Nightly neural calm · Made in the USA
The ringing is real. So is the science behind it.
Quietra is a research-backed formula built around the two natural brakes your nervous system uses to quiet a signal — magnesium and glycine — at the doses the studies actually used.

Made for you if
You've already tried the things that didn't work.
Most people who find us have been through the whole list. We're not going to pretend that didn't happen, and we're not going to promise silence.
- Your hearing test came back normal — and the ringing is still there
- You've tried magnesium before, and it was the cheap oxide form
- Sound apps and fans help until you turn them off
- Someone told you to live with it
What's actually inside
Four actives. Every dose printed.
No proprietary blend, because a blend is how a label hides how little is in the bottle. Here is the entire formula and what each one is there to do.
Magnesium Bisglycinate
One of the two brakes. The bisglycinate form is chosen for absorption — not the oxide most cheap supplements use.
Bisglycinate chelateGlycine
The second brake, and an inhibitory neurotransmitter in its own right. 3g is the dose used in the published sleep trial — not the 500mg gesture.
Free-form amino acidL-Theanine
Works on the daytime stress load that wears the brakes down before bed. The trial-grade dose.
From Camellia sinensisSaffron Extract
The mood and sleep-quality research dose, standardised — the same amount used in the published randomised trials.
Crocus sativusWhat changes
Not the sound. The night around it.
Bedtime
The part of the evening you have been dreading stops being the worst part of the day.
The room
No fan, no TV, no app running all night just to cover it.
3 AM
You wake, you roll over, you go back down — instead of doing the arithmetic.
Morning
The first thing you do is not check how loud it is today.
In their words
Including the ones that aren't glowing.
Machinist, 38 years. Ringing since my fifties. I'll say what nobody else will: the sound is still there. Don't buy this expecting silence. Buy it for what happens after you hear it — I go back down now instead of staring at the ceiling till the birds start. That's what I paid for and that's what I got.
Finally something that isn't just magnesium oxide in a capsule and a prayer. Real doses, printed on the label, the right forms. Took about three weeks to feel the nights change, so give it the window. But once it settled in — the difference is real.
The 3am math stopped. Just stopped. Twenty years of lying there counting the hours I had left before the alarm — I honestly thought that was my new normal. It wasn't.
What to expect
This takes weeks, not nights.
Magnesium and glycine reload over weeks. Anyone promising you a first-night result is selling you something else.
- Evenings feel a little less braced
- Most people notice nothing else yet
- Fewer wake-ups than the week before
- Falling back asleep takes less effort
- The nights stop being the thing you plan around
- Partners tend to notice before you do
- You stop checking how loud it is first thing
- The sound is still there — the night around it isn't the same

Keep what's left. Get your money back.
Take it for 90 nights. If nothing about your nights changed, email us and we'll refund the order — you don't need to ship anything back. The guarantee is deliberately longer than the time the formula needs, so trying it costs you nothing but the wait.
Start with one quiet night.
