Research suggests creatine can improve performance in repeated short bursts of intense activity for some people. Results vary, and the evidence does not show the same benefit for every sport or outcome.
Potential benefits
Here is what current public evidence supports for creatine—and the context a label or headline may leave out.
- May support repeated high-intensity efforts such as resistance training and sprint intervals.
- May help training adaptations when paired with an appropriate training program.
- Creatine monohydrate is the most extensively studied form; more expensive forms have not been shown to be superior.
Limits and unanswered questions
Creatine appears to offer little value for endurance activities that do not rely on short-term energy systems. It can increase body weight, often through increased water retention. It does not replace training, sleep, or nutrition.
Safety matters
Healthy adults have been studied, but people with kidney conditions, those taking medications, and anyone pregnant or under 18 should discuss use with a qualified health professional. Choose independently tested products when possible and follow label directions.
Frequently asked questions
Which form has the most research?
Creatine monohydrate is the most widely studied form. The NIH ODS review notes that other forms have not been proven superior for raising muscle creatine.
Does creatine help endurance running?
Evidence suggests little benefit for predominantly endurance activity; added body weight may be undesirable for some endurance athletes.
