Let me say the conclusion first, because I don’t want the nuance to read as me hedging: creatine monohydrate is a gift. It’s one of the few supplements on the shelf that does roughly what it says, costs almost nothing, and has decades of human trials behind it. If you are consistently doing resistance training, it’s almost a no-brainer.
So this isn’t a takedown of creatine. It’s a look at what happens to a genuinely good molecule when marketing gets hold of it: inflated claims, upcharges for gummies, the citations that don’t say what they are claimed to say. Because the tell of a grift isn’t that the product is worthless. I think often times, there are crumbs of truth to many claims in the wellness industry. It’s that the story around it has drifted from the evidence. And with creatine, the drift is easy to see once you know where to look.
Here’s what I found pulling the claims off three popular creatine brands and checking them against the primary literature.
What the research actually says
Strength and power: solid. This is the part that’s earned. Creatine’s effect on strength, power output, and high-intensity performance is about as well-established as anything in sports nutrition. If a brand says creatine helps you get stronger alongside training, they’re right, and the citations back them up.
Muscle size: real, but smaller than the labels imply… and it’s partly water. This is where the first bit of drift shows up. For years the standard claim has been that creatine adds a kilo-plus of “lean mass.” The problem is how that mass was measured. Most studies used DXA or bioelectrical impedance, which lump muscle and water together as “lean mass.” When researchers measure actual muscle with direct imaging instead (MRI, CT, ultrasound) the extra gain from creatine shrinks to a much smaller value. A 2023 meta-analysis by Burke and colleagues found the added muscle thickness from creatine plus training, over training alone, was in the range of a tenth of a centimeter [1]. A 2025 randomized trial went further: it added a one-week “wash-in” phase with no exercise, and found the creatine group’s apparent lean-mass advantage showed up before anyone had trained which is consistent with creatine pulling water into muscle rather than building it [2].
So: creatine helps you build muscle alongside training, but the size effect is modest, and some of what the scale and the DXA scan call “muscle” is actually just water. That doesn’t make it useless. It makes “build lean muscle” an overstatement of a real thing.
Memory and cognition: promising, not proven. This is the frontier, and it’s where the marketing is sprinting ahead of the evidence. There is real, interesting research here. A 2024 meta-analysis found a positive effect of creatine on memory, with the strongest signal in older adults [3], however the same analysis rated the certainty of that memory effect as moderate, and the evidence for other cognitive domains as low. Mood effects, on the other hand, are mixed [4]. The honest summary is: creatine may support memory, the effect is probably clearest in people under some kind of stress (sleep deprivation, aging, low dietary intake) and it is nowhere near “creatine makes you will raise your IQ.” Keep that calibration in mind, because you’re about to see brands throw it out entirely.
The catch, part one: you’re paying for the marketing
Creatine monohydrate is one of the cheapest interventions in all of wellness. Bought as a plain powder, it runs somewhere around forty cents a day at the standard five-gram dose. I know because I bought a tub to try myself and did the math.
Now here’s what the same molecule costs dressed up in fancy clothes:
Legion creatine gummies: about $40 a month.
MindBodyGreen creatine (with taurine): $65 a month.
Create creatine gummies: $73 for a one-time purchase… or $58 if you agree to monthly autoshipments.
Same five grams of creatine at the core of each. The price difference is brand, format, and in one case the addition of another amino acid. Gummies in particular carry a heavy convenience premium and added ingredients such as tapioca powder, sugar, pectin and allulose.
And notice that Create pricepoint. Seventy-three dollars if you buy it once; fifty-eight if you hand over your recurring billing information. That fifteen-dollar gap is the whole subscription game in miniature: the “sale” price is contingent on a commitment most people forget they made. The sticker you see advertised is frequently the subscribed price, which means the real cost of trying it once is higher than advertised.
None of this makes these products scams, they are just expensive ways to buy a cheap molecule, and the more a brand leans on format and subscription to justify the price, the more it’s worth asking what you’re actually paying for.
The catch, part two: when the citation doesn’t say what they claim
This is the part that turned my head, and it’s the reason I care about this beyond price.
Good supplement marketing has learned to look evidence-based. Footnotes, superscripts, “clinically studied,” charts with citations underneath. The presence of a citation reads as rigor. But a citation is only as good as what’s actually in the paper cited and that’s something almost no one checks. So I checked.
One brand’s science page featured a chart titled “Memory Improvement With Creatine,” with a bold claim about a twenty percent boost in memory performance, sourced to a specific study. When I pulled that study, it was a resistance-training paper about muscle fiber adaptations. I searched the full text. It contains no measure of memory, no measure of cognition, and not even the age group shown on the chart. The citation is real. The paper exists. It simply has nothing to do with the claim it’s being used to support.
That’s a different thing from overselling. Overselling is stretching what a study found. This is attaching a real study to a finding it never made, on the exact claim — cognition — where the underlying scientific evidence is weakest. The footnote is doing the work of making an unsupported claim look sourced.
A subtler version of the same move: another brand supports its “creatine for your brain” messaging by citing a legitimate review of creatine’s role in cellular energy metabolism. That paper is real and correct as creatine genuinely helps regenerate ATP in high-demand tissue, including the brain. But “creatine is involved in brain energy metabolism” is a statement about mechanism, not a demonstration that taking creatine gummies measurably improves your memory. The citation is accurate; it’s just being asked to prove something it doesn’t prove. Mechanism dressed up as outcome.
To be fair (this matters, because the point isn’t that every brand is lying) one of the three brands I looked at has a genuinely solid reference list: real, mostly primary sources that broadly support its strength and performance claims. Its cognition claim was the weak spot, resting on a customer testimonial rather than a study. But credit where it’s due: honest sourcing for the claims that had it.
The lesson isn’t “never trust a cited claim.” It’s that a citation is a pointer, not a proof, and the pointer is worth following. When a brand shows you a chart with a study underneath, the useful question is not “is there a citation” but “does the citation say this.”
A word on “third-party tested” and other reassuring phrases
Because supplements aren’t reviewed by the FDA before they’re sold, third-party testing is genuinely valuable. It’s the closest thing to an outside check that a product contains what the label says and isn’t contaminated. But the phrase gets used loosely, and the tiers actually mean different things:
NSF Certified for Sport and Informed Sport are the strongest marks. They involve batch-level or full-program testing against banned substances, and you can verify them.
Informed Choice uses the same lab and methods as Informed Sport but tests monthly retail samples rather than every batch. Still legit, but a tier down.
A plain “NSF” mark is not the same as “NSF Certified for Sport,” and brands sometimes let you assume it is.
And “lab-tested,” “quality tested,” or an official-looking in-house badge with no named certifier behind it means whatever the brand wants it to mean. This is the brand cosplaying third-party testing.
One important caveat that fits everything above: third-party testing certifies that a product is what it says and is uncontaminated. It does not certify that the product works. It’s a purity check, not an efficacy stamp. The same way an ingredient being “generally recognized as safe” is a regulatory technicality, not the FDA vouching that it does anything. Don’t let a testing badge do the job of real bonafide evidence.
The verdict
Creatine monohydrate is a gift. Cheap, safe in healthy adults, and genuinely effective, especially for strength. A rare unambiguous win on a shelf full of overpriced hope.
The grift, where it exists, is in the packaging around it: the gummies at a multiple of the powder’s price, the subscriptions that make the “deal” contingent on the customer forgetting to cancel, the brain claims that outrun the evidence, and the footnotes that point to studies that don’t say what they’re cited for.
So here’s what to actually do, if creatine sounds like it might be for you:
Buy plain creatine monohydrate. Not the fancy “buffered” or “HCl” forms — they cost more and haven’t been shown to beat plain monohydrate. Skip the gummies unless you truly won’t take it otherwise.
Aim for about five grams a day. That’s the standard effective dose.
Pick the cheapest option that’s third-party tested — look for NSF Certified for Sport or Informed Sport specifically, or even Informed Choice (that’s what I went with). And match the certification to your actual risk: the every-batch, athlete-grade testing exists to protect drug-tested competitors. If that’s not you, a reputable tested tub is plenty; you don’t need to pay the athlete premium.
Skip anything that’s only “cheap” if you subscribe.
Creatine is the gift. Everything the marketing staples onto it is the part to watch.
Gift / Grift — evidence over hype. Every claim gets a citation; every figure is checked against a primary source before it runs.
