Memopryl Batch Verify: Lot Number, Safety Seal and a Genuine-Bottle Check

Written and reviewed by the Memopryl Editorial Desk · Last updated · 7 min read

Quick answerTurn the bottle over. When they are printed, the lot number and best-before date sit on the base. Current stock is listed as lot MEM-26/GO-8833 with CoA reference MEM-8833-26-GO. Both are record numbers only; no lab certificate has been published. Check the seal, the front text and the 60-capsule count, then photograph the back panel.

Where are the lot number and best-before date on Memopryl?

One Memopryl bottle, 60 capsules
The front shows the brand, the three support claims and the 60-capsule count. Batch codes are not on the front, so turn the bottle over to the base.

Check the base of the bottle first. When the maker prints them, the lot number and best-before date appear there in small type.

A phone camera helps. Take a close photo in good light, then zoom in to read each character.

If the base is blank, look around the label seam and under the cap edge. If you still find nothing, call the order desk before you open the bottle.

The codes

What do lot MEM-26/GO-8833 and CoA MEM-8833-26-GO stand for?

The retailer lists current Memopryl stock as lot MEM-26/GO-8833. The matching certificate of analysis (CoA) reference is MEM-8833-26-GO.

A lot number ties a bottle to one production run. It is what a maker uses to trace complaints and pull stock if a recall is needed. No key to the parts of these codes has been shared, so we do not guess what each segment means.

Honest note

Has a lab certificate for Memopryl been published?

No. There is a CoA reference number, but no certificate has been released to buyers. We have seen no lab name, no test date and no results.

That means the public record cannot confirm what each capsule holds or what it was tested for. The Supplement Facts panel was also missing from our files, so every amount is marked "not published" on the Supplement Facts page.

If a certificate is released, we will link it here and move the "Last updated" date forward. Until then, treat the codes as filing numbers.

Step by step

How do you check a genuine Memopryl bottle?

Six checks take about ten minutes. You need the bottle, your order email and a phone with a camera.

  1. Inspect the seal before opening

    Check that the cap is tight and the inner safety seal is whole. A torn, loose or missing seal is a reason to stop and call the order desk.

  2. Read the front label

    The front should read ADVANCED FORMULA, MemoPryl, By NutraVibe, Supports Concentration, Supports Brain Energy, Supports Productivity, 60 CAPSULES and DIETARY SUPPLEMENT.

  3. Find the lot and best-before date

    Turn the bottle over and look at the base. Write down both codes, or take a sharp photo of them.

  4. Photograph the back panel

    Take a clear photo of the Supplement Facts panel on the back. It shows the serving size and amounts that are not published in our files.

  5. Count and compare

    Once open, check that you have capsules, not tablets or loose powder. The bottle should hold 60.

  6. Confirm the seller and call if unsure

    Match your order email to this site or the brand checkout. Call +1 (302) 200-3480 with your order ID and the lot number if anything looks off.

Back panel

Why photograph the Supplement Facts panel?

The back panel is the one part of the bottle we could not see. It should list the serving size, each ingredient amount and the other ingredients.

A clear photo does three jobs. It shows you how many capsules to take. It gives your pharmacist the St. John's wort amount to check against your medicines. It also gives the order desk proof if a bottle ever looks different.

Keep one folder

Take the photo before the label gets worn. Save it next to your order email and a photo of the base, so all three sit in one folder.

Side by side

What does a genuine bottle look like next to a warning sign?

The list below comes from the bottle front and from the claims regulators flag in this category. Hold the bottle and work down the rows.

Read down the list with the bottle in hand. One warning sign is enough to pause and call before your first capsule.

Why it matters

Why does batch checking matter for a brain energy supplement?

Memory and focus products attract bold sellers. In 2019 the FDA warned 17 companies selling more than 58 products with illegal Alzheimer's claims (FDA, Alzheimer's claims, 2019).

A genuine Memopryl bottle makes only three support claims: concentration, brain energy and productivity. A copy may promise far more, or hold something other than what the label says.

Checking the seal, seller and lot is a small habit that lowers that risk. It also matters because St. John's wort interacts with many medicines, as the side effects page explains.

Dates

How should you read the best-before date?

The best-before date applies to a sealed bottle kept as the label directs. After you open it, air and moisture reach the capsules every day.

Keep the cap tight and store the bottle away from heat and steam. Your bottle's own storage line comes first.

General handling for capsules. Follow the storage line printed on your bottle.

Resale listings are harder to trust. Stock may be old, stored in heat or repackaged, and the order desk may not be able to find the order.

FAQ

Memopryl batch verify FAQ

Where do I find the Memopryl lot number?

Look on the base of the bottle, where the lot number and best-before date are usually printed. If you cannot find them, photograph every side and call the order desk.

What lot is current Memopryl stock?

The retailer lists lot MEM-26/GO-8833 and CoA reference MEM-8833-26-GO for current stock. A later batch will carry a different code.

Is there a Memopryl certificate of analysis I can read?

Not yet. A CoA reference number exists, but no lab certificate has been published. We have seen no lab name, test date or result.

My bottle shows a different lot. Is it fake?

Not necessarily. Every batch gets a new code. Call +1 (302) 200-3480 with your order ID and the code, and ask the desk to confirm it.

Why should I photograph the back of the bottle?

The Supplement Facts panel was not in our files. Your photo lets you, your pharmacist and the order desk read the serving size and amounts.

What if the safety seal is broken?

Do not take any capsules from that bottle. Keep it with its packaging, take photos, and call the order desk with your order ID.

Can the website email check my batch?

No. [email protected] cannot see orders or batch records. Batch questions go to the order desk by phone.
