How To Check Your BreathiZen Batch

Read the lot off the bottle, call the desk, match it to your order. Three steps, one phone call.

Last updated September 22, 2026By BreathiZen Editorial DeskReading time 6 min

BreathiZen currently ships against lot BRE-26/BR-6580, with a certificate of analysis reference of BRE-6580-26-BR. The lot number is printed on the base of the bottle where the bottle shows it, alongside a best-before date. To check a bottle, read the lot number and call +1 (302) 200-3480 with your order ID so the desk can match the two.

Checking a bottle

The three steps

  1. Find the lot number

    Turn the bottle over. The lot number and a best-before date are printed on the base where the bottle shows them. Use a bright light: printing on amber glass is not always easy to read.

  2. Compare it with the published lot

    The current lot is BRE-26/BR-6580. A different lot is not automatically a problem, because lots change over time. It is a reason to call.

  3. Call the desk with your order ID

    Ring +1 (302) 200-3480. Read out the lot number and your order ID, and the desk can match your bottle against what was sent to you. This is the only check anyone can do from outside the factory.

Being precise about this

What a certificate of analysis is

A certificate of analysis, or CoA, is a laboratory report on one batch. A good one lists what was tested for, which laboratory did the testing, the date, and the result against a specification. It typically covers identity, potency, heavy metals and microbial contamination.

Here is the honest position for this product. A CoA reference number was supplied to this website: BRE-6580-26-BR. The certificate itself was not. We have not seen it, so we are not going to publish it, summarise it, or tell you what it says.

What that means, precisely

A CoA number on its own is not evidence of testing. It is a reference to a document. Until the document exists in front of you, the number tells you that a batch record system exists, and nothing more than that. We would rather say that plainly than print a number and let it look like proof.

If you want to see the certificate, ask the order desk for it on +1 (302) 200-3480. If the seller sends it to this website, we will publish it in full on this page and move the updated date forward the same week.

Limits

What checking a lot number can and cannot tell you

Honest limits of a batch check.
QuestionCan a lot check answer it?
Did this bottle come from the order I placed?Yes, by phone with your order ID
Is this bottle within its best-before date?Yes, it is printed alongside the lot
Is this the current production batch?Yes, compare it with the lot above
Was this batch tested?Not from the number alone
How much of each ingredient is in it?No. No amounts are published
Is a bottle bought on a marketplace genuine?Only partly. Call the desk

That last row is worth expanding. If you bought a bottle somewhere we did not sell it, the desk can tell you whether the lot number is one of theirs. It cannot tell you how that bottle was stored, how old it is, or what happened to it between the factory and you. That is the real risk with a marketplace listing, and no number resolves it.

Worth knowing

Best-before dates and multi-bottle packs

This matters more with a six-bottle pack than most buyers expect. Six bottles is roughly 600 days of product at one serving a day. The last bottle in that pack will be opened well over a year after it arrived.

Two practical consequences. First, check the best-before date on the base of each bottle before you open it, not just the first one. Second, where those bottles sat for a year decides what condition they are in. Keep the unopened ones boxed, cool, dry and out of the light.

  • Check the best-before date on every bottle before you open it.
  • Open them in the order they came, not at random.
  • Store unopened bottles in their box. Light is the enemy of a botanical extract.
  • If a bottle's date has passed, do not use it. Call the desk instead.
  • If the liquid looks or smells different from the previous bottle, stop and call.
FAQ

Batch questions

Where can I buy BreathiZen?

Through this website, which is the USA Authorized BreathiZen Retailer. Buying here means your order, your tracking and your refund all sit with one order desk.

Is BreathiZen sold on Amazon or in stores?

We do not sell it there and we cannot vouch for anything sold there. A third-party listing is outside the guarantee described on this site.

Is BreathiZen a scam?

It is a real product from a seller with a US phone number, a named office, a returns address and a published lot number. What it does not have is a published Supplement Facts panel, and that is a fair reason to be cautious. Buy one bottle, keep the order email, and use the window.

How do I contact a human?

Call +1 (302) 200-3480 for anything about an order. Email [email protected] for anything about this website. The desk is open Monday to Friday, 9:00am to 5:00pm ET.

Does it need refrigeration?

Not published on the artwork we were given. Store it somewhere cool, dry and out of sunlight, and keep the cap closed.

The background

Why lot numbers exist at all

A lot number is the thread that connects a bottle in your hand to a specific production run. Every ingredient that went into that run, the date it was made, the equipment it passed through and any testing done on it are filed against that one code.

This is not a marketing feature. Batch control is required by 21 CFR Part 111 (Electronic Code of Federal Regulations), the rule that governs how US supplements must be manufactured. Any manufacturer working to that standard keeps batch records, because without them a recall would be impossible: there would be no way to know which bottles were affected or where they went.

That is the practical value to you. If a problem is ever found with a production run, the lot number is what tells you whether your bottle is in it. It is a small code that does one important job badly explained on most supplement websites.

What a lot number is not

It is not a serial number. Thousands of bottles share one lot, so a matching lot does not prove your specific bottle came from us, only that it came from that production run. It is also not a test result, not a certificate, and not a guarantee of anything about the contents. It is a filing reference.

Practical

Storing a multi-bottle pack properly

This section exists because the six-bottle pack is the one most people buy and the one with the longest tail. Six bottles at one serving a day is roughly 600 days. The last bottle will be opened well over a year after it arrived, and where it spent that year decides what state it is in.

Storage, and why each row matters for a botanical liquid.
DoWhy
Keep unopened bottles in their boxCardboard is a light barrier. Amber glass blocks most damaging wavelengths, not all
Store somewhere cool, dry and darkHeat accelerates the breakdown of plant compounds. A kitchen cupboard away from the hob beats a windowsill by a wide margin
Avoid the bathroomHumidity and repeated temperature swings are the two worst conditions for a liquid supplement, and a bathroom cabinet has both
Open bottles in orderUse the oldest first. Bottles in one pack can carry different best-before dates
Check the base before each new bottleThe best-before date is printed there with the lot. Check it at bottle four, not only at bottle one
Keep the pump cap closedAn open spray mechanism can dry out and clog, which changes your dose without you noticing

When to stop using a bottle

If the best-before date has passed, if the liquid has changed colour or smell compared with the previous bottle, if the pump has stopped delivering a full spray, or if the seal was broken on arrival. In all four cases, stop and call +1 (302) 200-3480 rather than deciding for yourself.

A two-minute call

Batch checking, step by step on the phone

People often put off calling because they are not sure what to say. The whole call is four sentences and it takes about two minutes.

  1. "I want to check a bottle against my order." That tells the desk which kind of call this is.
  2. Read out your order ID from the confirmation email.
  3. Read out the lot number from the base of the bottle, character by character. Amber glass is hard to read, so use a bright light and read it twice.
  4. Ask whether the two match, and whether the best-before date on your bottle is the one they expect for that lot.
  5. If anything does not line up, ask what they want you to do next and write the answer down.

If you bought the bottle somewhere other than this website, say so at the start. The desk can still tell you whether the lot is one of theirs, and being straight about where it came from gets you a more useful answer than pretending otherwise.
