If you have ever walked past creatine on a shelf and assumed it was for people who bench press twice your body weight, you have company. Creatine built its reputation in weight rooms, and most of the early research was done on young athletes chasing short bursts of power. Over the past decade, a different set of studies has accumulated in adults in their sixties and seventies. The picture that emerges is more useful than either the hype or the eye roll suggests, but only if you keep the outcomes separate: some have decent support, some are genuinely unsettled, and some have very little.
What Creatine Actually Does in Your Muscles
Your body makes some creatine on its own, and you take in more from meat and fish. Most of it ends up in skeletal muscle, where a portion is stored as phosphocreatine and helps regenerate ATP, the molecule your muscles spend during short, high-effort work. That is why creatine is associated with lifting and sprinting rather than long, steady miles. Nearly all of the human research uses creatine monohydrate, so that is the form to keep in mind as you read what follows.
Strength Is Where the Evidence Is Strongest
If you read one finding on this topic, make it this one. A 2026 meta-analysis published in Frontiers in Nutrition pooled 11 randomized trials in adults aged 60 and older, average age around 67, and found a small improvement in muscle strength when creatine was added to a resistance training program compared with the same training plus a placebo. The authors rated the certainty of that result as moderate, which in this literature is about as good as it gets. Small means small, though, and the analysis does not support stretching it into a larger practical claim.
The condition attached to that finding matters as much as the finding. The stronger evidence in older adults is for creatine added to resistance training, not creatine used in place of it. Participants in these trials were doing structured strength work, and creatine was measured against that same work without it. The strongest evidence in older adults comes from creatine used alongside structured strength training. These trials do not establish that supplementation alone reliably builds or maintains muscle.
Muscle Mass: Two Meta-Analyses, Two Answers
Strength and size are not the same outcome, and this is the point where the evidence stops agreeing with itself. That same 2026 Frontiers analysis examined muscle mass across six trials and found no statistically significant effect, rating the certainty as low. A separate 2025 meta-analysis in the European Review of Aging and Physical Activity, covering eight trials and 482 participants, did find a small significant increase in lean tissue mass when creatine was paired with resistance training.
Two careful reviews, two different answers. One possible contributor is which studies each included, since the Frontiers analysis restricted itself to adults aged 60 and over while the European review took in trials with a mean age of 50 and up. Different pools of trials, different statistical methods and a small underlying body of research can all pull results in different directions, and no single explanation settles it. The honest read is that creatine may modestly increase lean tissue mass in older adults who strength train, but the research is not yet consistent enough to say so with confidence.
Function and Memory Are Still Open Questions
Physical function, things like rising from a chair or walking speed, sits further down the evidence ladder. The 2026 analysis found no significant effect and rated the certainty as very low, drawing on only three studies. Cognition is thinner still, with sparse and mixed results in older adults, intervention trials that disagree with one another, and no consistent effect on general cognitive performance. None of this supports claims about preventing frailty, falls, dementia or cognitive decline, and any product making those claims is well ahead of the research.
What’s Actually in a Creatine Product
Supplement shelves hold two broad categories: plain creatine monohydrate, usually an unflavored single-ingredient powder, and combination formulas that put creatine alongside other compounds. That second group is where reading the label starts to matter.
Creatine+, from Elysium Health, is one example that carries lot-level third-party verification, with both current flavors listed as NSF Certified for Sport, a program that tests finished products for substances banned in sport and confirms that the label matches the container. A stick pack contains 5 grams of creatine monohydrate, which falls within the maintenance range commonly used in creatine research, plus 1.5 grams of calcium HMB, 500 IU of vitamin D3, 195 milligrams of calcium and 300 milligrams of pomegranate extract. Certification tells you a product has been independently tested and made under audited conditions. It says nothing about whether the formula works, whether it suits you, or whether it is better than a product without the seal.
That ingredient list is also the reason to be careful about transferring evidence. The strength research described above was done on creatine monohydrate, usually studied on its own, and it cannot be treated as evidence that a complete multi-ingredient formula produces the same outcomes. The creatine-monohydrate trials described here did not test the complete Creatine+ formula. HMB, vitamin D3 and the other ingredients have their own evidence bases, but their inclusion does not mean the finished combination produces a greater effect.
How Much, and Who Should Check First
Trials in older adults commonly use 3 to 5 grams a day, which describes what researchers have done rather than a number aimed at you. Without a loading phase, daily maintenance dosing can gradually increase muscle creatine stores over several weeks. Higher short-term loading protocols are sometimes used in research to raise stores faster, but they are not required to increase muscle creatine stores over time. A larger number on a label does not by itself establish greater effectiveness or better product quality.
Safety deserves the same precision. Creatine can raise serum creatinine, because creatinine is a breakdown product of creatine, which means your clinician should know you take it when interpreting a kidney function panel. That is context for reading a lab result, not a reason to dismiss one, and an elevated value still deserves proper evaluation. Studies in generally healthy adults at studied doses have not shown impaired kidney function, and that finding should not be extended to people who already have kidney disease or reduced kidney function. Controlled research has also not shown creatine to increase dehydration or muscle cramping in healthy adults under studied conditions, though some participants do report mild and usually temporary stomach upset.
Talk with your doctor before starting creatine if you have kidney disease or reduced kidney function, another relevant medical condition, if you are pregnant or breastfeeding, or if you take medication that affects kidney function.
The through-line worth carrying away is that creatine is not one claim but a set of claims with very different amounts of evidence behind them. Strength has the best support, and even there the effect is small and tied to the training that goes with it. Lean tissue mass is contested, and function and cognition remain open. If you are a runner in your sixties hoping to stay strong for longer, the strength program is doing the heavy lifting, and creatine is a possible addition to a routine you are already keeping rather than a shortcut around building one.
