ZenoWell vagus nerve stimulator device is a wearable and non-invasive vagus nerve device. Enhance sleep, reduce stress and tension, and alleviate fatigue and body pain by stimulating the auricular branch of vagus nerve with scientifically supported parameters.

The vagus nerve is a critical part of the parasympathetic nervous system. Its activity highly affects involuntary body functions, central nervous activity, and chronic inflammation responses.

No. However, we recommend that you consult with your doctor if you’re unsure whether ZenoWell vagus nerve stimulator device is right for you.

Moisten the earpiece with gel or water, put the earpiece in your left ear, select mode and intensity, close your eyes and enjoy the ear massage. You may experience some stinging or strong tingling at first, which will then transition to a soft vibration that acts like an ear massage.

Higher intensity doesn't mean better results. Individual sensitivity varies significantly, so the optimal level is personal.

Choose an intensity where you feel strong stimulation or a vibrating sensation in your ear, but without any pain or discomfort. If you experience pain, reduce the level immediately. The right intensity should feel noticeable and engaging, but always comfortable.

Our modes have different stimulation patterns. Sleep and Relief modes provide continuous stimulation, while Relax and Medit modes use intermittent stimulation (4 seconds on, 4 seconds off).

Stimulation intensity can vary due to factors affecting conductivity between the electrode and your skin - including gel amount, ear cleanliness, and earpiece-to-skin contact. This is normal. Simply adjust the intensity level to what feels right for you: strong but not painful.

Each mode uses different stimulation parameters, creating distinct sensations:

Sleep Mode: Continuous stimulation with varying rhythms. The intensity alternates between stronger and gentler waves, creating a dynamic but soothing pattern.

Relax Mode: Intermittent stimulation with a moderate intensity. You'll feel 4 seconds of stimulation followed by 4 seconds of pause, designed to sync with calm breathing patterns (exhale during stimulation, inhale during pause).

Medit Mode: Intermittent stimulation with stronger intensity. Similar to Relax mode, you'll experience 4 seconds on and 4 seconds off, but with more pronounced stimulation to support focused meditation and mental clarity. Recommand to sync with calm breathing patterns (exhale during stimulation, inhale during pause).

Relief Mode (Luna only): Continuous acupuncture-like stimulation. You'll feel brief, needle-like sensations approximately once per second in the ear, mimicking traditional acupuncture points.

No, ZenoWell vagus nerve stimulator device works independently of medication.

It is a non-pharmaceutical wellness device designed to support your body’s own self-regulation system. That said, if you are currently on medication, you can continue using ZenoWell vagus nerve stimulator device alongside it—but we recommend consulting your doctor for any changes to your treatment plan.

More than 65% of clinical studies chose left ear. Clinical studies have shown that using vagus nerve stimulation in the left ear can improve sleep, anxiety, and reduce fatigue and body pain effectively.

Yes. Extra accessories can be ordered from our online store.

Luna Plus includes four built-in modes that can be started directly from the device: Sleep, Relax, Relief, and Medit. After connecting to the app, you can also access Focus and Digest, along with guided audio, Face Scan, session history, and other connected features.

No. Face Scan is optional. You can complete the scan to view estimated HR, HRV, and signal quality before the session, or tap Skip to continue directly.

Start at a low intensity and increase it gradually using the + button. Choose a level that feels noticeable but comfortable. A gentle tingling or pulsing sensation is normal. Reduce the intensity if it feels sharp, painful, or uncomfortable.

1. SLEEP mode: Use before bed or naps to help your body and mind wind down.
2. RELAX mode: Use for moments of stress, tension, or overwhelm—anytime you need to reset and calm down.
3. MEDIT mode: Designed to support mindfulness and gently boost your energy. For best results, pair your breathing with the stimulation: Exhale slowly when you feel the stimulation, and inhale gently during the pause.

ZenoWell Vita is ideal for people dealing with:

• Sleep issues (difficulty falling or staying asleep and poor sleep quality)
• Chronic stress, anxiety, or low mood
• Fatigue or physical discomfort from overwork or post-covid symptoms

Some users report noticeable improvements within the first week.

However, for more stable and long-lasting effects—such as improved sleep quality, reduced anxiety, or allieviate fatigue and pain—regular daily use for 2 to 4 weeks is recommended. Effects tend to build over time with consistent use.

• RELIEF mode: A soothing mode designed to ease head pressure and promote a sense of clarity and lightness. Perfect for days when your head feels heavy or overworked.
• SLEEP mode: Use before bed or naps to help your body and mind wind down.
• RELAX mode: Use for moments of stress, tension, or overwhelm—anytime you need to reset and calm down.
• MEDIT mode: Designed to support mindfulness and gently boost your energy. For best results, pair your breathing with the stimulation: Exhale slowly when you feel the stimulation, and inhale gently during the pause.

• The main difference between Vita and Luna lies in their functionality and design. Luna is specifically tailored to address various pain scenarios and chronic inflammation, such as migraines, cluster headaches, period pain, chronic body pain, and joint pain.
• Luna offers 2x longer battery life than Vita. Luna can support more than 20 sessions.
• Luna features a more portable design and boasts a completely distinct, eye-catching aesthetic.
• While Luna features compact UI elements and smaller text, Vita provides a more spacious interface with larger fonts.

ZenoWell Luna is ideal for people dealing with:

• Migrane, cluster headache, period related headache, or any other primary headaches
• Sleep issues (difficulty falling or staying asleep and poor sleep quality)
• Chronic stress, anxiety, or low mood
• Fatigue or physical discomfort from chronic inflammation, overwork, or post-covid symptoms

For headache relief, many users experience noticeable improvement within 20 minutes of using Luna's Relief mode or 2 hours after using Luna. For sleep improvement, some users report benefits within the first week.

However, for more stable and long-lasting results—such as better sleep quality, reduced anxiety, or relief from fatigue and discomfort—we recommend using the device daily for 2 to 4 weeks. To prevent or reduce the number of headache days, consistent use twice daily for 4 weeks is advised. The effects are cumulative and tend to build over time with regular use.

More than 65% of clinical studies have focused on the left ear. Research has demonstrated that left-ear vagus nerve stimulation (taVNS) can effectively improve sleep quality, reduce anxiety, and alleviate fatigue and body pain.

Yes, right earpieces are available for purchase on our website. Please note that the default configuration for most taVNS devices includes a left earpiece, as this is the standard based on clinical research.

No, the Vita and Luna devices can only pair with one earpiece at a time. If you wish to use the right earpiece, please alternate between the left and right earpieces rather than using them concurrently.

The earpiece comes in one standard size, but we include a silicone ear sleeve to accommodate individuals with larger ears. This adjustable design ensures a proper fit for approximately 90% of users.

No, the silicone ear tip does not conduct electricity. Removing the ear tip does not affect the electrode function. The ear tip is designed solely to improve fit for larger ears. As long as the electrodes are positioned correctly, the ZenoWell vagus nerve stimulator functions effectively with or without the ear tip.

Each box can be used approximately 300 times. If used twice a day, it can last for about 5 months.

Please keep the gel out of reach of infants to prevent accidental ingestion. If you experience any discomfort after use, stop using it immediately and consult a medical professional. Do not use the gel on broken, infected, swollen, or allergic skin.

No, the gel is odorless.

The primary ingredients include water, glycerin, propylene glycol, and other non-toxic, specially formulated components designed to enhance stimulation comfort.

Apply a thin, even layer of gel to the surface of the electrode of the earpiece before placing the electrode on the ear for stimulation.

The shelf life of the unopened gel is 3 years.
