All of this sounds pretty good. However, just because it is a natural substance, does not automatically mean that it is safe. Remember that supplements are not held to the same standards by the FDA as medications. So you can't always know exactly what's in a supplement, or in what amounts, unless it is authenticated by a reliable, independent lab.
ConsumerLab is an independent laboratory that tests and evaluates supplements.
Though most healthy people can take creatine without problems, it can, in rare cases, have adverse effects, particularly when used in excess. It should be pointed out that researchers still don't know the long-term effects, especially in young people. One concern is that adolescents who take it often do so without their doctor's advice, which can result in taking more than the recommended dose.
I recommend always telling your personal physician about any supplements you are taking.
Personal note: I used it for a while several years ago and became somewhat stronger in most exercises. So I have to say that it worked as promised. My muscles also felt "fuller." There were no negative side effects. But because the long-term effects are still unknown, I don't use it now. Also, at my age additional bulk is no longer a priority with me. -LF
