The Creatine Gummy Testing Scandal:
What Independent Lab Reports Reveal

The creatine gummy market hit $285 million in 2025. It's projected to double by 2028. Influencers promote them. Gyms stock them. TikTok loves them.

There's just one problem: nearly half of them don't contain what the label says.

Over the past two years, independent labs — SuppCo, NOW Foods, Eurofins, and journalists at WIRED magazine — have tested the most popular creatine gummy brands. The results aren't just disappointing. They're a scandal.

The Numbers: 46% Fail Rate

When you aggregate the publicly available independent lab data, the picture is stark. Across all tested creatine gummy brands, 46% failed to meet their label claim for creatine content. Not "slightly under." Some contained trace amounts. Others contained nothing at all.

To be clear: these aren't tests run by competitors trying to make each other look bad. These are independent, third-party laboratory analyses — the same kind the FDA would use. Some were commissioned by supplement watchdog organizations. One was published in WIRED magazine. The labs involved (Eurofins, for example) are ISO 17025 accredited. This is real data.

Brand-by-Brand: What the Labs Found

Let's get specific. Here's what independent testing revealed about the most popular creatine gummy brands on the market:

Happyummmm: 0.1% of Label Claim

Happyummmm claims 5g of creatine per serving on its label. SuppCo sent their gummies to an independent laboratory. The result: 0.005g of creatine detected. That's 0.1% of the label claim. For every dollar you spend, you're getting one-thousandth of the creatine you paid for.

To put this in context: you'd need to eat 1,000 servings of Happyummmm gummies to get the same amount of creatine in a single serving of properly dosed product. At their retail price, that's over $800 worth of gummies to get 5g of creatine once.

Ecowise: Zero Creatine Detected

WIRED magazine's 2020 investigation, titled "The Supplement Industry's Biggest Scam," sent multiple creatine gummy brands to independent labs. Ecowise was one of them. The lab result: 0g of detectable creatine. Nothing. The gummies were, by any scientific measurement, candy with a supplement label.

DeathBites: Multiple Test Failures

DeathBites claims 5g of creatine per serving. Independent testing by SuppCo, and separately by fitness researcher James Smith through Eurofins laboratory, found the product consistently fell below its label claim. DeathBites has appeared in multiple independent analyses, and has failed to meet its stated dose in each one.

Create: Passed Potency, But Flagged for Degradation

Not every result is a clear-cut fail. Create's creatine gummies claimed 4.5g per serving. NOW Foods' 2025 independent analysis found 4.59g — technically a pass on potency. But the analysis also flagged elevated creatinine levels.

Why does that matter? Creatinine is a degradation byproduct of creatine. When creatine breaks down (from heat, moisture, or improper storage), it converts to creatinine — a compound your body can't use for the same purpose. High creatinine in a product that "passed" for creatine content could mean the active ingredient is degrading between manufacture and consumption.

Here's a Summary of Every Failure

*Create passed potency testing but was flagged for elevated creatinine levels (a degradation marker) in NOW Foods' analysis.

The Science: Why Creatine Degrades in Gummy Form

This isn't just a quality control problem. There's a fundamental chemistry challenge with putting creatine into gummy form — and most brands either don't understand it or don't care.

Creatine monohydrate is stable as a dry powder. But gummies contain moisture. They're cooked at high temperatures during manufacturing. And they're stored in warm supply chains, sometimes for months.

Here's what happens:

• Heat exposure during manufacturing: Gummy production involves heating ingredients to 160-180°F. Creatine begins converting to creatinine (its useless byproduct) at elevated temperatures, especially in the presence of moisture and acidic ingredients like citric acid.
• Moisture in the gummy matrix: Gummies are ~15-20% water by weight. Creatine monohydrate in a wet environment degrades faster than in powder form. Over weeks of shelf life, the creatine content drops.
• Creatinine conversion: The degradation product is creatinine — which has the same name root but does nothing for muscle performance. A basic potency test might not distinguish between the two unless the lab specifically tests for both (HPLC analysis does; cheaper tests may not).

This is why NOW Foods' flagging of creatinine in Create's product matters. The creatine was there at manufacture, but may have already started degrading by the time it was tested — and will degrade further before you eat it.

The Math Problem Nobody Talks About

There's an even simpler red flag that most consumers miss. It's arithmetic.

A typical gummy weighs about 4 grams. That's total weight — the gummy base (gelatin or pectin), sweeteners, flavoring, coloring, and the active ingredient combined. If a brand claims 5g of creatine per serving of 2 gummies, they're claiming the active ingredient weighs more than the entire gummy.

This is why honest creatine gummies require 4-5 gummies per serving, not 2. There simply isn't enough physical space in a small gummy to pack 2.5g of creatine alongside everything else. When a brand claims otherwise, they're either using a novel delivery method they should be patenting — or they're lying. The lab results suggest the latter.

What to Look for When Buying Creatine Gummies

We're not saying all creatine gummies are bad. But the data shows nearly half of them are. Here's how to protect yourself:

1. Demand Third-Party Certificates of Analysis (COAs)

A Certificate of Analysis is a document from an independent lab confirming what's actually in the product. If a brand doesn't publish their COAs — or can't produce one when asked — that's a major red flag. Look for labs that are ISO 17025 accredited (like Eurofins or Beaconpoint). In-house testing doesn't count.

2. Check the Serving Size Math

Look at the nutrition label. How many gummies per serving? What's the total serving weight? If a brand claims 5g of creatine in a serving that weighs less than 5g total, something is wrong. Creatine monohydrate is a bulky ingredient. You need volume to deliver dose.

3. Ask About Creatinine vs. Creatine Testing

Standard potency testing measures total creatine-related compounds. HPLC (High-Performance Liquid Chromatography) testing can distinguish between creatine monohydrate (the active compound) and creatinine (the degradation byproduct). If a brand only talks about "creatine content" without specifying the test method, they may be counting degraded product as active ingredient.

4. Look at Price Per Verified Gram

A cheap creatine gummy isn't cheap if it contains zero creatine. Ecowise was one of the more affordable options at $0.67/serving — but the cost per actual gram of creatine was infinite, because there was none. Calculate the real cost based on independently verified creatine content, not label claims.

5. Check Batch-Level Transparency

One test result doesn't guarantee every batch is consistent. The gold standard is brands that test every production batch and publish results for each one. Annual testing or "periodic" testing leaves gaps where formulation or manufacturing issues could go undetected.

Why This Matters

Creatine monohydrate is the most studied sports supplement in history. Over 700 peer-reviewed studies support its efficacy for muscle strength, power output, and cognitive performance. The clinical dose used in most studies is 3-5g per day.

But none of that matters if the product you're taking doesn't actually contain creatine. You're not getting the benefits. You're not loading your muscles. You're eating candy at supplement prices.

The creatine gummy market exists because people want convenience. That's legitimate — compliance with powder can be low (studies show around 60% daily adherence vs. 90%+ for gummies). But convenience without efficacy is just a waste of money.

Consumers deserve to know what they're paying for. The data is public. The lab results exist. The 46% failure rate is documented. The question is whether brands will respond with transparency — or hope nobody notices.
