There's lots of misinformation on Creatine. It's generally sold for athletic and endurance purposes, but actually there's less proof of that effect than all the other researched uses for Creatine.

Creatine is thought to improve strength, increase lean muscle mass, and help the muscles recover more quickly during exercise. This muscular boost may help athletes achieve bursts of speed and energy, especially during short bouts of high-intensity activities such as weight lifting or sprinting. However, scientific research on creatine has been mixed. Although some studies have found that it does help improve performance during short periods of athletic activity, there is no evidence that creatine helps with endurance sports. Research also shows that not everyone's muscles respond to creatine; some people who use it see no benefit.

Despite the popularity of creatine among young people, there has been very little research conducted in children under age 18. Of those studies, a few have suggested a positive effect but the overall evidence is inconclusive.

Just because creatine is natural, doesn't necessarily mean that it is safe. Supplements aren't held to the same standards by the FDA as medications, which means you can't always know exactly what's in your supplement, or in what amounts.

Researchers still don't know the long-term effects of taking creatine supplements, especially in young people. Adolescents who take creatine often do so without their doctor's advice, which can cause them to take more than the recommended dose.

Although most healthy people can take it with no problem, creatine can, in rare cases, have adverse effects, particularly when used in excess. Side effects can include:

Weight gain
Anxiety
Breathing difficulty
Diarrhea
Fatigue
Fever
Headache
Kidney problems
Nausea, vomiting
Rash
Stomach upset

Certain drugs, including diabetes medications, acetaminophen, and diuretics, can have dangerous interactions with creatine. Taking the stimulants caffeine and ephedra with creatine can increase the risk of side effects.
