Renew31 testing and quality: marks, and no certifying body

Six named marks were supplied with this stock and all six are shown on this page, because none is contradicted by the label. 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. No testing house was named, no assay was supplied, no laboratory report arrived and no certificate of analysis reached this desk, so Renew31 is not described as tested or third-party verified anywhere here. No trial on the finished formula was supplied either. The printed label earns credit in four places: the blend is declared in descending order of weight, the total is declared, the dagger convention is correct and an allergen statement is volunteered. It stops short in four more: no extract ratio for any of the 9 botanicals, no weight for Bacillus coagulans, no manufacturer and no third-party mark.

Testing and quality, in under a minute

Read time under a minute
  1. Six named marks were supplied and all six are shown here. 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.
  2. No laboratory, assay or certificate document reached this desk. The certificate reference supplied is R-6641-26-GE, which is a string rather than a report.
  3. No trial on the finished formula was supplied. Every source cited here describes an ingredient, a category or a regulation.
  4. The label earns credit in four places: the ordering rule, the blend total, the dagger convention and a volunteered allergen line.

All six marks, shown

Six named marks were supplied with this stock. Every one is shown here, because none is contradicted by the label, and a mark quietly dropped is an edit a reader cannot check.

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.

That table has three empty columns on purpose. They are what would turn a mark into a claim a reader could follow: who certifies it, under which certificate, and when the audit happened. Not one of the six carries any of the three.

A seal is artwork, not a certificate

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.

What a mark shows

That somebody put a graphic on a page. That much is visible, and this site reproduces it.

What a mark does not show

Who issued it, what it was issued against, and when. None of the three was supplied for any of the six.

What this site therefore says

That the marks were supplied, that all six are shown, and that none of them is evidence about a batch.

The six split into three kinds. Some describe the product: pure, vegetarian, dairy free, gluten free. One describes a commercial promise rather than the formula. One describes a clinician.

The guarantee page tests the money-back mark against the wording supplied with it, and the answer is not clean: a 60-day window and a 30-day use expectation leave a 30-day band. The clinician mark is tested on the about page, which publishes an empty byline slot rather than a borrowed name.

What the label does print, and where it stops

The label earns credit in four places and runs out in four more. Both halves belong on a page about quality.

What the printed label does and does not state about how this product was made and measured.
The itemStatusWhat is actually known
The blend is declared in orderPrinted21 CFR 101.36(c)(2) requires it, and it is the only quantitative information the blend carries. Without it, none of the 9 ceilings on this site could be worked out.
The dagger convention is used correctlyPrinted“Daily Value Not Established” is what the regulation asks for against an ingredient with no Daily Value.
An allergen statement is volunteeredPrinted“No Allergens” is not a format FDA prescribes. An affirmative no-allergens statement is the manufacturer’s own assertion. It is not a declaration format FDA prescribes.
The blend total is declaredPrinted430 mg for all 9 botanicals, which is what “shall be the total weight of all other dietary ingredients contained in the proprietary blend” 21 CFR 101.36 requires.
Extract ratios and standardisationnot publishedNo extract ratio, no marker compound and no standardisation percentage is printed for any of the nine botanicals.
A weight for Bacillus coagulansnot publishedThe panel quantifies it in CFU and in nothing else. 21 CFR 101.36(b)(3)(ii)(A) requires other dietary ingredients to be expressed in metric measures.
A manufacturer or facilitynot publishedNo manufacturer, facility or registration number is named in any supplied material.
A third-party testing marknot publishedNo testing house, no certificate and no third-party seal appears in any material supplied with this stock.

The first four are real. The ordering rule is observed, the blend total is declared, the dagger convention is correct and an allergen statement is volunteered where no such format is required. That last one is the manufacturer’s own assertion rather than a prescribed declaration.

The last four are where a quality page wants figures and finds none. No extract ratio, marker compound or standardisation for any of the nine botanicals. No weight for Bacillus coagulans, which is quantified in cells and nothing else: “These amounts shall be expressed using metric measures in appropriate units.” 21 CFR 101.36 No manufacturer, and no third-party mark.

Why a document matters more on a live-microbial product

The headline ingredient here is a living organism, and the federal sources are unusually direct about what that means for a label.

NCCIH, on what has been found in products of this kind: “Some probiotic products have been reported to contain microorganisms other than those listed on the label.” NCCIH And on who carries the risk: “The risk of harmful effects from probiotics is greater in people with severe illnesses or compromised immune systems.” NCCIH

NIH ODS, on what a label must carry: “Current labeling regulations only require manufacturers to list the total weight of the microorganisms on probiotic products’ Supplement Facts labels” NIH ODS And on why the marketplace is hard to read: “it can be difficult to determine which products offer verifiable health benefits due to the wide variety of probiotic strains and doses found in probiotic products and inconsistent labeling practices” NIH ODS

The two sentences this site carries on every page about this product

“The risk of harmful effects from probiotics is greater in people with severe illnesses or compromised immune systems.” NCCIH

“Some probiotic products have been reported to contain microorganisms other than those listed on the label.” NCCIH

Both travel together, because the second is why the first matters: a product containing something other than what its label says is a different risk to somebody with a compromised immune system. The cautions page

None of that is an allegation about Renew31. It is why a certificate of analysis naming your lot is worth more here than a row of marks, and why this site will not call a reference string a test result. The batch page is what reached this desk, item by item. 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.

Five questions for the order desk

Much of what this page marks as not published is unpublished rather than unknowable, and the desk that handles this product every day can settle several in a minute.

  • Is there a certificate of analysis for lot R-26/GE-6641, and can it be sent?
  • Which laboratory, if any, has tested this formula or this lot?
  • Who certifies each of the six marks, under what certificate number, and when was the last audit?
  • Who manufactures it, in which facility, and under which registration?
  • What is the best-before date on the bottles currently being shipped?

Order desk +1 (302) 200-3480. The hours the order desk keeps are not published. The Monday to Friday, 9:00am - 5:00pm ET window published with this stock belongs to the website desk, which cannot see an order, so this site prints the order number and leaves its opening times blank rather than borrowing somebody else’s working day.

If an answer arrives, it changes this page rather than sitting in an inbox. The batch page lists what would change it, and the website desk at [email protected] takes corrections.

Questions

Renew31 testing and quality: common questions

Is Renew31 third-party tested?
Not published. No third-party mark, no testing house, no certificate and no laboratory report appears in any material supplied with this stock. Third-party tested means an independent laboratory tested the finished product and published a document naming the lot. A mark printed on a carton is artwork; a document naming your lot is evidence. This site has the first and not the second.
Is Renew31 FDA approved?
No dietary supplement is FDA approved, and this one makes no such claim. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease. What FDA does govern here is the label itself, and the label page works the printed panel through against the two regulations that apply to it.
Is Renew31 doctor formulated?
A mark reading that was supplied with this stock, and it is shown on this page with the others. No formulating clinician is named in anything supplied, and no sign-off, date or correspondence came with the physician’s name that did arrive. That name appears nowhere on this site: the about page
Has the finished Renew31 formula been tested?
Not published. 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. Every source cited on this site describes a single named ingredient, a category of products or a labelling regulation.
Who makes Renew31?
Not published. No manufacturer, facility or registration number is named in any supplied material. So this site names no manufacturer, no facility and no country of manufacture, and does not describe the absence of those as evidence of anything either.
