Introducing Noxtee: the nighttime formula engineered to reset the brainstem volume knob stuck in post-infection overdrive—so you can fall asleep without listening to the static, wake once instead of three times, and stop the 3am panic loop.
Sleep through it or your money back — 90 days
You are not imagining it. You did not fail to finish your antibiotics.
The screaming in your head is not happening inside your ear canal. It is generated at a pea-sized nerve bundle at the base of your skull—your brainstem—and it has been locked on high alert since your infection hit.
Every sound your ear picks up travels through your auditory nerve to a central junction: the Dorsal Cochlear Nucleus (DCN).
This bundle acts as the master volume knob for your hearing. Quiet room, it turns the gain up so you can hear a whisper. Loud truck goes past, it turns the gain down to protect your brain.
It has been quietly setting your internal volume since the day you were born.
When you had an ear infection, sinus inflammation, or fluid buildup, your middle ear swelled up. Outside sound became muffled—it felt like you were underwater.
The Dorsal Cochlear Nucleus noticed the weakened incoming signal and did what any sound system does when the input drops: it cranked its internal gain knob up to 100%.
Turn a radio amplifier up to 100 with no clear station tuned in, and the speakers emit a loud, screeching static hiss.
When your antibiotics killed the bacteria and the swelling went down, your ear hardware went back to normal. Your doctor looked inside with an otoscope, saw a clean eardrum, and declared you "cured."
Standard hearing tests stop at 8,000 Hertz. Post-infection acoustic gaps sit just above 8,000 Hertz—off the chart entirely. So your test comes back "100% normal," your file gets closed, but your central volume knob remains locked at 100 in high-gain overdrive. That screeching static is the sound seven specialists couldn't find in your ear canal.
It runs all day long. Three daytime covers hide it while you are awake: environmental background noise, your conscious focus, and your brain's waking filter that discards meaningless static.
At eleven o'clock the house goes quiet, and you lose the first cover. That is why you run a high-speed fan in January.
By three in the morning, sleep pressure drops, your body's stress hormone begins its natural morning climb, and you wake up.
The second you lie there in the dark covering one ear, checking the pitch, and rating it against last night, you send a direct danger signal to your alert brain: "This sound matters." And your brain responds by turning up the volume on things that matter. The 3 AM checking loop is the fuel feeding the high-gain engine.
The noise doesn't get louder at 3:00 AM. You get more awake—and your stuck volume knob takes over the room.
Noxtee combines glycine at 3,000mg (3 full grams)—the clinical research dose that dumps core heat through your hands and feet to trigger immediate body cooling. It is the one ingredient nobody selling you a generic tinnitus pill or ear drop has ever put in front of you at a real dose.
Standardized saffron extract, L-theanine, and magnesium bisglycinate—the high-absorption form that crosses into the central system, not the cheap oxide sitting in your drawer that did nothing for your ears. Timed to work in sequence to shut off the 3 AM brainstem wind-up. Two capsules, once a night at 9:00 PM.
And you don't need to sit through another 4-minute otoscope appointment, spend another $4,000 on sound-masking hearing aids you'll wear twice, or swallow another "ringing relief" supplement with 14 micro-dosed ingredients that do nothing for your brainstem… to get your quiet nights back.
Because Noxtee targets both halves of what keeps post-infection sufferers trapped—the volume turned up at the brainstem DCN AND the 3 AM checking loop that feeds it… so you can finally:
Clinical Audiologist • 18 years in tinnitus management
"Every week I see patients who recently recovered from an ear infection or sinus inflammation with a clean otoscope exam and ringing that is violently real. The standard audiogram looks at the ear canal—but the signal that becomes the screaming is turned up at the master volume knob in the brainstem. That is not a place a standard ear scope can see. Noxtee starts at the brainstem. That is why it works when drops fail."
Board-Certified Neurologist • Central Auditory Pathway Focus
"Post-viral tinnitus is rarely an ear hardware problem. When fluid muffles hearing, the Dorsal Cochlear Nucleus in the brainstem turns its central gain to maximum. Even after the infection clears, that neural volume slider stays locked in overdrive. The location of persistent ringing is neurological, not aural."

"Jaw clenching after an ear infection is not a separate issue. Clenching and ringing are two outputs of the exact same junction in the brainstem where jaw, neck, and auditory nerves meet. A night guard protects enamel, but it cannot reach the central Dorsal Cochlear Nucleus. That is why guards and drops fail together."

Everyone's timeline varies. But across 3,000+ post-infection cases, a clear pattern emerges.
The 3,000mg glycine dumps core heat through your hands and feet—the physical signal your nervous system uses to initiate sleep. Most people notice the gap between lying down and falling asleep getting significantly shorter. Not total silence yet. Just less time lying in the dark testing the noise.
You wake once at night instead of three times. And the first time you stir at 3:00 AM, hear a faint murmur, and roll over back to sleep without covering your ear to rate it—that is the week the breakthrough happens. You won't notice it at 3 AM. You'll notice it at breakfast when you realize you didn't check the pitch the second your eyes opened.
Effortless sleep onset every night. You finish a book without losing concentration. You stay at the dinner table. The static is still there if you actively hunt for it in a soundproof room—but it isn't the loudest thing in your head anymore. Sleep is.
You stop checking the pitch altogether. And when you stop checking it, you stop feeding the high-gain engine—which is the core truth seven ear specialists never explained to you. That is why 87% of post-infection users reorder.

"My ear infection cleared in August, but the high-pitched hiss got twice as loud. My ENT told me my audiogram was perfect and to 'learn to live with it.' I spent $1,400 on ear drops, nasal sprays, and Amazon pills that did zero. Week three on Noxtee, I woke at 3 AM, heard a faint whisper, and went right back to sleep without checking if it changed pitch. I hadn't slept like that since before I got sick."
Glycine — 3,000mg. Three full grams. Not 300 milligrams—three thousand. This is the exact clinical dose used in sleep studies, and it is the single ingredient nobody selling you ear drops or "tinnitus vitamins" has ever given you at a real dose. It works by dumping core body heat out through your hands and feet—the precise biological signal your brain requires to drop into deep sleep. It is Step 3, and it is why our bottle is the size it is.
L-Theanine — 200mg. Step 1. It dampens the fight-or-flight alarm response, so when you do hear the static at night, your entire central nervous system doesn't flare up behind it. You hear it, and your body stays completely calm.
Standardized Saffron Extract — 28mg. Step 2. Not raw saffron powder—a pure standardized clinical extract. It closes the gap between lying awake checking your ears and falling asleep.
Magnesium Bisglycinate — 200mg. Step 4, and the foundation underneath the entire formula. If you've taken cheap magnesium oxide before and felt zero change, it's because oxide passes right through you. Bisglycinate is chelated to glycine, allowing it to cross directly into your system to hold the Dorsal Cochlear Nucleus calm through the night—so a 3:00 AM stir doesn't spiral into an hour of panic-checking.
Two capsules. 9:00 PM at night. With water. No morning pills. No ear drops. Every ingredient is dosed at full research strength in a strict 4-step sequence.
Everything your ear picks up arrives first at a pea-sized nerve bundle at the base of your skull—the Dorsal Cochlear Nucleus (DCN). Its job is deciding how loud sounds need to be amplified.
When you had an ear infection or fluid buildup, your middle ear muffles outside sound. The DCN noticed the weak signal and did what a volume knob does: it turned itself up to 100%.
Standard hearing tests stop at 8,000 Hertz. Infection-triggered loss sits just above 8,000 Hertz. It never shows on the chart, your doctor says "you're normal," but your central volume knob remains locked at 100 in high-gain overdrive.
At night, background noise disappears. When you wake at 3 AM and lie there checking the pitch, you tell your brain the static matters—and your brain turns up what matters. The checking loop is the engine feeding the sound.
Noxtee works in 2 phases:
Phase 1 (Nights 1–14): L-theanine and saffron quiet the alarm and close the sleep gap, while 3,000mg glycine triggers core body cooling. You fall asleep faster without checking your ears.
Phase 2 (Week 2 onwards): Magnesium bisglycinate holds the central gain steady. You wake at 3 AM, hear a faint tone, and fall right back to sleep without rating it. That is the exact night the engine stops being fed.
Most remedies target the ear canal. Your ear canal is clean. The brainstem is where the volume was turned up. That is the difference.

I don't write reviews, but this saved my sanity. Ear infection in August, antibiotics cleared the pain, but the ringing came back 3x louder. ENT looked in my ear and said 'everything looks clean, learn to live with it.' Meanwhile I was running two fans in January just to lie down. Three weeks on Noxtee and I woke up on a Saturday morning, made coffee, and realized I hadn't checked my ear volume once. The static dropped into the background. First thing that actually touched the noise in 18 months.

THE FAN IS OFF. That's the review. Had a severe sinus infection in 2021 that left me with an electrical hiss. Slept with no background noise for the first time in 5 years. 🙌

Tried Lipo-Flavonoid, Quietum Plus, ear drops, steam inhalers, and a $3,000 sound masking device after a middle ear infection. Zero results. Noxtee is the first thing that explained WHY it happens (the volume knob in the brainstem) instead of trying to squirt drops in a clean ear canal. 5 weeks in and I sleep 7 hours straight.
Verified Customer
The 3 AM checking stopped. Just stopped. I'd been covering my right ear every night at 3 AM to rate the pitch against the night before. Week three on Noxtee, I woke up, heard a faint hum, and went right back to sleep. Stopped feeding the loop. 🙏

Ringing for 4 years after a severe flu and fluid buildup. Audiogram was 'perfect' according to two ENTs while my head was screaming at 80 decibels. Noxtee worked within 20 days. Head is quiet, focus is back, reading books again. Ordered 3 more bottles.
Verified Customer
68 years old. Ringing started after a sinus infection in 2019. I tried everything on Amazon. Eleven bottles in my nightstand drawer and $1,400 wasted. My daughter found Noxtee and I almost didn't buy it because I was tired of being burned. So glad I did. I fell asleep on night 10 without noticing I fell asleep. That might sound small, but if you've lived with post-infection noise, you know it's everything.

My ENT said my ear canal was pristine. Meanwhile I couldn't sit through a meeting at work without my head buzzing. Three weeks on Noxtee and my nights held. First formula that matched what I was actually experiencing in my brainstem instead of staring at my eardrum.
It's a 2-phase nightly capsule routine designed to address the relay station behind your ear — the dorsal cochlear nucleus — the part of your auditory pathway the audiogram doesn't measure.
Phase 1: L-theanine and saffron extract calm the cortisol-axis stress that's been wearing the inhibitory brakes down all day.
Phase 2: 3,000mg glycine and magnesium bisglycinate refill the two natural brakes — magnesium and glycine — at research-strength doses.
Most "tinnitus" formulas (Lipo-Flavonoid, Quietum Plus, Tinnitus 911) target the cochlea or throw a kitchen-sink blend at the ear. The cochlea is the speaker. The relay is the amplifier. Most "calm" formulas only do trace amounts of step 2 ingredients — 100mg of glycine, 50mg of magnesium oxide. Noxtee does both phases, at the doses published research uses, in the right order. That's why patients who'd already tried everything saw something different on Noxtee.
90 nights to feel the night hold. If it doesn't, keep what's left — every cent back, no return shipping required.
Probably more than your GP has told you.
Here's the chain nobody connects. Every night the relay over-fires, your sympathetic nervous system stays in fight-or-flight while you're trying to sleep. Cortisol stays elevated. Your blood pressure does not dip the way it's supposed to during sleep — it stays elevated for eight straight hours, every night, for years. That is the load behind the cardiac events that show up in women in their 50s and 60s — events that should be happening twenty years later.
Sofi et al. 2014 meta-analysis: chronic insomnia is associated with roughly a 45% increase in cardiovascular mortality. The 2026 review in Nature Reviews Neurology confirmed the brake-failure mechanism behind it.
Noxtee does reload the two brakes that quiet the relay so your nervous system can downshift at night the way it's supposed to. The cardiovascular risk pathway runs through chronic broken sleep. That's where Noxtee starts.
If you don't feel the night hold within 90 nights, keep what's left and we refund every cent.
Yes. In fact, it's specifically for you.
The audiogram tests the cochlea — the speaker. The signal that becomes the ringing fires one stop upstream, at the dorsal cochlear nucleus — the amplifier. The audiogram cannot reach that relay. So your test was honest. It just wasn't looking where the ringing actually fires.
A "normal audiogram" is not a clean bill of health. It is the result that closed your ENT's file the moment the cochlea checked out — while the relay above it kept firing every night. The relay was never on the test.
If your audiogram came back normal, your ENT told you to "learn to live with it," and your nights are still wrecked — Noxtee was built specifically for you. 90 nights to feel the difference. Worsening-protected refund.
Fair question. You've probably already spent $300 to $1,500 on Lipo-Flavonoid bottles, Tinnitus 911, magnesium oxide pills, melatonin gummies, lavender oil, white noise machines, and a night guard. None of it touched what's actually firing.
Noxtee is the only nightly routine on the market dosed for the relay junction upstream of the cochlea. The doses aren't marketing — they're what the research uses:
3,000mg glycine. The Yamadera 2007 dose.
200mg magnesium bisglycinate. The bioavailable form that crosses the blood-brain barrier.
200mg L-theanine. The trial-grade dose.
28mg saffron extract. The mood and sleep-quality research dose.
90 nights to feel the night hold. Worsening-protected refund — if your nights feel worse, not better, contact support, keep what's left, every cent back. No return shipping. No chat queue. No questions.
The only risk is staying exactly where you are.
Because the relay junction isn't on their test, and the formulation isn't a prescription.
ENTs are trained to read cochleas. The dorsal cochlear nucleus sits in the brainstem — outside their imaging, outside their certification, outside the audiogram. When the test comes back clean, the case closes. That's not malpractice. That's the limit of the tool.
The 2026 Nature Reviews Neurology review on glycinergic and NMDA modulation at the dorsal cochlear nucleus is recent. Yamadera 2007 sat shelved for over fifteen years before the field caught up. The doses Noxtee uses are research-grade, not prescription-grade — your ENT is not licensed to prescribe a nightly routine. They are licensed to test the cochlea and refer.
The reason most patients hear about this from each other before they hear it from a specialist is that the gap between published neurology and ENT practice is roughly fifteen years. Noxtee is what closes that gap.
We get this question more than almost any other.
Lipo-Flavonoid is bioflavonoid-based. It targets vascular flow at the cochlea. It's been on the shelf since the 1960s and it does not touch the relay junction at the dorsal cochlear nucleus. If your audiogram came back normal, Lipo-Flavonoid was solving the wrong organ.
Quietum Plus is a proprietary blend. The label hides individual doses behind the "proprietary blend" label so you cannot see how much of anything is in it. You're paying for a marketing label, not a verifiable research dose. Real biology requires real doses you can read on the supplement panel.
Tinnitus 911 sells a vitamin and herb blend marketed primarily through aggressive paid placements. None of its ingredients are dosed for the relay junction. It relies heavily on bioflavonoids and surface-level vitamins — nothing that reaches the inhibitory brakes at the dorsal cochlear nucleus.
Noxtee uses 4 ingredients, all individually disclosed at research-grade doses, all targeting the actual junction where the ringing fires. No proprietary blend. No bioflavonoid theater. Real doses, the order they need to be taken, the form that reaches the brain.
90 nights to compare it side-by-side. If it doesn't outperform whatever you're taking now, keep what's left and we refund every cent.
Yes — and this is the single most common medication stack we see among Noxtee buyers.
Noxtee contains no synthetic compounds and no prescription-active ingredients. Just L-theanine, saffron extract, glycine, and magnesium bisglycinate. All four are widely tolerated alongside:
Statins (atorvastatin, rosuvastatin, simvastatin)
BP medications (lisinopril, losartan, amlodipine, metoprolol)
Blood thinners (apixaban, warfarin, clopidogrel)
SSRIs and anti-anxiety medications
Prescription sleep aids (zolpidem, eszopiclone)
Thyroid medications (separate by 4 hours)
Magnesium bisglycinate at 200mg is well below the threshold associated with any clinical interaction. Glycine at 3,000mg is the dose used in the Yamadera trial — published, peer-reviewed, well-tolerated.
If you are on a prescription, run the ingredient list past your prescribing doctor before you start. Email contact@noxtee.com and we'll send the full dose breakdown — print it, bring it to the appointment.
Yes — and it's the only dose with measurable sleep-quality data behind it.
Yamadera et al. 2007 measured sleep-quality changes at exactly 3 grams glycine, 30 to 60 minutes before bed. Lower doses (500mg, 1g) did not produce the same effect on subjective sleep quality or on polysomnographic measurements. The biology requires the dose.
Glycine itself is one of the most abundant inhibitory neurotransmitters in your nervous system. Your body produces it. You consume it from protein. A cup of bone broth contains roughly 3 to 4 grams. The dose is well within the natural range — it's just concentrated and timed for the window when your relay needs it most.
Most "calm" or "sleep" gummies use 100 to 500mg of glycine — a marketing gesture, not a therapeutic dose. Noxtee uses the trial dose. 3 grams. Every night. That's why the brake actually reloads.
That's the most common starting point we see. Most people who find Noxtee have already done:
The magnesium oxide. The Lipo-Flavonoid (sometimes for years). The Quietum Plus or Tinnitus 911. The melatonin gummies. The valerian root. The lavender essential oil on the pillow. The white noise app, then the fan, then the second white noise app to mask the first. The ashwagandha. The L-theanine on its own. The night guard. The four-figure ENT bills. The "have you tried meditation" from a well-meaning friend.
None of it worked because none of it reached the relay junction.
The cochlea was the wrong target. The ear muscle was the wrong target. The melatonin half-life was the wrong target. The relay junction at the dorsal cochlear nucleus — the place every signal from your ear, jaw, and neck has to pass through on its way to your brain — was the missing target every single one of those products skipped.
Noxtee starts where everything else stopped. 90 nights at the trial dose. Worsening-protected refund.
The wind-down change comes first. Most people notice the bedtime bracing — the 9:30 PM "what is the room going to sound like" anticipation — easing up by night 5 or 6.
The 3 AM wakeup pattern usually starts breaking around week 3. When you do wake up, the night doesn't restart from zero — you fall back asleep faster.
Mornings start feeling less like a verdict by week 5 or 6. The "how loud is it today" first thought fades.
The full pattern shift takes 90 nights — which is why the trial window is 90 nights, not 30. Some bodies respond faster, some slower. Magnesium and glycine reload over weeks, not hours. The relay has been running on empty for years. Reloading both brakes consistently takes the time it takes.
The 90-night worsening-protected guarantee covers you either way.
Every nervous system in human biology runs the dorsal cochlear nucleus on the same two inhibitory mechanisms — magnesium ion blockade at the NMDA receptor, and glycine inhibition at the receptor downstream. That's not a regional difference. Not a Hashimoto's-vs-non thing. Not a "my body is unique" thing. That's basic neurology, in every textbook.
Whether your gauntlet history has 2 specialists or 7 in it, whether you've worn a night guard for 6 months or 16 years, whether you have hearing aids or not — the relay still runs on those two brakes. Noxtee refills them.
If your nights feel worse, not better, after 90 nights — contact support, keep what's left, every cent back.
Yes. And this is one of the reasons Noxtee works for people who saw their dentist before they saw an audiologist.
The dorsal cochlear nucleus is where signals from your jaw, your neck, AND your auditory nerve all converge. Three nerves, one junction. Clenching feeds the same junction that's already over-firing from the auditory side.
A night guard protects your teeth from the grinding. It does not protect the relay from the signal. The signal still arrives. The brakes still get burned through. The 3 AM wakeup still happens.
Keep wearing the guard for your teeth. Take Noxtee for the relay the guard doesn't reach.
Noxtee is non-habit-forming. Contains no melatonin, no GABA agonists, no benzodiazepines, no kava, and no sedating antihistamines — none of the compounds that create dependency or downregulation.
Glycine, magnesium, L-theanine, and saffron are well-tolerated. Glycine in particular is one of your nervous system's own inhibitory neurotransmitters — your body makes it. Magnesium bisglycinate at 200mg is well below any threshold associated with side effects in published research. Most people experience no side effects at all.
No. The goal is to restore the routine, not create a dependency.
Many people take Noxtee nightly for 90 to 180 nights, find their pattern stabilizes, then either reduce to a few nights a week as needed or stop entirely. Some keep taking it nightly because the wind-down support is something they want every night.
Your body still produces glycine on its own. You still process magnesium from food. Noxtee is supporting those systems at the relay junction during the years they're depleted. Once the pattern shifts, your body keeps making and using both — the same way it always has.
Stop anytime. No tapering protocol. No withdrawal. No rebound.
No. The dorsal cochlear nucleus does not have an expiration date.
Your nervous system still uses the same two inhibitory mechanisms it used the night this started — whether that was 2014 or 1998. Magnesium ion blockade. Glycine inhibition. Both still work at the receptor level whether you're 35 or 75. The brakes can be refilled at year 1 or year 21.
Some of the strongest pattern shifts we see come from people who'd been "managing this" for 10, 15, 20 years and had stopped expecting anything to change. The biology doesn't care how long it's been. It cares whether the inputs are there.
If 90 nights at the trial dose don't shift your pattern — keep what's left, every cent back, no questions.
We know.
That might be the most honest sentence on this entire page. You've been let down by 4 specialists, every supplement on the shelf, two different night guards, and the audiogram that came back "normal" while your nights kept falling apart. Protecting yourself from another disappointment feels safer than trying.
We can't promise you a miracle. We can promise you this:
The mechanism is real. The doses are at research-grade strength. Yamadera 2007 measured the glycine effect at 3 grams. The 2026 Nature Reviews Neurology review confirmed the brake-failure pathway. The biology is universal — every nervous system runs on these two brakes.
90 nights to feel the night hold. Worsening-protected refund — if your nights feel worse, not better, keep what's left and we refund every cent. No return shipping required. No chat queue. No questions.
The only real risk is staying exactly where you are — for another year, another decade, another 3 AM wakeup that starts the night over.
The brakes can still be refilled. The relay can still quiet down. The version of you who fell asleep without thinking about it is closer than you think.
