Creatine Gummies Failed Lab Tests — Here's What Actually Works (2026)

The 2025 lab results that exposed the gummy problem

In 2025, supplement testing company SuppCo purchased six of the best-selling creatine gummy brands on Amazon and sent them to an ISO 17025-accredited laboratory for independent potency testing. The results became one of the year's most-discussed supplement industry stories.

Of the six brands tested, only two delivered creatine content within an acceptable range of their label claims. Two brands contained effectively zero detectable creatine. The most striking result came from a product claiming 5 grams of creatine per serving: actual creatine content was 0.005 grams, one-thousandth of what the label stated. The consumer was paying for creatine and receiving sugar.

Separately, NOW Foods, one of the largest and most established supplement manufacturers in the United States, conducted its own internal testing program on 12 creatine gummy products. Five of the twelve were significantly underdosed, and several contained elevated levels of creatinine (a degradation byproduct of creatine), indicating that the creatine had broken down during the manufacturing process.

Fitness content creator James Smith independently tested the creatine gummies he had been personally endorsing: the brand Ovrload, which claimed 1.5 grams per gummy. The lab result came back at 0.0849 grams, 5.7% of label claim. The brand suspended all sales following the disclosure.

Law firms have initiated class-action lawsuit investigations against multiple creatine gummy brands, including Njord and Astro Labs, based on the lab testing results.

Why gummies fail and powders do not

The failure rate is not random. There is a specific manufacturing reason why creatine gummies are prone to potency problems while creatine powders consistently pass testing.

Creatine monohydrate is stable as a dry powder at room temperature. When mixed into a gummy base, it encounters two enemies: heat and moisture. Gummy manufacturing involves heating ingredients to temperatures that can exceed 70°C (158°F) to create the gel matrix. At these temperatures, in the presence of water and acidic ingredients (citric acid is common in flavored gummies), creatine can undergo cyclization, converting from creatine into creatinine, its metabolically inactive breakdown product. The creatine is physically present during production but chemically degrades before the gummy reaches the consumer.

The NOW Foods testing specifically documented elevated creatinine levels in gummy products, confirming that this degradation mechanism was occurring in commercially available products. This is not a theoretical risk, it is a measured, documented phenomenon.

Powders bypass this problem entirely. Creatine monohydrate powder is micronized and packaged with no heating step, no water exposure, and no acidic flavoring agents to catalyze cyclization. The compound stays chemically identical from manufacture to consumption. This is why every powder tested in 2025 met label claims while the majority of gummies failed, the failure mode is inherent to the gummy manufacturing process, not to creatine itself. We cover the full chemistry of why gummies degrade, and how the format could theoretically be fixed, in our dedicated are creatine gummies effective analysis.

Some brands have attempted to address the gummy stability problem by using creatine hydrochloride (HCl) instead of monohydrate, arguing that HCl is more heat-stable. This may reduce but does not eliminate the degradation issue, and the clinical evidence base for creatine HCl is significantly smaller than for monohydrate. The overwhelming majority of the 500+ published creatine trials used monohydrate. Switching to a different form to make gummies work introduces a new variable while solving only part of the original problem.

How to verify your creatine product (any form)

Whether you use powder, capsules, or gummies, the verification process is the same:

1. Check for a batch-matched certificate of analysis

The COA should include creatine content per serving (measured by HPLC), heavy metal testing, microbial testing, and a batch or lot number that matches the number on your product packaging. If the brand does not offer batch-matched COAs, you have no way to confirm that your specific container was tested.

2. Look for third-party testing, not just in-house QC

In-house quality control is an essential part of manufacturing, but it is not a substitute for independent verification. When the manufacturer tests its own product, there is an inherent conflict of interest: a failed result costs the company money in raw materials, production time, and potential product recalls. This does not mean in-house testing is always dishonest, but it means the incentive structure does not favor transparency when a batch falls short.

Third-party testing by an independent ISO 17025-accredited laboratory eliminates this conflict. The laboratory has no financial interest in whether the product passes or fails, and its accreditation is at risk if it produces inaccurate results. When evaluating a COA, look for the laboratory name, street address, and accreditation number. You can verify the accreditation by searching the database of the relevant accreditation body (A2LA, ANAB, or PJLA in the United States). If the COA does not name the laboratory, or the named laboratory does not appear in any accreditation database, the document has not been independently verified and should be treated accordingly.

3. Check for creatinine levels (degradation marker)

This is the test most consumers have never heard of and most gummy brands hope you do not ask about. Creatinine is the degradation product of creatine. A finished product with high creatinine relative to creatine indicates that the compound broke down during manufacturing, storage, or both. A good COA will include a creatinine assay alongside the creatine potency result. If creatinine is elevated, the effective creatine dose is lower than what the label states, regardless of what the creatine line on the COA shows.

The 60-second gummy audit: what to check before you buy

If you are going to buy creatine gummies despite the testing record, run this checklist first. It takes about a minute and separates the brands that solved the manufacturing problem from the ones hoping you will not ask.

Ask for the finished-product COA, not the raw material COA. This is the single most important question. Many gummy brands can show you a certificate proving the creatine powder was pure before it went into the gummy. That document is worthless for your purposes, the degradation happens during cooking, after that test. Ask specifically: "Do you have a certificate of analysis for the finished gummy, tested after manufacturing?" If the answer is vague, or they send you a raw material COA, you have your answer.

Check for a creatinine number. A finished-gummy COA that includes both creatine and creatinine is the gold standard, because creatinine is the degradation marker. If creatinine is high relative to creatine, the product broke down regardless of what the label claims. Most gummy brands do not test for creatinine because they do not want to know. A brand that volunteers this number is signaling genuine confidence.

Match the batch. The lot number on the COA must match the lot number on the jar you are about to buy. A COA from a different batch tells you nothing about your specific product, because gummy degradation varies from production run to production run depending on cooking temperature and time.

Confirm the lab is named and accredited. The COA should name an ISO 17025-accredited laboratory with a real address, not an anonymous PDF or a screenshot. You can verify accreditation through the A2LA, ANAB, or PJLA databases.

Do the math on cost per verified gram. Take the price, divide by the number of servings, then divide by the verified creatine content per serving (from the COA, not the label). If the brand cannot give you a verified content number, you cannot calculate this, which is itself the answer.

If a gummy brand passes all five checks, it is a legitimate product and the convenience may be worth the premium to you. If it fails even one, and most of the 2025-tested brands failed several, the convenience is irrelevant, because you are not reliably receiving creatine.

What to do if you already bought failing gummies

If you have been taking a creatine gummy that appears on the failed-testing lists, or one whose brand cannot produce a batch-matched finished-product COA, here is the practical path forward. First, you have not harmed yourself: an underdosed or empty creatine gummy is a waste of money, not a safety risk, since the problem is absence of the active ingredient rather than contamination. Second, if you purchased recently, several of the implicated brands are subject to class-action investigations, and you may be eligible for a refund; keep your order confirmation. Third, switch to a verified powder or capsule and give it three to four weeks to reach full muscle saturation, if the gummy you were taking contained little or no creatine, you may notice benefits from a real product that you did not get before. Any strength or recovery progress you made while taking the empty gummy came from your training, and that progress is real; it simply was not coming from the supplement.

Which form should you choose?

The short version: powder is the most reliable format by every measure that matters: label accuracy (100% of powders passed 2025 testing), cost per verified gram, chemical stability, and depth of clinical evidence. Capsules are a convenient middle ground that deliver verified doses without the heat-and-moisture degradation risk of gummies. Gummies are the most convenient but the least reliable, and they carry the highest cost per verified gram even when they pass testing. For a detailed form-by-form breakdown with the full comparison table, pricing math, and results data, see our creatine gummies vs powder comparison and our creatine pills vs powder guide.

The cost of an underdosed gummy

The economics become stark when adjusted for verified content. A $35 gummy product claiming 5 grams per serving but delivering only 0.5 grams works out to roughly $2.33 per verified gram of creatine, compared to about $0.03 per verified gram for powder. At the extreme end, the product that tested at 0.005 grams versus 5 grams claimed was effectively delivering creatine at $233 per gram. You are not paying a convenience premium at that point; you are paying for sugar. For the full pricing analysis across formats, see our best creatine supplements comparison.

Why the gummy failures hit new users hardest

The demographic adopting creatine has shifted well beyond the gym: women in their 30s to 50s, older adults, and first-time supplement users are now a large part of the market, often taking creatine for cognitive and healthy-aging reasons rather than training performance. The gummy format was especially appealing to these newer users because it felt approachable, more like a daily vitamin than a bodybuilding powder. That is exactly why the testing failures are so damaging here: many of these users were taking creatine at lower doses (3 grams or less) for subtle cognitive benefits, and a gummy delivering a fraction of an already-low dose may have provided no physiological effect at all, with no obvious way for a new user to detect the shortfall. If you are new to creatine: and particularly if you are a woman considering it for brain, bone, or perimenopause support: our creatine for women guide covers the dosing, forms, and evidence specific to that use case.

What should the industry do?

The gummy problem is not unsolvable. It requires three things that responsible manufacturers should be willing to invest in: production process validation with creatine-specific stability testing during the gummy cooking process, finished-product HPLC assays for every batch (not just raw material testing), and transparent publication of results including both creatine and creatinine values so consumers can evaluate degradation. Brands that make this investment can legitimately differentiate themselves in a market where trust has been broken. Brands that continue to sell underdosed gummies without testing documentation are making a bet that consumers will not check, a bet that became significantly riskier after the 2025 testing results went public and class-action lawyers got involved.

For consumers, the practical advice is straightforward: do not buy any creatine product: gummy, powder, or capsule, without a batch-matched certificate of analysis that includes both creatine content and creatinine content from a named, ISO 17025-accredited laboratory. This standard eliminates most of the risk in the category regardless of form factor. For our own product recommendations based on verified testing, see our our ranked creatine comparison comparison.

The hair loss question (because it always comes up)

The most common concern that prevents potential creatine users from starting, more than cost, taste, or bloating, is hair loss. This concern originates from a single 2009 study in rugby players that found a transient increase in DHT (a hormone linked to pattern baldness) during a creatine loading phase. That study has never been replicated, and the first randomized controlled trial to directly measure both DHT levels and hair follicle health during creatine supplementation (Lak et al., 2025, 45 males, 12 weeks, 5 g/day) found zero significant differences between creatine and placebo in either outcome.

If hair loss concern is the reason you have been choosing gummies over powder, or avoiding creatine entirely, the evidence does not support that concern. For a full analysis of every study on creatine and hair, see our does creatine cause hair loss deep dive.

The bloating question (the other common barrier)

Creatine draws water into muscle cells, which can temporarily increase body weight by 1 to 2 kg during the first week, particularly if a loading phase (20 g/day for 5 to 7 days) is used. This is intramuscular water retention, not fat gain and not subcutaneous bloating. Skipping the loading phase and starting at 3 to 5 g/day eliminates the initial weight spike for most people, with full muscle saturation reached in 3 to 4 weeks instead of 1 week. For people sensitive to water retention, particularly women tracking scale weight during a fitness program, the slow-start approach is almost always the better choice. For more detail, see our creatine bloating guide.

Why YourHealthier Creatine Hydration Powder

Our Creatine Hydration Powder delivers 5 grams of creatine monohydrate per serving — the exact dose used in the Lak 2025 RCT and recommended by the International Society of Sports Nutrition. It is third-party tested at an ISO 17025-accredited laboratory for every batch, with certificates of analysis published on our Lab Results page. Every powder batch has met label claims. Because powder manufacturing involves no heat or moisture exposure, creatine degradation into creatinine is not a risk factor for this format — unlike gummies, which require specific creatinine assays to verify stability.

Frequently Asked Questions

Are creatine gummies a scam?

To be clear, this question is about whether you get what you pay for, not about physical safety, an underdosed gummy is a waste of money, not a health hazard. Not categorically a scam, but the word implies intent, and what the 2025 data shows may be worse: negligence. Some of these brands may not even know their products are underdosed because they never tested the finished product, they relied on raw material COAs and assumed the creatine survived the gummy cooking process intact. That assumption was wrong in two-thirds of the tested products. Whether the cause was deliberate deception, manufacturing ignorance, or cost-cutting, the result for the consumer is the same: a product that does not contain what the label states, purchased at a premium price, with no way to discover the shortfall through personal experience because creatine's effects are subtle and gradual. The term "scam" may or may not be legally accurate. The term "underdosed" is analytically confirmed. Until a gummy brand can produce a current, batch-matched COA showing HPLC-verified creatine content per serving alongside a creatinine assay confirming low degradation, from a named independent laboratory, powder remains the format with the most reliable potency guarantee across the entire category.

If a creatine gummy brand shows me a COA, can I trust it?

Only if it is the right kind of COA. The critical distinction is raw material versus finished product. Many gummy brands show a certificate proving the creatine powder was pure before it was cooked into the gummy: but degradation happens during cooking, after that test, so a raw material COA tells you nothing about the gummy you are buying. Ask specifically for a finished-product COA, tested after manufacturing, with a batch number matching your jar, and ideally a creatinine reading alongside the creatine number. If they can only produce a raw material certificate, treat it as if they have no COA for the finished product, because functionally, they do not.

How do I know my creatine powder is not fake?

Apply the same verification standard used for any dietary supplement: check for a batch-matched certificate of analysis from a named, ISO 17025-accredited laboratory using HPLC quantification. The COA should include creatine content per serving (which should match the label claim within a reasonable margin, typically plus or minus 10%), creatinine content (the degradation marker: elevated creatinine relative to creatine indicates breakdown during manufacturing or storage), heavy metal panel (lead, arsenic, mercury, cadmium at minimum), and microbial testing (total aerobic count, yeast, mold, pathogens). The batch number on the COA should match the lot number on your container. If there is no lot number on your container, that is itself a quality signal, cGMP regulations require lot identification for traceability. Creapure, a branded creatine monohydrate manufactured in Germany by AlzChem using a proprietary synthesis process, is one of the most widely recognized raw material sources with documented purity standards and an extensive testing history. Other reputable manufacturers exist, but Creapure provides an additional layer of upstream traceability that generic Chinese-sourced creatine typically does not.

Does the dose even matter if the gummy is underdosed?

This is the core problem the testing exposed. The clinical dose of creatine is 3 to 5 grams per day, but that assumes the product actually contains what it claims. A gummy labeled 5 grams that delivers 0.5 grams is not a "low-dose" product; it is an underdosed one, and no amount of taking more gummies fixes a brand's manufacturing failure predictably, because the shortfall varies batch to batch. Get the verified content right first, via a finished-product COA, then worry about hitting the 3-to-5-gram target. For how much creatine to take and whether to load, see our creatine dosage guide.

How could I have been taking a gummy for months and not noticed it was underdosed?

Because creatine's effects are subtle, gradual, and easy to attribute to other things. Unlike caffeine, creatine does not produce a same-day sensation, its benefits to strength and recovery build over weeks and are easily credited to your training rather than the supplement. A person taking an empty gummy while training hard still gets stronger from the training, and naturally assumes the gummy is helping. This is exactly why third-party testing matters more for creatine than for stimulants: your subjective experience genuinely cannot distinguish a working product from an empty one. The only reliable signal is a finished-product lab test.

Does creatine cause hair loss?

Based on current evidence, no. The first and only randomized controlled trial designed to directly measure both DHT levels and hair follicle health during creatine supplementation (Lak et al., 2025, 45 resistance-trained males, 12 weeks, 5 g/day) found zero significant differences between creatine and placebo in either hormone levels or hair density measurements. The original concern traces to a single 2009 study in South African rugby players that found a transient increase in dihydrotestosterone (DHT) during a one-week creatine loading phase at 25 g/day. That study did not measure actual hair loss, the DHT elevation was within normal physiological range, and no subsequent study has replicated the finding. The International Society of Sports Nutrition has specifically addressed this concern, concluding that the available evidence does not support a causal relationship between creatine supplementation and hair loss (Antonio et al., 2021). For the complete evidence review including every relevant study, see our creatine and hair loss article.
