Are Creatine Gummies Legit? How to Tell If Yours Actually Contains Creatine

By the middle of 2025, three independent testing bodies had quietly destroyed the credibility of the creatine gummy industry. NOW Foods tested 13 brands and almost half failed. SuppCo's ISO 17025-accredited lab tested six gummies and found four contained virtually no creatine. A separate UK-led independent test of nine brands found five had less than 0.1 grams per serving. If you're taking creatine gummies, there's roughly a one-in-two chance you're chewing flavoured sugar.

Creatine is the most evidence-backed supplement on the shelf. There are more than a thousand peer-reviewed studies on creatine monohydrate, and the International Society of Sports Nutrition's official position is unambiguous: it works for strength, muscle, recovery, and even cognition. So when the gummy format took off in 2023 and 2024, the surge in demand made sense.

What didn't make sense was the testing data that came out in 2025.

This article walks through what those independent tests actually found, the chemistry that explains why so many gummies fail, the exact steps any honest brand should be able to support, and a seven-question check you can run on your current product right now.

The 2025 creatine gummy testing scandal, summarised in one paragraph

In 2025, three independent organisations tested creatine gummies and reached the same conclusion: roughly half of the products on the market do not contain the amount of creatine they claim. NOW Foods found 46% of brands failed. SuppCo Tested found four of six brands contained virtually zero creatine. James Smith's independently funded UK test of nine brands found five had less than 0.1 grams per serving. The format itself, not just the brands, is the problem.

The pattern is consistent enough that any rational consumer should treat the gummy format with suspicion until a specific brand has proven otherwise. Not "all gummies are scams" — some are excellent — but "every gummy buyer needs to verify before they trust."

Why creatine gummies fail (the chemistry no one explains)

Creatine monohydrate is chemically stable as a dry powder. The moment it comes into contact with water it begins to break down into creatinine — an inert metabolite. Gummies are made with water-based pectin or gelatin bases, so any creatine added during manufacturing has hours of exposure to water and heat before the gummy sets. Without specialised stabilisation processes, most of the creatine in the formula is already creatinine before the product reaches the shelf.

How creatine turns into creatinine in water

Creatine in solid form sits stable for years. Dissolved in water at room temperature, it begins to decompose within minutes. At 70 °C — a typical gummy-cooking temperature — the rate of conversion accelerates dramatically. The reaction is irreversible: once creatine has become creatinine, it cannot be converted back inside the gummy or inside your body.

Creatinine itself is harmless. Your body produces it constantly as a normal product of muscle metabolism, and your kidneys clear it through urine. But it does nothing for your performance, your strength, your cognitive function, or your recovery. It is — for the purposes of a creatine supplement — inert.

Why this is mostly a gummy problem, not a powder problem

SuppCo Tested ran the same protocol on five popular creatine powders alongside the six gummies. Every powder passed. Purity ranged from 98% to 101% of the labelled creatine content. Creatinine — the breakdown product — stayed under 50 parts per million in every case. Heavy metals: clean.

The reason is straightforward. Powder is dry. There's no water for the creatine to react with until you add it to your shaker bottle and drink it within a few minutes. The chemistry stays stable from manufacturing to your muscles.

This is the structural disadvantage of the gummy format — and the reason a credible gummy brand needs a chemistry-aware manufacturing process and proof, not marketing.

Brand-by-brand: every creatine gummy publicly tested in 2025

We've consolidated all three independent test reports below. This is the first article on the internet to present them in one place. Brand names are reported as they appeared in the original test reports — citations underneath link to the primary sources.

Which brands failed

Across the three independent tests, the following brands failed at least one test: Astro Labs, Beast Bites, Con-Cret, Greabby, Njord, DivinusLabs, EcoWise, Happyummmm, Vidabotan, Overload, Unique Physique, "MNT" (no E), Gains Nutrition, and Push Gummies (both Apple and Strawberry variants). Njord is currently the subject of an active class action lawsuit in the United States over claims that the product contained no creatine despite a 5-gram-per-serving label. The lawsuit listing provides the case status and a means to register interest.

Which brands passed

Brands that met or exceeded their label claim in at least one test: Bear Balanced, Bod, Effective Nutra, Iron Labs Nutrition, Peach Perfect, Zhou, Force Factor, Create (in SuppCo and Smith tests), My Vitamins, No Nutrition, and Well Boost. Passing a test does not guarantee that every future batch will pass — which is where Certificates of Analysis come in. More on that in the verification section.

Why one test passes a brand and another fails it

The most useful data point in the table above is Create. SuppCo's June 2025 test found Create's watermelon gummy delivered 4.59 g per serving against a 4.5 g label claim — a clean pass. NOW Foods' later test put Create in the failed cohort. Both labs are reputable. So which is right?

Both. They tested different batches. And that is the point of the exercise.

Manufacturing variance is real, especially for a format as chemically demanding as creatine gummies. A brand that gets one lot right may get the next lot wrong if their stabilisation process isn't robust enough to handle temperature variation, ingredient sourcing differences, or production scaling. The lesson is not that lab tests are unreliable — they are very reliable, when accredited and method-appropriate. The lesson is that brand-level reputation is not enough. Batch-level verification is.

A brand that has passed one independent test should produce a Certificate of Analysis for the specific batch you have in your hand. If they cannot, the historical pass tells you about the lot tested by the lab — not about your bottle.

How to verify your creatine gummy actually contains creatine

A legitimate creatine gummy brand should be able to give you a Certificate of Analysis tied to the exact batch number on your jar. The COA should come from an ISO 17025-accredited lab capable of testing the gummy format specifically. If the brand cannot produce a batch-matched COA within 48 hours of being asked, they almost certainly cannot prove what is inside their product.

Here are the four practical steps any buyer can run today.

Step 1 — Demand a Certificate of Analysis (COA) for your batch

A real COA includes the batch number, the manufacturing date, the test methods used (typically HPLC for creatine quantification), the laboratory's name and accreditation status, and the measured values for creatine content, creatinine content, and heavy metals (lead, mercury, cadmium, arsenic). The batch number on the COA should match the batch number printed on the bottle in your hand. If a brand offers a generic "we test everything" page without batch-specific reports, that's marketing, not science.

Step 2 — Check the manufacturing certifications

Manufacturing certifications audit the facility, not the finished product, but they create the conditions for consistent quality. Look for: Good Manufacturing Practice (GMP), BRCGS Global Standard for Food Safety, FSSC 22000, and country-of-origin transparency. In the UK and EU these are food-safety system audits enforced by independent certification bodies. They are not interchangeable with a COA, but they make consistent COAs possible. A brand with both certified manufacturing and batch-level COAs is the gold standard. A brand with neither should be avoided.

Step 3 — Sensory checks (and what they actually tell you)

Real creatine does not fully dissolve into water. In a gummy that contains real creatine, you should be able to see and feel the difference. Look for slight cloudiness or graininess rather than perfectly clear gloss. When you chew, expect a faintly gritty texture — like very fine sand mixed into the matrix. A perfectly clear, glassy, smooth gummy is suspicious for one of two reasons: either there is no creatine in it, or it has been so heavily processed that the original creatine has long since become creatinine. Sensory checks are not proof — but they are a fast first filter.

Picture it side by side: a real creatine gummy looks slightly cloudy, with a faintly grainy, textured surface. A suspect gummy is perfectly clear, smooth and glassy. That visible difference — cloudy and textured versus clear and glossy — is your fast first filter.

Step 4 — Match the testing lab to the supplement format

This is the one most buyers miss. NOW Foods publicly reported that none of the standard third-party labs they vetted were capable of accurately testing the gummy format. The methods used for powder analysis — typically a straightforward HPLC assay — do not always translate cleanly to a complex matrix of sugar, water, pectin, and flavour compounds. A meaningful gummy test requires a lab that has specifically validated its method for the gummy matrix. When you ask a brand for their COA, the right follow-up question is: "Was the lab's method validated for the gummy format specifically?" An honest answer is more revealing than the COA itself.

What "third-party tested" actually means (and what it should mean)

The phrase "third-party tested" appears on most failing brands too. NOW Foods reported that none of the standard third-party laboratories they vetted were able to reliably test the gummy format. Real verification needs three layers: an ISO 17025-accredited lab, a method validated specifically for gummies (not powders), and a batch-by-batch testing protocol. Anything less is marketing language.

"Third-party tested" without those three layers is the supplement industry's equivalent of "natural" on a food label — technically meaningful, almost universally misused. When a brand publishes a current, batch-matched COA from an ISO 17025-accredited lab that has validated its method for the gummy matrix, that is what real third-party testing looks like. When a brand displays a generic certification badge with no document underneath, that is what the words have come to mean to most buyers, but it is not what the words should mean.

Run your current product through the check below. The answers tell you whether your gummy is likely legitimate, likely problematic, or whether you don't have enough information yet to know.

What APMZEE does differently

APMZEE creatine gummies are manufactured to BRCGS Global Standard for Food Safety, FSSC 22000, ISO 9001, and ISO/IEC 27001 — all independently audited every twelve months. The facility is Made in UK certified, with no-heavy-metals testing on the finished product. We publish our certifications openly, and we provide a Certificate of Analysis for the batch you've bought on request, normally returned within 48 hours.

That's the standard we believe the rest of the industry should meet — and the standard the testing scandal in 2025 made unmistakably necessary.

What to do if you've been taking a failed brand

If you've been taking a creatine gummy that has been publicly identified as failing label tests, you have not been receiving the supplement you paid for. Contact the brand for a refund. Document the batch numbers you took, the dates, and the price paid. In the United States, Njord is currently the subject of a class action lawsuit for misrepresentation. In the United Kingdom, you can report the brand to Trading Standards via your local authority, and the Advertising Standards Authority handles misleading product claims.

None of this is meant to make you anxious about previous purchases. Creatinine — the degradation product creatine becomes when it sits in water — is harmless. You haven't been put at risk; you've been overcharged. The point is to make sure your next purchase actually contains what you're paying for.
