Verification
Renew31 batch verify: lot R-26/GE-6641, and what a string is not
Two reference strings were supplied with this stock: lot R-26/GE-6641 and certificate R-6641-26-GE. Both are label values, and no certificate of analysis document reached this desk: no laboratory, no assay, no date, no signature. A lot code proves two narrow things. It shows that two bottles carrying the same code came from one production run, and it tells you which document to ask for. It cannot show what is in the bottle, that anything was tested, or that the organism named on the label is the one inside. Four checks need no equipment: the gummy count, which the panel gives as 30; the calorie line, printed as 4 where the lawful values below 50 are 0, 5, 10; the missing Dietary Fiber line; and the misprint in the Other Ingredients list. The order desk on +1 (302) 200-3480 can be asked for a certificate before you pay.

The batch, in under a minute
Read time under a minute- Two reference strings were supplied: lot R-26/GE-6641 and certificate R-6641-26-GE. Both are label values.
- No certificate of analysis document reached this desk. No laboratory, no assay, no date and no signature.
- A reference string is not a document, so this site does not describe Renew31 as tested or verified anywhere.
- Four checks need no equipment: the gummy count, the calorie line, the missing Dietary Fiber line and the misprint in the Other Ingredients list.
Two reference strings, and what they are
Two values arrived with this stock: a lot reference reading R-26/GE-6641 and a certificate reference reading R-6641-26-GE. Both are strings on a page. Neither is a document.
| The item | As supplied | Status | What is actually known |
|---|---|---|---|
| Lot reference | R-26/GE-6641 | A string supplied with this stock | Supplied as a label value. No document came with it |
| Certificate reference | R-6641-26-GE | A string supplied with this stock | Supplied as a label value. No document came with it |
| A certificate of analysis document | not published | Nothing reached this desk | No file, no scan, no laboratory name, no assay, no date, no signature |
| A laboratory name | not published | Not supplied | No testing house, accreditation or scope of testing was named |
| A public lot lookup | not published | Not supplied | No index, portal or reference number service was named for either string |
| A best-before date | not published | Not in the supplied artwork | No expiry or best-before figure appears in anything supplied here |
The distinction is not pedantry. A lot number identifies a production run. A certificate of analysis is a laboratory’s report on what that run contained. The first is a filing reference, the second is evidence, and only one of the two arrived.
So this site does not describe Renew31 as tested, verified or batch-checked anywhere, and does not print either string as though it settled something. A lot code and a certificate reference were supplied as strings. No document was.
What a certificate of analysis is, and what it would say
A certificate of analysis is a short document with a narrow job: it names a lot and reports what a laboratory measured in it.
What it names
A lot. A document that does not name the lot on your bottle is about somebody else’s bottle.
What it reports
What a named laboratory measured, by which method, on which date, signed.
What it is not
A seal, a roundel, a reference string or a marketing claim. A seal is artwork, not a certificate: no certifying body, certificate number or audit date was supplied for any of the marks shown with this stock.
On this product the measurements that matter are specific. A count of 500 Million CFU would say whether the panel figure was met at the date of testing. An identity test would say whether the organism is the one named. An assay on the 430 mg blend is the only thing that could turn any of the 9 ceilings into amounts.
“Some probiotic products have been reported to contain microorganisms other than those listed on the label.” NCCIH That is not an allegation about this product. It is why a document naming your lot is worth more than a row of marks on a carton, and the testing page sets out what those marks carry.
Renew31, from $49 a bottle. 30 gummies at 1 gummy a day, so a bottle is 30 days.

What a lot code can and cannot prove
The honest version of this page is a two-column answer, and the useful column is the shorter one.
| Side | The claim | Why |
|---|---|---|
| Can prove | That two bottles came from the same run | Two bottles carrying the same lot share a production run, which is useful when something differs between them. |
| Can prove | Which document to ask for | A certificate of analysis names a lot. The lot on your bottle is how you tell whether a document is about the product in your hand. |
| Cannot prove | What is in the bottle | A code is an identifier. It carries no assay, no purity figure and no count. |
| Cannot prove | That anything was tested | A reference string is a filing reference. A lot code and a certificate reference were supplied as strings. No document was. |
| Cannot prove | That the organisms on the label are the ones inside | That is what a laboratory report settles, and none was supplied. NCCIH: “Some probiotic products have been reported to contain microorganisms other than those listed on the label.” NCCIH |
Both halves matter. A buyer who reads a printed lot code as proof of testing has been misled by a convention: codes appear on tested and untested products alike and look identical. A buyer who dismisses the code loses the one thing it is good for.
Two sentences travel with every page on this site about a live-microbial product, and they are the reason a question about a serious illness belongs with a clinician rather than with a desk. NCCIH: “The risk of harmful effects from probiotics is greater in people with severe illnesses or compromised immune systems.” NCCIH And: “Some probiotic products have been reported to contain microorganisms other than those listed on the label.” NCCIH
Four checks that need no equipment
Nothing here depends on a laboratory, a certificate or a desk. All four are printed on the bottle in your hand and can be held against the transcription this site publishes.
| The check | What is printed | Why it matters |
|---|---|---|
| Count the gummies | 30 | The panel says 30 servings of 1 gummy per container. One a day makes the bottle exactly 30 days, and every figure on this site in days rests on that count. |
| Read the calorie line | 4 | Below 50 calories the lawful values are 0, 5, 10. 4 is not one of them, and that is checkable against the printed panel in your hand. |
| Look for a Dietary Fiber line | not published | There is none. Omitting it is lawful only under a gram of fibre, which the calorie figure makes difficult to reconcile. |
| Read the sixth other ingredient | “Critic Acid” | Printed exactly so. It is a misprint of citric acid, and it is reproduced here rather than tidied because a transcription that corrects the label is no longer a transcription. |
The gummy count is the one everything else rests on. One gummy a day and 30 in a bottle, so a bottle is exactly 30 days. That single division is what lets every figure on this site be quoted in days rather than in servings. The other three are the panel checking itself. Below 50 calories the lawful values are 0, 5, 10, so 4 is not among them. A Dietary Fiber line may be omitted only when a serving holds under a gram: “except that if a serving contains less than 1 gram, declaration of dietary fiber is not required” 21 CFR 101.9. And the misprint is reproduced rather than tidied, because a transcription that corrects the label is not a transcription.
The label page works all four through against the regulations they sit under.
What would change this page
Two documents would rewrite most of it, and neither is exotic. Both exist for products that have them.
- A certificate of analysis naming lot R-26/GE-6641, with a laboratory and a date.
- A count and an identity test for Bacillus coagulans at the date of manufacture.
- An assay on the 430 mg blend, which would turn 9 ceilings into amounts.
- A published trial on the finished formula rather than on single ingredients.
- A manufacturer, a facility or a registration number. No manufacturer, facility or registration number is named in any supplied material.
The first is a certificate of analysis naming lot R-26/GE-6641, with a laboratory, a method, a date and a signature. The second is a published trial on the finished formula. No published trial on the finished Renew31 formula was supplied with this stock and none appears in any source this desk opened. Every reference on this site describes a single named ingredient, a category of products, or a labelling regulation. That is a different thing from testing this gummy.
Until one arrives, this page says what it says. If either does, write to [email protected] with the page and the line. The about page is the method, and +1 (302) 200-3480 can be asked for a certificate before you pay.
Ask the order desk for the certificate before you buy
The desk on +1 (302) 200-3480 can be asked for the certificate covering a specific lot. Two bottles is $158 and six is $294.
