Can I trust creatine supplement label claims without a COA?

No regulatory body in the UK verifies supplement label claims before products are sold. Without an independent Certificate of Analysis from a named lab, a label claim is unverified. It may be accurate, but there is no external confirmation.

What does a Certificate of Analysis for a creatine supplement show?

A COA from an independent lab shows the measured creatine monohydrate content of a specific production batch, compared against the label claim. A credible COA names the testing lab, references a specific batch number, and shows the result as a percentage of the stated dose.

What is the difference between third-party and first-party supplement testing?

First-party testing is conducted by the manufacturer itself, with an obvious conflict of interest. Third-party testing is conducted by an independent accredited laboratory with no financial relationship to the brand beyond the test fee. Third-party testing from a named lab such as RSSL or Eurofins is the only form of testing with no incentive to produce a favourable result.

How do I check if a creatine gummy is underdosed?

Check the supplement facts panel for a per-serving creatine monohydrate amount of at least 3g (5g is the researched standard). Then check for a published Certificate of Analysis from a named independent lab showing the lab-measured content matches the label claim within 10%. If no COA is available from a named lab, the claim is unverified.

Are Creatine Gummies Real?

Q: Do Supps gummies contain 5g of creatine per serving?

Yes. Three Supps gummies deliver 5g of creatine monohydrate per serving, confirmed by batch-by-batch independent testing by RSSL and Eurofins. All results are published at suppsgummies.com/pages/verify.

Real creatine gummies have three things in common. None of them are marketing language. All of them are checkable by anyone before they buy.

A published Certificate of Analysis (COA) from an independent, named lab
The COA references a specific production batch, not a generic document
The tested creatine content matches the label claim within a reasonable margin

If a product cannot provide all three, the label claim is unverified.

Why some creatine gummies are underdosed

UK food supplement regulations do not require pre-market verification of label claims. A manufacturer can print "5g creatine" on packaging without any authority testing that claim before the product goes on sale. The responsibility for verifying the claim rests entirely with the brand or the buyer.

There are two common reasons gummies fail to deliver the stated dose:

Manufacturing economics: Creatine monohydrate is a dense compound. Getting 5g of it into three gummies that taste acceptable requires more active ingredient per unit than cheaper formulations. Some manufacturers reduce the dose to cut cost, often without making this prominent on packaging.
Labelling ambiguity: Some products list creatine content per gummy rather than per serving, or use compound ingredient names that obscure how much active creatine monohydrate is present. "Creatine blend" on a label should prompt further scrutiny.

How to spot an underdosed gummy

Check these four things on any creatine gummy:

The supplement facts panel: It should state "creatine monohydrate" and show a per-serving amount of at least 3g, with 5g being the research-backed standard dose. Check whether the serving size is 1 gummy or 3; the per-gummy figure can look more modest than the full serving dose.
The Certificate of Analysis: Does the lab-measured creatine content match the label? A credible COA shows the result as a percentage of the label claim and will flag a shortfall clearly. Any result below 90% of the label claim is a significant discrepancy.
The lab name: The testing lab should be named and independently operating. "Tested in our facility" is not third-party testing. RSSL, Eurofins, and Informed Sport are examples of credible independent labs used in the UK market.
The batch reference: The COA should include a batch number that corresponds to a specific production run, and that number should match (or be traceable to) what appears on your product packaging. A COA without a batch reference was likely run once and applied broadly.

What "third-party tested" actually means

The phrase is used loosely. There are meaningful distinctions:

Type of testing	Who conducts it	Independence
First-party (in-house)	The manufacturer	None. Obvious conflict of interest.
Second-party (contracted)	A lab contracted and paid by the brand	Partial. The lab has no incentive to fail a client.
Third-party (independent)	An accredited lab with no commercial relationship beyond the test fee	Full. No financial relationship that could influence the result.

True third-party testing means the brand cannot influence the outcome. The lab produces its result and the brand publishes it, including if the result is unflattering.

How Supps does it

Every Supps production batch is tested by both RSSL and Eurofins, independently commissioned. The Certificate of Analysis for each batch is published at suppsgummies.com/pages/verify, linked to the batch number on the packaging. The tests confirm creatine monohydrate content against the 5g-per-serving label claim.

You can check the batch number on your pack against the published results. That is the purpose of the page.

Frequently asked questions

Can I trust supplement label claims without a COA?

No regulatory body in the UK verifies supplement label claims before products are sold. Without an independent COA, a label claim is unverified. It may be accurate; there is no external confirmation that it is.

What is a Certificate of Analysis?

A COA is a document produced by a testing laboratory that states the measured content of a product sample. For a creatine supplement, it should confirm the creatine monohydrate content measured against the stated dose. The COA is only meaningful if it comes from an independent, named lab and references a specific batch.

Do Supps gummies contain 5g of creatine per serving?

Yes. Three gummies deliver 5g of creatine monohydrate, confirmed in the batch-by-batch COA published at /pages/verify.

How often does Supps test its products?

Every production batch is tested before and after manufacture. Both RSSL and Eurofins run independent tests on each batch.

Where can I see the Supps lab results?

All results are published at suppsgummies.com/pages/verify. Each COA is linked to a batch number that appears on the product packaging.

What should I do if my creatine gummy does not have a published COA?

Contact the manufacturer and ask for the Certificate of Analysis for your specific batch. If they cannot provide one from a named independent lab, the label claim is unverified. The absence of a COA is not proof of underdosing, but it is a reason not to take the label at face value.
