How Do You Check A Femicore Lot Number, And How Should You Store The Capsules?
Check the base of the bottle for a lot code and best-before date, and compare the lot with FEM-26/FE-3921, the stock this desk holds. A lot code traces a production run. It is not a potency, purity or colony test. Store the capsules in a cool, dry place, because the label says so.
Two small things on a bottle get ignored: the stamp on the base and the line that says where to keep it. For a capsule that holds live organisms, both matter more than usual.
This page shows where to find the lot code, what it can and cannot tell you, and how to store the capsules so the bottle you paid for is the one you take. All facts come from the printed label and this site's batch page.
- The stock this desk holds is lot FEM-26/FE-3921, with certificate of analysis reference FEM-3921-26-FE.
- The lot code and best-before date are stamped on the base of the bottle, where the bottle shows them.
- This desk holds a certificate reference, not the laboratory report, and will not publish a document it has not read.
- A lot code is not a potency test, a purity test or a colony count.
- The label says: store in a cool, dry place, and keep out of the reach of children.
- The label says not to use the product if the safety seal is damaged or missing.
Where do you find the lot number on a Femicore bottle?
Turn the bottle over. The lot code and the best-before date are stamped on the base, side by side. Not every photo of the bottle shows them, because they are stamped on the physical bottle rather than printed in the label artwork.
Then compare the code with FEM-26/FE-3921. If yours is different, that is not necessarily wrong. Stock rotates over time, and a newer run will carry a different code. It is worth a call to the order desk on +1 (302) 200-3480 to confirm which run you hold.

What is a lot code for?
A lot is one production run. Everything in it shares raw materials, equipment and a period of manufacture. That shared history is the whole point of grouping bottles together.
The practical value is tracing. If a raw material turns out to be a problem, the maker can find exactly which bottles it went into. If a buyer reports an issue, the code narrows the check from a product to a batch. That is real and worth having.
What can a lot code not tell you?
A lot code is often shown next to a certificate number and a lab-style graphic, which invites the reader to think the contents were verified. Tracing and verifying are different things. Here is what the code is not.
Not a potency test
It says nothing about how much cranberry extract or any other ingredient is in the capsule. No amounts are published anyway.
Not a colony count
For five live strains the number that matters is how many are alive when you swallow one. A lot code does not carry that, and neither does the label.
Not a purity test
Heavy metals, microbial contamination and identity checks are laboratory questions, and the answers live in a certificate of analysis.
Not a storage record
The code says when a bottle was made. It cannot say what temperatures the bottle has seen since.
What does the certificate reference mean?
This desk lists a certificate of analysis reference, FEM-3921-26-FE, and holds that reference. It does not hold the laboratory report behind it and has not read the report. So it will not publish a certificate it has not seen.
That is less impressive than a scanned document, but it is honest. A reference number alone does not show what a test found. If the maker releases a certificate, this site will carry it and move the review date forward.

A bottle that comes with a traceable lot and a phone number that can match it to your order is worth having. The checkout shows today's price and the 60-day guarantee.

How should you store Femicore?
The label gives the instruction in four words: store in a cool, dry place. On most supplements that is boilerplate. Here it has content behind it, because the probiotic blend holds five live strains at a colony count nobody has printed.
Heat and moisture reduce the number of live organisms. The two places many people keep supplements, a bathroom cabinet and a sunny windowsill above a kitchen counter, are among the warmest and dampest spots in a home. A cupboard in a hallway is better than either and costs nothing.
What are three simple storage rules?
- Keep the bottle closed and out of direct sun.
- Do not tip the capsules into a pill organiser for weeks. A capsule left in open air absorbs moisture.
- Note the best-before date next to the lot code. With a six-bottle order, you may open the last bottle months after the first.
Keep the bottle out of the reach of children, as the label states. If a seal is damaged or missing when it arrives, do not use it. Call the order desk the same day, before the first capsule.
What about heat during delivery?
Here the facts run out. Nothing is published about temperature in transit, which is a fair question for a product with live organisms in a hot month. The carrier is not named in advance. A parcel is quoted at 5 to 7 working days inside the United States after handling.
What you can do is bring the parcel indoors promptly, check the seals, read the base of each bottle and then store the capsules as above. If you leave a parcel in the sun or in a hot vehicle, that is something to mention when you call the desk.
Does a bottle bought elsewhere carry the same lot?
Not necessarily, and this desk cannot tell. Femicore is sold through this website only. The retail desk does not supply pharmacies, supermarkets or gyms and does not run a marketplace storefront. A bottle bought elsewhere cannot be traced to lot FEM-26/FE-3921 through this desk, and it is not covered by the 60-day guarantee described here.
That matters more for a live-organism product than for a mineral tablet. If a bottle has sat somewhere warm, nobody can say what the count is now, because the count was never published to begin with.
What should you do when a bottle arrives?
A short checklist:
- Check the safety seal before you open the bottle.
- Read the base for the lot code and best-before date.
- Read the Supplement Facts panel against this site's label page, which shows 350 mg for the herbal blend and 50 mg for the probiotic blend.
- Store it cool and dry.
- Keep the packing slip and box until the 60 days have passed.
If anything disagrees with what this site says, call the order desk and say so. A correction changes the page. Femicore is a dietary supplement and is not FDA approved, so a lot code is a tracing tool and not a seal of approval.
Where do these facts come from?
- Femicore batch page on this site: the lot, the certificate reference and the four checks.
- Femicore label page on this site: the printed panel and the caution block.
- Femicore shipping page on this site: what is checked when a parcel arrives and what is not published.
- Femicore where to buy page on this site: why the channel decides traceability and the guarantee.
Frequently asked questions
What is the Femicore lot number?
The stock this desk holds is lot FEM-26/FE-3921, with certificate of analysis reference FEM-3921-26-FE. The code and best-before date are stamped on the base of the bottle.
Does a lot code prove a Femicore capsule is genuine?
It shows the bottle belongs to a production run this desk can identify. It is not a purity test, a potency test or proof of what is inside.
Can I see a Femicore certificate of analysis?
This desk holds a reference and not the document, and it will not publish a certificate it has not read. If the maker releases one, it will appear on the batch page.
How should I store Femicore?
The label says store in a cool, dry place and keep it out of the reach of children. Avoid a bathroom cabinet or a sunny windowsill.
What if my bottle has a different lot code?
It is not necessarily wrong, because stock rotates. Call the order desk on +1 (302) 200-3480 with your order ID and the code to confirm.
Is Femicore tested by a third party?
No third-party test result is published. This desk holds a certificate reference and has not read the report behind it.
Our view
Our view is that a lot code is worth ten seconds and no more. Check the base, compare the code, and call if it looks odd. It helps tracing, and it is honest about what it is not.
Storage is where you have real control. The label asks for a cool, dry place, and the live strains inside make that more than boilerplate. Keep the bottle closed, away from sun and steam, and keep the packing slip until day 60 has passed. The finished capsule has never been tested in a clinical trial, so be sensible about expectations. This page is not medical advice.
