How Do You Check a ZenCortex Batch or Lot Number?
To check a ZenCortex batch number, read the lot reference on your bottle and compare the label with the typed Supplement Facts. The seller gives lot ZEN-26/TH-7233 and a CoA reference ZEN-7233-26-TH. Those codes are seller references. We have seen no lab report, so they do not prove purity, potency or safety.

Lot codes01
What is a ZenCortex batch or lot number?
A ZenCortex batch or lot number is a code that groups bottles made at the same time, so a seller can trace them if a problem comes up.
The seller gives lot ZEN-26/TH-7233 and a certificate of analysis (CoA) reference, ZEN-7233-26-TH. Both are references we were handed. We have not seen the document behind either one, and we do not know who would have issued it.
A code on its own proves nothing. Anyone can print a code on a label. What a CoA would prove depends on who tested, what they tested for and what the report says. We have seen none of that, so we treat both codes as seller references and not lab proof.
Where to look on the bottle
Look at the back label, near the base of the bottle and on the cap seal. A lot code is often printed with an expiration date. We could not confirm where ZenCortex prints its code, so check all three spots.
How to read it02
How do you check a ZenCortex bottle step by step?
Check a ZenCortex bottle in five steps: seal, front label, back label, lot code and seller.
Check the safety seal
The label says not to use the product if the safety seal is damaged or missing. Return or report a bottle with a broken seal.
Read the front
It should say ZenCortex, "Supports Healthy Hearing†", Hearing Support Formula, Dietary Supplement and 60ML / 2 FL OZ.
Read the back
Serving size 1 mL, 60 servings, chromium 0.7 mcg, a 200 mg Proprietary Herbal Blend of 22 lines, and the distributor line.

What matches03
What should a genuine ZenCortex label show?
A genuine ZenCortex label shows a 60 mL bottle, a 1 mL serving, chromium at 0.7 mcg, a 200 mg blend of 22 lines and a distributor in Aurora, Colorado.
Use the table to compare. A mismatch does not prove a fake, because labels get updated, but it is a reason to ask the seller.
| Check | Expected on the label |
|---|---|
| Bottle | 60 mL (2 fl oz) amber glass, black cap and dropper |
| Serving | 1 mL (1 dropper), 60 servings |
| Chromium | 0.7 mcg, 2% Daily Value |
| Blend | Proprietary Herbal Blend, 200 mg, 22 lines |
| Other ingredients | Deionized water, organic citrus extract, natural flavors, stevia, xylitol |
| Distributor | ZenCortex, 19655 E 35th Dr #100, Aurora, CO 80011 |
| Claim | "Supports Healthy Hearing†" and the FDA statement |
Limits04
Does a ZenCortex lot number prove the bottle is safe or pure?
No. A ZenCortex lot number does not prove the bottle is safe, pure or strong, because a code is only a tracking label.
The label names no factory, no lab and no testing date, so the code points to nothing we can check. The brand's badges, such as GMP certified and registered FDA facility, are also claims with no certifier named. Read them in ZenCortex quality testing.
FDA does not approve supplements before they are sold (FDA, Dietary Supplements). It has also found drugs hidden in products sold as supplements, mostly in weight-loss, sexual-enhancement and bodybuilding items (NCCIH, Using Dietary Supplements Wisely), and keeps a public list of notices (FDA, Public Notifications - Health Fraud). A lot code does not tell you which category a bottle falls in.
A full lab report that names the lab, the method, the date, the lot and every result, tied to your lot. Ask the order desk for it, and if you get a short PDF with only a code, treat it as marketing.

What should you ask the seller about a ZenCortex batch?
Ask the ZenCortex order desk for the testing lab's name, the report for your lot and the manufacturer, since the label names none.
- Who made this lot, and where?
- Which lab tested it, and for what?
- Can I see the report for my lot code?
- What does the CoA reference ZEN-7233-26-TH link to?
- Where is the expiration date printed?
Call +1 (380) 868-3839 with your order ID. Write down who answered and what they said. If you cannot get an answer, you may use the 60-day guarantee, described on the guarantee page.
"Made in USA" sits on a brand badge, but the label names no factory. We cannot say where the drops are made.
If something is wrong06
What should you do if a ZenCortex bottle looks wrong?
If a ZenCortex bottle looks wrong, stop using it, keep it and call the order desk. A broken seal, a changed smell or an odd label are all reasons to stop.
Take photos of the seal, label and lot code. Keep the bottle, and the box if you have it. If you feel unwell after taking it, call a clinician and report the problem to FDA through MedWatch (FDA, MedWatch). Keep taking prescribed medicine as directed.
Keep the bottle away from children and pets. Xylitol, listed under other ingredients, is toxic to dogs (FDA, Xylitol Is Toxic to Dogs).
FAQ07
ZenCortex questions people ask
Where is the lot number on a ZenCortex bottle?
We could not confirm the spot. Check the back label, the base of the bottle and the cap seal. If you cannot find a lot code, call the order desk on +1 (380) 868-3839 and ask where ZenCortex prints it.
Can you verify ZenCortex lot ZEN-26/TH-7233 online?
We found no public lookup tool for it. The code is a seller reference. We have not seen a lab report for the lot, so the code cannot be checked against any independent record.
What is the ZenCortex CoA reference ZEN-7233-26-TH?
It is a certificate-of-analysis reference supplied by the seller. We have not seen the document, the lab or the results. Until a full report is shown, treat the code as a seller reference and not proof of quality.
Does ZenCortex print an expiration date?
We could not confirm an expiration date from the material we read. Look on your bottle and the box. If none is printed, ask the order desk how long an unopened bottle keeps and how long after opening.
How can you tell if a ZenCortex bottle was tampered with?
Look at the safety seal first. The label says not to use the product if the seal is damaged or missing. Also check the cap, the label edges and the dropper for signs of opening, and call the desk.
Is a ZenCortex bottle from a marketplace safe to use?
We cannot confirm any marketplace listing. If you have one, compare its label with the typed panel, check the seal and lot, and ask the order desk whether they can match it to an order. Used or opened bottles are best skipped.
Who manufactures ZenCortex?
The label names a distributor in Aurora, Colorado, and no factory. The brand badge says made in USA, but no facility is named. Ask the seller for the manufacturer and the testing lab.
