, and repair.

  • Restores autonomic balance — the foundation of energy and clarity
  • Supports HPA axis recovery after prolonged stress
  • Used in post-COVID fatigue and long-COVID protocols
  • Daytime energy and mental clarity improve as nervous-system tone restores

"After long covid I had a wall hit me at 2pm every single day. About six weeks in, that wall just stopped showing up. I have afternoons again."

To support gut-brain axis function and digestion.

The vagus nerve is the highway between your brain and your gut. When vagal tone drops, digestion suffers. Lull restores the signal directly — and the gut-brain axis follows.

  • Improves vagal tone — the primary regulator of gut motility
  • Supports women with IBS, SIBO, and functional gut conditions
  • Reduces low-grade inflammation along the gut-brain axis
  • May relieve bloating, abdominal tension, and post-meal discomfort
Lena

"My IBS controlled my life for years. I'd cancel plans, eat plain rice for days. I have normal eating days now and I can barely believe it."

To stabilize mood and lift low-grade depression.

When the parasympathetic system is suppressed, mood follows. Lull works on the same vagal-mood-inflammation pathway that anti-depressants and SSRIs target — without the side-effect profile.

  • Targets the vagal-mood-inflammation pathway
  • Used as an adjunct to SSRIs and SNRIs under medical guidance
  • Reduces emotional volatility and afternoon mood crashes
  • Restores baseline mood between therapy and medication adjustments
Camille

"I'm still on my SSRI and I'm not coming off it. But the floor under my mood has stopped giving way. Whatever Lull does, it does cleanly."

To improve HRV and cardiovascular tone.

Heart rate variability is the single best biomarker for nervous-system health. Lull improves HRV directly — and resting heart rate, cardiovascular recovery, and athletic performance follow.

  • Increases parasympathetic HRV (RMSSD) within weeks
  • Lowers resting heart rate
  • Supports cardiovascular recovery after stress and exertion
  • Used in athletic recovery protocols by performance coaches
Anna

"My RMSSD went from the high 30s to the mid 60s in eight weeks. I track on Whoop. I've never seen a single thing move it that much — not even cold plunge."

To sharpen cognitive function as you age.

The vagus nerve influences memory, attention, and executive function via the brain's locus coeruleus pathway. Lull stimulates that pathway directly — without stimulants, supplements, or side effects.

  • Supports working memory and sustained focus
  • Promotes neuroplasticity via norepinephrine release
  • Reduces markers of age-related cognitive decline
  • Improves attention regulation and mental clarity
Rachel

"I work in tax law and I'm 53. My afternoon brain fog completely lifted after about a month. Nothing else in my routine changed."

When talk therapy alone isn't reaching the body layer.

Therapy processes what's in the mind. The body still holds the rest. Lull is the body-up tool that meets therapy where it ends — the somatic complement clinicians have been looking for.

  • Designed as a somatic complement to talk and trauma therapy
  • Used by therapists between sessions as a regulation tool
  • Addresses the body's stored stress response directly
  • Recommended in trauma-informed care protocols
Dr. Helena

"I'm a trauma-informed therapist. I tried it on myself before recommending it to any client. It accomplishes what we spend years trying to teach the body to do."

As a non-pharmaceutical alternative to adding more meds.

For women who've already reached the edge of their medication tolerance, Lull offers a path that doesn't require another prescription, another side-effect profile, or another monthly refill.

  • No drugs, no side effects, no dependence
  • Safe alongside SSRIs, SNRIs, and benzos — no known interactions
  • May reduce reliance on PRN anxiety medication over time (under medical guidance)
  • 60-night home trial — try it for two cycles before deciding

"I've been on Klonopin for nine years. I haven't reached for it during the day in almost two months. After nine years, that means something."
