Slim Metrix Testing and Quality: Every Seal Explained Honestly

Written and reviewed by the Slim Metrix Editorial DeskLast updated 7 min read
Quick answer

Slim Metrix prints a Supplement Facts panel, a lot number (SLI-26/GO-6640) and a CoA reference (SLI-6640-26-GO). No lab certificate is public, and no maker is named on the supplied images. Of its 10 seals, three fit the label, one has written terms and six cannot be checked. The “3rd-party tested” checkmark is an unverified brand claim.

Quick view

What quality proof does Slim Metrix publish?

What exists, what is only a reference number, and what has not been published.

Slim Metrix publishes a Supplement Facts panel, ten quality seals, a lot number and a CoA reference number. It does not publish a lab certificate, and the maker's name is not visible on the supplied images.

So the paperwork is partly there. You can read what is in each capsule, but not how much of most ingredients, and not who checked it. This page goes through each piece of evidence and says how much it can carry.

Honest analysis

Are the Slim Metrix comparison graphic checkmarks verified?

Brand graphics are marketing. Here is what each checkmark would need before we could call it confirmed.

Brand graphic comparing Slim Metrix with other brands on five checkmarks
The brand's own graphic comparing Slim Metrix with unnamed “other brands”. Every checkmark is a claim by the brand.

No. The checkmarks in the brand's comparison graphic are claims, not results. We have seen no document that backs any of them, and the “other brands” are never named.

The five comparison checkmarks and what would back them

CheckmarkWhat would prove itStatus
Clinically studied ingredientsTrials on this formula at these dosesIngredients were studied alone, at larger doses
3rd-party testedA lab report naming the lab and the lotNo report published
Allergen freeAn allergen statement or testNo allergen statement on the label images
GMP-certified facilitiesA certificate from a named auditorNo auditor or plant named
Paleo-friendly & gluten-freeA label review or testLabel fits; no test public

“Clinically studied” is the easiest to misread. The ingredients have been studied, but mostly at doses much larger than this capsule can hold. The dose math is on the Slim Metrix ingredients page.

Regulation

Which FDA rules cover Slim Metrix capsules?

Slim Metrix is sold as a dietary supplement, so supplement rules apply, not drug rules. The FDA does not approve supplements before sale (U.S. FDA, Dietary Supplements Q&A). The company that markets a supplement must make sure it is safe and labeled truthfully.

Makers also have to follow the FDA's current Good Manufacturing Practice rules for supplements. Those rules cover clean plants, batch records and checks that each batch matches its label. The FDA can inspect a plant and act after a product is on sale.

  • Required: a safe product, an honest label and GMP records
  • Not required: proof that the product works, or a public lab report
  • For you: the brand's claims have not been evaluated by the FDA

†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. This note goes with every brand claim on this site.

Honest analysis

What Slim Metrix quality details are still missing?

Reference numbers are a starting point. A lab report is the proof.

The biggest gap is a lab report. The brand gives a CoA reference, SLI-6640-26-GO, and a lot number, SLI-26/GO-6640. Those numbers point to a record, but we have not seen the record.

A real certificate of analysis is a lab report for one batch. It lists how much of each ingredient the lab measured, plus tests for heavy metals and microbes. A report from an independent lab counts for more than one from the factory.

Formula quality

Slim Metrix capsules: the shell and the flow agents

The active ingredients get the attention. These four decide how the capsule is made and filled.

The four other ingredients in Slim Metrix, in label order

Other ingredientJob in the capsuleWorth knowing
HypromelloseVegetable capsule shellA plant-cellulose shell, used instead of gelatin.
Microcrystalline celluloseFiller and bulking agentRefined plant fiber that fills out the capsule to a set size.
Magnesium stearateFlow agent (lubricant)Stops powder sticking to filling machines. Used in small amounts.
Silicon dioxideAnti-caking agentKeeps the powder loose so each capsule fills evenly.

This is a standard recipe for a powder-filled capsule. The label lists 0 calories and under 1 g of carbohydrate per capsule, and no sugar, sweetener or dye. The capsule has no taste to mask, so there are no flavors either. Daily-use tips are on the how to take Slim Metrix page.

On delivery

How to check a Slim Metrix bottle when it arrives

Four checks take about two minutes, before your first capsule.

  1. Check the seal

    The seal under the cap should be whole. If it is torn or missing, do not take the capsules. Call the order desk with your order ID.

  2. Find the lot and date

    Lot and best-before are on the base when the bottle shows them. Write the lot down in case you need it later.

  3. Match the panel

    It should read 1 capsule per serving, 30 servings, zinc 5.5 mg, chromium 0.05 mg and a 276 mg proprietary blend.

  4. Look at the capsules

    They should be dry and whole, with no cracks, clumps or odd smell. Remember it comes in a bottle, not a pouch.

Our wish list

What would make Slim Metrix quality easier to trust?

Five steps would move the quality picture from “probably fine” to “shown in public”. None of them would change the formula.

  1. Publish the lab certificate for lot SLI-26/GO-6640, ideally from an independent lab
  2. Name the maker and the plant behind the GMP and FDA-registered facility seals
  3. Print the amount of each ingredient in the 276 mg blend, including EGCG
  4. Name the doctor behind the doctor-formulated seal, or drop the seal
  5. Name the lab behind the “3rd-party tested” checkmark

We will update this page when any of these appear. Until then, the money-back guarantee is the main protection buyers have.

FAQ

Slim Metrix testing and quality questions

Is Slim Metrix third-party tested?

The brand's comparison graphic says so, but no third-party lab report is public. We have a lot number and a CoA reference, not the certificate. Until a report is published, treat the claim as unverified.

Does the FDA-registered facility seal mean the FDA checked Slim Metrix?

No. The seal is about the factory, which is listed with the FDA. A registration is not an inspection result and not an approval. The FDA does not approve dietary supplements before they are sold.

Is Slim Metrix vegetarian?

The capsule shell is hypromellose, a plant-based material, and the label lists no gelatin. The label does not say whether the magnesium stearate comes from plants or animals. No outside group is named as a certifier.

Is Slim Metrix gluten free?

No wheat, barley or rye appears on the label, which fits the gluten-free seal. No test result or certifier is published. People with celiac disease should ask the order desk before buying.

Who manufactures Slim Metrix?

The maker's name is not visible on the product images we were given. Goslimmetrix sells the product but does not make it. We will add the name if the brand publishes it.

What does the Slim Metrix CoA number prove?

On its own, nothing. SLI-6640-26-GO is a reference number tied to lot SLI-26/GO-6640. Proof would be the lab report itself. You can ask the order desk at +1 (562) 523-2626 for a copy.

Why does Slim Metrix contain magnesium stearate and silicon dioxide?

Both help powder flow evenly into capsules during filling. They are common in capsule supplements and are used in small amounts. Neither is an active ingredient.
