The Study
Clinical pharmacology of the dietary supplement creatine monohydrate.
This study is like a summary of other people's reports about creatine — it doesn’t do any experiments itself. So it can say 'some people think creatine helps with muscles,' but it can’t say 'creatine definitely makes muscles stronger.'
Analysis score
Maximum 5 for a narrative review.
Where the score came from
Creatine is a natural substance in your body and in meat. When people take extra creatine as a supplement, their muscles store more of it, which helps them lift heavier, jump higher, and recover faster.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — this means athletes can train harder and build more muscle, and people with certain muscle or nerve diseases might feel less tired or weak.
- 2Creatine stores in muscles go up by 20–40% with 3–5g/day, leading to more strength, power, and muscle mass without changing fat mass.

Taking 3 to 5 grams of creatine every day can help your muscles store more energy, making you stronger, more powerful, and better at building muscle when you lift weights—without making you gain fat.
Your body makes creatine on its own, and you also get it from eating meat and fish — it’s not something you have to take as a supplement to have it in your body.
Taking creatine supplements might cause some unwanted side effects or might not even be made properly, so what’s in the bottle isn’t always what it claims to be.
People have tried giving creatine, a supplement often used by athletes, to patients with several serious muscle and brain diseases, and some studies say it helped them feel better.
Taking creatine supplements might help your muscles and brain store more energy, which could keep your cells from running out of power, help build muscle, stop muscle from breaking down, and keep your cell walls stable.
Taking creatine supplements might help athletes lift heavier, sprint faster, build more muscle, and feel less tired when doing short bursts of intense exercise.
