How people get it: Sold as a powder or capsules, usually as creatine monohydrate.
The basics
What it is
Your body makes some creatine, and you also get some from animal foods such as beef and salmon. Creatine supplements, usually creatine monohydrate, give much larger amounts than food does.

What people use it for
- Creatine supplements can increase strength, power, and the ability to contract muscles for maximum effort.
- It is helpful only for repeated short bursts of intense activity, such as sprinting and weight lifting.
- For endurance activities like distance running, it appears to have little value.

Side effects and risks
Creatine can cause weight gain because it tends to cause the body to hold water. Reported effects include weight gain from water retention, plus anecdotal (unconfirmed) reports of nausea, diarrhea, muscle cramps, muscle stiffness, and heat intolerance.

Who should be careful, and drug interactions
Most studies of these supplements included only conditioned athletes, so it is often unclear whether they apply to occasional exercisers. Safety of combination products cannot be predicted unless trials tested that particular combination.

Questions to ask your doctor
- Is Creatine a sensible option for me, given my health and the medicines I take?
- Could Creatine interact with any medicine or supplement I already take?
- What side effects should I watch for, and when should I stop or call you?
- Supplements aren't checked by the FDA before sale. Is there a brand or a third-party test seal you would trust?
- How would we tell whether it is helping, and when should we review it?
