Check your bottle against the page
When your bottle arrives, hold it beside the panel page. The order page shows the packs and the 180-day guarantee if anything does not match.

What is the Quiettone lot number?
The quiettone lot number on the stock this site describes is QUI-26/QU-5380. A second code, QUI-5380-26-QU, is called the certificate reference. Both come from the distributor's paperwork. The site prints them exactly and then says what they are worth, which is less than a buyer might hope.
A lot number names a production run. It is how a maker traces a bottle back to a date, ties a complaint to a run and recalls one run without recalling all of them. Those are traceability jobs. They are real and useful. They are not test results.
Where do you find the Quiettone lot number on the bottle?
The lot is inkjet-printed, not part of the printed label. It sits usually on the base of the bottle or along the bottom edge of the back label, with a best-before date next to it. If your bottle has no stamp at all, call the order desk on +1 (302) 200-3480 and say so.
The best-before date is the one field that changes by design from run to run. The other three things that can change are the artwork layout, the other-ingredients line and the panel itself. The panel is the one that matters.
What six checks can you make on a Quiettone bottle?
All six need only the bottle and this website. Do them before the first capsule.
| Check | What to look for |
|---|---|
| Lot stamp | A lot and a best-before date, inkjet-printed |
| Panel | Ten rows: nine with an amount and a percent Daily Value, plus one 415.5 mg blend row with a dagger |
| Other ingredients | Hypromellose (vegetable capsule), magnesium stearate (vegetable), silicon dioxide |
| Count | 30 capsules, one per serving, 30 servings per container |
| Seal | The label says not to use the bottle if the safety seal is damaged or missing |
| Distributor block | Quiet Tone, PO Box 12730, Ogden, UT 84404 |
If the ten rows on your bottle differ from the transcription on the supplement facts page, the bottle wins. A new row, a changed weight or a new blend total can mean the formula was revised. Tell the website desk the lot and what differs, and the page gets corrected.
What can a quiettone lot number prove?
Here is the split in two columns of plain facts.
- It can show which production run a bottle came from.
- It can show whether two bottles came from the same run.
- It can give a route back to a production date if a complaint is raised.
- It can let a maker recall one run, not all of them.
And what it cannot do:
- It cannot show the capsule holds what the panel says.
- It cannot show that anyone tested it, in-house or outside.
- It cannot show that a lab has seen this run or any run.
- It cannot show that heavy metals or microbes were screened.
The certificate reference is in the same position. A real certificate of analysis names a lab, a method, a date and results. Nothing like that is published here.
What should you ask the order desk about the lot?
Three questions are fair, and none is a trap. Ask for the certificate of analysis for your lot, quoting the lot from your bottle. Ask for the name of the manufacturing facility, since the label prints a distributor, not a maker. And ask whether any third-party test exists.
The likely answers are that a reference exists, that the document is not published and that no third-party result is published. That is common in this category, but asking is still worth it. A seller that hears the question often enough may publish. Our FDA approval guide covers the seals on the carton, and the home page shows the full label.
Does a lot number make a bottle safe or real?
A lot code helps you check that a bottle matches the paperwork. It does not make the contents safe, and it does not make the product work. It also does not protect you from a resold bottle, since a reseller can pass on any lot. The 180-day refund window is a policy for orders the seller can see, so buying through the official page matters more than any code.

Frequently asked questions

My panel does not match the website. What now?
The bottle is the authority. Write to the website desk with the lot and the row that differs, and call the order desk if you want a refund.
Is Quiettone third-party tested?
No third-party result is published. The seals on the carton describe a process, an origin and a refund, not a test.
Our view
Our view is that the lot number is a useful tool for the right job. Use it to match a bottle to the paperwork and to trace a problem. Do not use it as a quality score.
The honest position is that identity, potency, metals and microbe results are not published. That is common, but it is still a gap. Weigh the printed panel, the price and the guarantee, and check your bottle against the page the day it arrives.
Quiet Tone is not FDA approved, and no supplement is. The statements on this page have not been evaluated by the Food and Drug Administration.
