What Arnold Schwarzenegger said about creatine gummies
The seven-time Mr. Olympia told his newsletter readers that most creatine gummies contain almost no creatine. Here is the lab round behind that warning, product by product.

The short version. In his Arnold’s Pump Club newsletter on October 28, 2025, Arnold Schwarzenegger warned that lab tests found most creatine gummies contained almost no creatine, and recommended tested creatine monohydrate powder. The test he drew on was SuppCo’s 2025 round: 4 of 6 gummies failed, and all 5 powders passed. The two gummies that passed were Create (4.59 g measured vs 4.5 g label) and Force Factor (6.3 g vs 5 g). So his warning is right about the category, and incomplete about individual brands.
What Arnold said
The newsletter’s own heading was “The Bitter Truth About Creatine Gummies.” Fitness Volt reported the piece. As reported, he said independent tests found that most contained almost no creatine, and some none. He said a good gummy is possible to make but that the format isn’t reliable yet, and he pointed readers to creatine monohydrate powder with third-party verification such as NSF Certified for Sport or Informed Sport. The newsletter passages quoted by Fitness Volt do not name brands.

The test behind the headline
SuppCo bought 11 creatine products from Amazon — 6 gummies and 5 powders — and sent them to an ISO 17025-accredited lab. Our lab tracker lists every row with its source.
| Product | Label claim | Measured | Result |
|---|---|---|---|
| Force Factor creatine gummies | 5 g | 6.3 g | Pass |
| Create creatine gummies (Watermelon) | 4.5 g | 4.59 g | Pass |
| DivinusLabs | 5 g | Trace | Fail |
| Happyummmm | 5 g | 0.005 g | Fail |
| EcoWise | 5 g | None detected | Fail |
| Vidabotan | 5 g | None detected | Fail |
| 5 creatine powders (pooled) | 5 g | 98–101% of claim | Pass |

Is Arnold right?
About the category, yes. SuppCo’s round was not a one-off. Across the three public testing rounds we track (NOW Foods, SuppCo and a July 2025 Eurofins round publicized by James Smith), 16 of 28 gummy tests missed their label claim, while powders passed. Heat and moisture during gummy manufacturing can break creatine down into creatinine.
About every gummy, no. Two products in the very round he relied on delivered their labeled dose. Several brands also carry NSF Certified for Sport on specific flavors. A fairer summary is: most cheap, uncertified gummies are a gamble; a certified gummy with a published passing test is a reasonable choice if you will take a gummy and not a powder.
Caveats on the passes. One sample is one lot. Create also passed the July 2025 Eurofins round, but appears in an earlier NOW Foods round where it did not meet its claim, and two lawsuits have alleged underdosing (one was voluntarily dismissed; neither had a merits judgment in the dockets we checked). Read Is Create legit? and our Create vs Force Factor comparison before buying.
What to do with this
- Cheapest and most reliable: plain creatine monohydrate powder, as Arnold suggests. See gummies vs powder.
- If you will only take a gummy: choose one with NSF Certified for Sport on your exact flavor and a published potency test. See best creatine gummies.
- Avoid unknown marketplace brands with no certification and very low prices.
One of the two gummies that passed. Create measured 4.59 g against a 4.5 g label in SuppCo’s round and lists NSF Certified for Sport flavors. Match your flavor to the NSF listing.
