  • Ingredients

The ringing isn't coming from your ears. It's coming from the nerve behind them.

The nerve that carries sound from your ear to your brain is wrapped in a thin protective cover. That cover is kept alive by a cellular fuel called NAD+. When the fuel runs low, the cover frays, the bare fibers spark, and your brain hears every spark as sound.

Read more ⌄

By the time you hit your 50s, the NAD+ your body makes has dropped by about half. Years around loud noise, an illness, even the meds you've been on burn through what's left. That's why the ringing gets louder in the quiet, one ear becomes both, and a faint whine at night becomes a constant ring by day.

Hearing aids, ear drops, sound machines and white noise apps are all aimed at your ears. The nerve keeps starving, and the sparking only gets louder. It isn't permanent ear damage. It's a deficiency, and a deficiency can be fed.

Doctors call the sound tinnitus, but that only names the sound. The cause sits further in.

The nerve that carries sound to your brain has a thin protective cover, like the rubber around a phone charger cable. That cover wears a little every day. Your body repairs it, and the repair runs on a fuel called NAD+. When the cover wears faster than your body can repair it, the bare nerve sparks, and your brain hears every spark as sound.

That's also why a hearing test can come back normal. The test checks the quietest beep you can hear. It doesn't check the nerve that carries it, so a worn nerve passes every time. Researchers call this hidden hearing loss.

CelluNAD+ works differently than fans, sound machines and hearing aids. It doesn't cover the ringing. It gives your body back the fuel it uses to repair the nerve.

If you want to read the research yourself, here are some of the studies behind the ingredients:

Take two droppers (2 ml) under your tongue once a day. Shake the bottle, hold it under your tongue for 30 seconds, then swallow. First thing in the morning works best, and you can drink coffee or eat right after.

What matters is consistency. Nerve repair takes time, so steady daily use is what builds results.

Here's what most customers report:

  • Weeks 1 to 3: Falling asleep faster.
  • Weeks 3 to 5: Quieter days.
  • Week 5 on: Whole days you forget the ringing is there.
  • Ongoing: Your body makes less NAD+ over time, so keep taking it to keep the repair going.

Score the ringing from 0 to 10 when you wake up. Most customers see the number move before they notice it any other way.

One note: If you are pregnant, nursing, on blood thinners, or managing a medical condition, check with your doctor first.

The Science Behind CelluNAD+

1

The Cover Wears Thin

The nerve that carries sound to your brain has a thin protective cover, like the rubber around a phone charger cable. By your 50s, the NAD+ fuel your body uses to repair it has dropped by about half. When the cover wears through, the bare nerve sparks, and your brain hears every spark as sound.

2

The CelluNAD+ Refuel

CelluNAD+ puts 300mg of NR, liposomal delivery, and the B vitamins that switch it on into two droppers under your tongue. It skips your stomach and reaches your cells in minutes.

3

The Cover Repairs

Your body repairs that cover every night, and the repair runs on NAD+. With the fuel back, the repair can finish.

4

The Ringing Quiets

Your body already knows how to repair that nerve. It just ran out of the energy to do it. Most customers report falling asleep faster in week 1, quieter days by week 3, and whole days they forget it's there by week 5.

Your Transformation Timeline

What most customers report in their first 90 days.

Phase 1

WEEKS 1-2 | Refueling

You're building NAD+ back up where the nerve needs it. Most people don't hear a big change yet, and that's normal. Many notice they fall asleep faster first. Stay consistent. The repair is already underway.

Phase 2

WEEKS 3-4 | Quieter Days

This is when most people start noticing. The evenings get quieter. The fan goes off. The ringing that sat in the background all day starts to fade. These early wins are the sign the nerve's cover is repairing.

Phase 3

MONTHS 2-3 | Whole Quiet Days

Bigger changes settle in. The people around you notice you're calmer. Quiet rooms stop being something you dread. You sleep through the night, and there are whole days you forget the ringing is even there.

Phase 4

MONTHS 4-6 | The Quiet Stays

For people who've heard it for years, this is where the real change happens. The nerve's cover has repaired and the sparking has settled. What once felt out of reach, silence, sleep, a quiet room, now feels normal. And the quiet stays.

Common Questions

Everything you need to know about the ringing, results timelines, and what to expect

What does CelluNAD+ actually do for the ringing?

CelluNAD+ is a cellular fuel restoration formula. It gives your body back the NAD+ it has run low on, so the nerve that carries sound to your brain can go back to repairing itself:

  • Repairing the worn cover on the nerve
  • Keeping that repair going overnight, when most of it happens
  • Supporting deeper sleep, so the repair isn't cut short
  • Adding no sound, with nothing going in your ear
Do you guys sell on Amazon?

No. CelluNAD+ is only sold on our site.

We handle every order and every refund ourselves, so you are never sent to Amazon or a marketplace to chase your money.

How long until I notice a difference?

Everyone is different, but many customers notice they fall asleep faster within the first 1 to 3 weeks, and quieter days around weeks 3 to 5.

The easiest way to tell: score the ringing from 0 to 10 when you wake up and write it down. Most customers see the number move before they notice it any other way. Check it at week 1, week 3 and week 5.

Nerve repair takes time, so we recommend a full 90 days, every day, first thing in the morning. That is why the guarantee covers all 90 days.

I've tried Lipo-Flavonoid, ginkgo and zinc. Why would this work when nothing else has?

Lipo-Flavonoid, ginkgo and zinc are vitamins and herbs. CelluNAD+ restores the fuel your nerve uses to repair itself.

Two problems with the pills you already tried:

  • Up to 90% is destroyed by stomach acid before it reaches a single cell
  • Even what arrives isn't the fuel the nerve needs, so nothing gets repaired

CelluNAD+ is liposomal drops held under the tongue, so it skips the stomach. And every dose is printed on the label, with no proprietary blend.

Is it safe to take with my medication or the supplements I already take?

CelluNAD+ is drug-free, and many customers take it alongside their regular medication and the supplements they already take, including magnesium. It already contains 50mg of magnesium glycinate, and you don't need to add anything else for it to work.

As with anything new, please check with your healthcare provider first, especially if you are pregnant, nursing, on blood thinners, or managing a medical condition.

What's actually in it? Will it cause side effects?

Every dose (2 ml) delivers clinical-range amounts, wrapped in liposomes:

  • Nicotinamide Riboside (NR) 300mg, the cellular fuel restorer
  • TA-65 astragalus extract 25mg, protects DNA during repair
  • CoQ10 50mg, restarts the cell's power plants
  • Pterostilbene 50mg, antioxidant shield for repairing cells
  • TMG 50mg with vitamin B6, B12 and folate, switches the fuel on
  • Magnesium glycinate 50mg, sleep support

It adds no sound, and nothing goes in or near your ear. Most customers transition smoothly. A few notice a light flush or extra energy in the first days as NAD+ levels come back up, which settles quickly. If you feel unwell, stop taking it and speak with your doctor.

What if it doesn't work for me?

It is a 90-day, no-questions-asked guarantee.

Use every drop of your supply, then decide. If the ringing hasn't changed, email us within 90 days and we refund you in full. No questions asked.

What happens if I stop taking it?

Your body makes less NAD+ over time, and the everyday wear on the nerve doesn't stop. So we recommend you keep taking CelluNAD+ to keep the repair going.

It is a small daily habit: two droppers under your tongue in the morning, about 10 seconds.

Why hasn't my doctor mentioned the nerve?

Because it isn't a simple "ear" problem, and the standard tests don't look at the nerve.

A hearing test checks the quietest beep you can hear. It doesn't check the nerve that carries it, so a worn nerve passes every time. That is why so many people hear "your hearing is fine" and get told to learn to live with it.

Where is CelluNAD+ made, and how is it tested?

CelluNAD+ is made in a GMP-certified facility in the USA.

Every batch is third-party tested by Eurofins, so an outside lab confirms the bottle has what the label says. It is non-GMO, raspberry flavored, with no artificial sweeteners.

Will it work if I've had the ringing for years?

Many of our customers have had the ringing for 10 or 20 years, from a loud job, years of headphones, an illness, or no cause anyone could find.

What we can say is that a worn nerve needs the same fuel to repair whether it has been 2 years or 20. That is why the guarantee gives you a full 90 days to find out.

Recommending to my clients

I've had a faint ringing since my twenties and assumed nothing could touch it. A few weeks into using the drops daily I noticed I was falling asleep faster and the evenings were quieter. I now suggest CelluNAD+ to clients who tell me the ringing is the last thing they hear at night.

I got tinnitus from 22 years in the Marines. Gunfire, helicopters, engines. My ears took a beating. I tried everything after I retired. Supplements from Amazon, a $400 sound program, even acupuncture. Nothing touched it. My wife found these drops on Facebook and I told her it was probably another scam. She ordered them anyway. First week, the ringing went from a constant scream to a hum I could ignore. For the first time in 7 years I sat on my porch in the morning and actually heard the birds. I take it every morning now. My wife says I haven't slept this well since before my second deployment.

I almost didn't order it. I've been burned by so many things that promised to stop the ringing. But 6 weeks in I sat through an entire movie without the whine pulling me out of it. Forgot what that was like. Got a little emotional honestly.

I was skeptical, and I was so wrong. My brother had ringing that pills never touched, and I started getting the same. One night I was up crying because I couldn't sleep over the noise. My wife remembered I'd ordered these drops, and it was like a switch flipped. The ringing eased off fast. I also gave a bottle to my mom, who's had ringing for as long as I can remember, and now she can get through a quiet evening again. This is my fourth order. Our whole family uses it.

The quiet actually stayed

I've spent thousands on things that promised to stop the ringing. None of them worked. CelluNAD+ cost me less than a nice dinner and the quiet actually stayed.
