Introducing Noxtee: the two-phase nightly relay formula engineered to support the brainstem's inhibitory "brakes" stuck in post-infection overdrive—so you can stop fearing every shift, protect your career, and get your concentration back.
Protect your workday or your money back — 90 days
You are not imagining it. You did not fail to finish your antibiotics, and you are not "just overreacting" to your office or workplace.
The screaming in your head isn't happening inside your ear canal. It is generated at a key auditory relay station at the base of your skull—your Dorsal Cochlear Nucleus (DCN)—and it has been stuck in hyper-reactive overdrive ever since your ear event.
Every sound your ear picks up travels through your auditory nerve to a central relay: the Dorsal Cochlear Nucleus (DCN).
This relay acts as the traffic controller for sound. It uses built-in inhibitory "brakes" to regulate incoming signals. It filters out background hums, keeps ordinary safe sounds calm, and pushes irrelevant noise into the background so your brain can focus on work.
When you had an ear infection, sinus inflammation, or fluid buildup, your middle ear swelled up. Outside sound became muffled.
Your auditory relay noticed the drop in input and compensated by turning its gain way up. But in doing so, the relay's inhibitory brakes weakened.
When your infection cleared, your doctor looked inside with an otoscope, saw a clean eardrum, and declared you "healed." Standard hearing tests stop at 8,000 Hertz, missing post-infection acoustic changes that sit higher up.
So your doctor says "everything looks normal," but your auditory relay remains hyper-reactive to ordinary input.
When you go to work, ordinary, safe workplace sounds—office chatter, headsets, machinery, classroom noise, ambient hums—hit an auditory relay that no longer has its inhibitory brakes engaged.
The result?
The problem isn't that everyday workplace sound suddenly became dangerous. The problem is that your auditory relay started treating everyday sound like danger.
This mechanism creates a brutal internal conflict:
"If I keep working while my ears feel vulnerable, I might cause permanent damage—but if I stop working, I lose my income, career, and independence."
You don't need to quit your job, hide in a soundproof room, or live in constant fear of everyday noise. You just need to support the inhibitory brakes that keep your auditory relay from over-reacting to normal life.
Noxtee doesn't try to squirt drops into a clean ear canal or hide the noise with cheap masking fans. It works through a targeted two-phase sequence designed around the central auditory pathway:
L-Theanine (200mg) + Standardized Saffron Extract (28mg): Eases the high-stress fight-or-flight arousal accumulated across a demanding, sound-auditing workday—so your nervous system stops holding your ears in a state of hyper-vigilance.
Glycine at 3,000mg (3 full grams): The clinical research dose of the primary inhibitory neurotransmitter your system uses to apply the "brakes" on over-firing neural relays.
Magnesium Bisglycinate (200mg): High-absorption chelated magnesium that crosses into the central nervous system to help prevent neural hyperexcitability and hold the relay steady.
You don't need to spend thousands on sound-masking hearing aids you're embarrassed to wear at work, suffer through useless ear drops, or quit the job you worked years to build.
Because Noxtee targets the root mechanism keeping post-infection sufferers trapped—the over-reactive signal at the brainstem DCN AND the daytime sound-auditing loop that feeds it… so you can finally:
Clinical Audiologist • 18 years in tinnitus & hyperacusis management
"Patients who experience tinnitus spikes after an ear infection often assume workplace noise is inflicting fresh acoustic damage. But in clean-otoscope cases, the issue is usually an over-reactive Dorsal Cochlear Nucleus in the brainstem. The ear canal is healthy, but the central relay has lost its inhibitory regulation. Addressing the relay mechanism is what allows patients to tolerate normal workplace sound again."
Board-Certified Neurologist • Central Auditory Pathway Focus
"When an infection temporarily alters auditory input, the brainstem relay turns up its gain. If the relay's inhibitory brakes remain unassisted, ordinary daily sound triggers exaggerated neural firing that the patient perceives as a 'reactive spike.' This is a central processing state, not ongoing outer-ear trauma."

The 3,000mg glycine works alongside L-theanine and magnesium bisglycinate to settle daytime stress arousal and promote body cooling. Sleep onset becomes noticeably smoother, giving your nervous system its first true recovery window since your infection hit.
You work a demanding shift with ambient noise and suddenly realize at 5:00 PM: you didn't audit your ears a single time today. Ordinary workplace sound stops feeling like an incoming threat. Your brain begins letting the noise sit in the background while your focus returns to your work.
Full workday mental bandwidth is restored. You lead meetings, complete complex tasks, and sit in busy environments without internal sound-auditing. You no longer dread your shift schedule or consider quitting your job.
The over-reactive signaling loop is disarmed. Because you stopped fearfully auditing every sound, you stopped feeding the high-gain central engine. You live, work, and socialize normally around ordinary sound without fear.

"My sinus infection cleared in October, but office noise started giving me severe tinnitus spikes. I was sitting at my desk frantically auditing my ears every 10 minutes and seriously considering handing in my resignation because I thought work was destroying my hearing. My doctor told me my ears were clean and to 'manage stress.' Week three on Noxtee, I finished a 9-hour shift, drove home, and realized I hadn't checked my ears once all day. My focus is back and I kept my career."
Glycine — 3,000mg. Three full grams. Glycine is the primary inhibitory neurotransmitter used by the central nervous system to apply the "brakes" on over-firing neural relays. It refills the inhibitory reserves of the Dorsal Cochlear Nucleus so ordinary sound stops triggering exaggerated spikes.
Magnesium Bisglycinate — 200mg. Chelated directly to glycine for high central nervous system bio-availability. It regulates NMDA receptor activity to help prevent neural hyperexcitability and hold the relay steady through demanding workdays.
L-Theanine — 200mg. Dampens the fight-or-flight alarm response, helping your nervous system step down from the high-stress, hyper-vigilant state accumulated during sound-auditing workdays.
Standardized Saffron Extract — 28mg. Pure standardized clinical extract that works sequentially to bridge nighttime rest, helping you wake refreshed with lower baseline reactivity.
Two capsules 30–60 minutes before bed with water. Zero melatonin, zero morning grogginess.
When an ear infection or fluid buildup muffles sound, your brainstem's Dorsal Cochlear Nucleus (DCN) turns up its central gain to compensate.
Even after your infection clears and your ENT declares your ear canal "clean," the relay's built-in inhibitory brakes remain weakened. When you enter a noisy or demanding workplace, normal ambient sound triggers hyper-reactive signaling that you experience as a tinnitus spike.
You misread the spike as "fresh ear damage" and start constantly auditing your ears. This hijacks your mental bandwidth, destroying your concentration at work.
Noxtee provides full clinical doses of glycine and magnesium bisglycinate to support the relay's inhibitory brakes, combined with L-theanine and saffron to wind down daytime stress arousal. As the relay stabilizes, ordinary safe sound feels ordinary again, sound-auditing stops, and your focus returns to your job.

I had a severe ear cold in November. The doctor said my eardrum was healed, but every shift at my job triggered a massive ringing spike. I was sitting at my desk with half my brain trying to work and half panicking that ambient office noise was giving me permanent hearing loss. I almost handed in my resignation. Found Noxtee on a forum. By week three, I worked a full 9-hour day and realized on my drive home that I hadn't checked my ears once. It saved my job and my sanity.

Tried ear drops, sound masking, and expensive Amazon supplements after a middle ear infection. Zero results. Noxtee is the first thing that explained WHY it happens (the volume relay in the brainstem) instead of trying to squirt drops in a clean ear canal. 5 weeks in and I sleep straight through and work my shifts without panic.
Verified Customer
The workday checking stopped. I used to spend my entire shift rating the ringing volume against the hour before. Week three on Noxtee, I got through a 10-hour day, focused on my projects, and completely forgot to audit the noise. Stopped feeding the fear loop. 🙏

I teach middle school. After a fluid buildup in my ear, classroom noise became unbearable. I felt like every school day was destroying my ears, and I was terrified of losing my career. My ENT found nothing wrong. Noxtee was the first thing that explained that my brainstem relay was over-reacting to safe sound. Four weeks in, I can teach my classes without fear or brain fog.
Verified Customer
My ENT said my ear canal was pristine. Meanwhile I couldn't sit through a meeting at work without my head buzzing and losing focus. Three weeks on Noxtee and my sound tolerance 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.

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.
