FemiCore Lot Number and Seal: How to Check Your Bottle
A FemiCore lot number is the batch code stamped on your own bottle, separate from the printed label artwork. The seller's references are lot FEM-26/MY-2942 and CoA FEM-2942-26-MY, but they are codes, not lab proof, and no certificate of analysis is published. Check four things yourself: the stamp, the seal, the label text and where you bought it.

The stamp
Where is the FemiCore lot number on the bottle?
The FemiCore lot number is not part of the printed label design, so look for a separate stamp. The flat label artwork we read carries no lot code and no date anywhere on its three panels.
On most supplement bottles, the lot and date go on after filling, as a small ink-jet or embossed line. Check the base of the bottle first, then the shoulder near the cap, then any blank strip on the label edge.
Hold the bottle under a bright light and tilt it. Ink-jet print is thin and can be pale on white plastic. Write the code down or take a photo, because you may need it if you ever ask for a certificate of analysis or report a problem.
- Base of the bottle: the usual place for a lot and date
- Shoulder or neck, just under the cap
- A clear strip on the label's edge
- The cap's inner seal does not carry it; do not peel it to look
The codes
What are FemiCore lot FEM-26/MY-2942 and CoA FEM-2942-26-MY?
They are reference codes the seller supplied for this site, not lab documents. Lot FEM-26/MY-2942 and CoA FEM-2942-26-MY tell you which batch the seller points to; they do not show what a test found.
A certificate of analysis is a one-batch report. It lists each test, the limit allowed and the result. Without the document, the code is like a receipt number with no receipt attached.
Your own bottle may carry a different lot from the seller's reference. That is normal: batches change over time. What matters is that your stamp is clear, matches nothing odd and can be quoted if you ask the brand a question.
| Code | Where it comes from | What it is | What it proves |
|---|---|---|---|
| FEM-26/MY-2942 | The seller's brief | Lot reference | Nothing about content on its own |
| FEM-2942-26-MY | The seller's brief | CoA reference | Nothing until the report is shown |
| V1 | Printed up the label's left edge | Likely the label version | Which print run of the artwork it is |
| Your stamp | Base or shoulder of your bottle | The batch your capsules came from | Traceability, if the brand keeps records |
Edge code
What does the V1 on the FemiCore label mean?
V1 is most likely the label's version number, not a lot number. It runs in small type up the left edge of the flat label, beside the directions and the FDA box.
Brands often number their label artwork so the printer knows which file to use. A later redesign would usually read V2. That tells you about the paper wrap, not about the capsules inside.
What the left panel holds
Suggested use, the caution, "keep out of reach of children", the safety seal line, storage, the FDA statement box and three printed marks. The V1 sits along the edge of this panel.
Compare your bottle with the full transcript on the FemiCore supplement facts page.

The seal
How do you check the FemiCore safety seal?
Check the seal before the first capsule, and do not use the bottle if the seal is damaged or missing. The label says exactly that: "Do not use if safety seal is damaged or missing."
The seal is the foil or plastic layer under the cap that you peel off on first use. It is the only sign that nobody has opened the bottle since it was filled.
Look at the cap
It should screw on snugly, with no cracks and no sticky residue around the rim.
Open and inspect
The inner seal should cover the whole mouth, flat and unbroken, with no pinholes or lifted edges.
Check the capsules
Count is 30. Capsules should be dry and whole, not cracked, clumped or damp.
Photograph any fault
A clear photo of a torn seal helps the order desk sort out a replacement or return.
Fakes
How can you spot a fake FemiCore bottle?
A fake bottle usually gives itself away on the label text. Compare yours line by line with the genuine label; a copy often gets the small print wrong.
Start with the parts that are hardest to copy well: the full ingredient list, the distributor address and the exact wording of the caution. Any mismatch is a reason to stop and ask.
Matches the genuine label
- "FEMI CORE" in a hexagon panel with silver-blue ornaments
- Herbal Blend 350 mg and Probiotic Blend 50 mg
- Nine named lines, with strain codes such as LCr86 and LC16
- Gelatin capsule listed first under other ingredients
- Distributor in Tallmadge, OH 44278
- 30 capsules, one a day with 6-8 oz of water
Reasons to stop and ask
- A different capsule count or serving size
- Only six ingredients, or no strain codes
- Single amounts or a CFU count on the panel
- A distributor address other than Tallmadge
- No FDA statement box, or a missing seal
- No lot stamp anywhere on the bottle
Printing single amounts is not wrong in itself; it simply does not match the label FemiCore uses. Our research also found many "review" pages on unrelated sites, most of them paid press releases. Treat them as ads, not as a seller list.

See packsDates
Where is the FemiCore best-before date?
Look next to the lot stamp. Like the lot number, a best-before or expiry date is not in the label artwork, so it is normally stamped on the bottle with the batch code, often marked "EXP" or "Best by".
The date matters more than usual for a capsule with live cultures. Probiotics must be alive to work, and the count that counts is the one at the end of shelf life (NIH ODS, Probiotics). FemiCore prints no count at all, which makes the date your only clue to freshness.
If you find no date, ask the order desk before you start the bottle. Keep it in a cool, dry place, as the label asks, so the capsules do not age faster than the stamp says.
Buying
Where should you buy FemiCore to avoid fakes?
Buy through the official FemiCore checkout, run by BuyGoods, which is where the order buttons on our site lead. A bottle from that checkout has an order ID the desk can trace.
Bottles from auction sites or unknown shops have no such trail. If something is wrong with one, nobody may be able to tell you which batch it came from, and the 60-day guarantee may not reach it.
Official checkout
Order ID, tracking and the order desk at +1 (302) 200-3480.
Unknown reseller
No order ID with the desk, an unclear batch history and no guarantee we can confirm.
Ad-style review pages
Often paid press releases on unrelated domains. Do not order through their links.

If it fails
What should you do if your FemiCore bottle fails a check?
Do not take the capsules. Set the bottle aside, photograph the problem and call the order desk at +1 (302) 200-3480 with your order ID.
Keep the bottle, the box and the packing slip together. If you bought outside the official checkout, the brand's own email on the label, [email protected], is the place to send the lot code and photos.
The website inbox can take a note about a suspicious listing, but it cannot see orders. More on who answers what is on the FemiCore contact page.
Stop the supplement and call a doctor. Keep taking prescribed medicine unless your doctor says otherwise. The FDA asks people to report serious reactions to a supplement, such as trouble urinating or blood in the urine, through its Safety Reporting Portal; partial details still help (FDA, Report a Supplement Problem).
FAQ
FemiCore lot and seal questions
What is a lot code on a FemiCore bottle?
A lot code is the batch number stamped on your bottle when it was filled. It lets a brand trace which raw materials and which production run your capsules came from. FemiCore's printed label artwork has none, so look for a separate ink-jet or embossed stamp, usually on the base of the bottle.
Is it safe to use FemiCore if the seal is broken?
No. The label says not to use the bottle if the safety seal is damaged or missing. A broken seal means you cannot know whether the capsules were opened or swapped. Take a photo, keep the bottle and call the order desk with your order ID to ask about a replacement or return.
Are fake FemiCore bottles sold online?
We have no report of a specific fake, but any popular supplement can be copied, and unknown resellers leave no batch trail. The safest route is the official checkout. Compare your label with the genuine one: nine lines, two blend weights, gelatin capsule and the Tallmadge, Ohio distributor.
Does FemiCore have an expiration date?
It should carry one, but the date is not in the printed label artwork. Look beside the lot stamp for a mark such as EXP or Best by. If your bottle has no date at all, ask the order desk before starting, because the five cultures need a fresh product to count.
Can I see the FemiCore certificate of analysis?
Not yet. The seller gave us a CoA reference, FEM-2942-26-MY, but no report has been published. A real CoA lists tests, limits and results for one batch. You can ask the brand for the report for your lot by writing to the distributor email printed on the bottle.
Is the V1 on the FemiCore label a batch number?
No. The small V1 up the left edge of the label is most likely the version of the label artwork, the way a document might be marked version one. It is identical on every bottle printed from that file, so it cannot identify a batch. Your lot number is a separate stamp.
