Creatine has a reputation as a hardcore “bodybuilder supplement,” which keeps a lot of people from considering it — but it’s actually one of the most researched supplements that exists, with a safety profile to match. Here’s an honest look at what it does.
What creatine actually is
Creatine is a compound your body already produces and stores mainly in muscle, where it helps regenerate energy during short, intense bursts of effort. Supplementing simply increases your body’s existing stores.
What it’s actually shown to do
Creatine is consistently associated with improved strength and power output during resistance training, and may support muscle maintenance as part of an active lifestyle. It’s one of the few supplements with this much consistent research behind it.
It’s not just for bodybuilders
Research has also explored creatine’s role in general muscle health as people age, and some early research looks at cognitive and brain health applications — though that evidence is still developing compared to its strength-training benefits.
Common myths worth addressing
Creatine does not damage healthy kidneys at normal doses, despite a persistent myth — though people with existing kidney conditions should check with a doctor first. Initial water retention in muscle is normal and not the same as unwanted fat gain.
How it’s typically used
A simple, consistent daily dose (rather than complicated “loading” protocols) is a common, well-tolerated approach — creatine monohydrate specifically has the most research behind it compared to other forms.
Who should check with a doctor first
Anyone with existing kidney issues, who is pregnant or nursing, or who takes medications affecting kidney function should talk to a doctor before starting creatine, as with any new supplement.
