Is it safe to take creatine long-term? I've heard mixed things.
So I've been taking creatine for a while now, and I keep hearing rumors that it can mess with your kidneys or cause other health issues if you take it forever. But I've read some studies that say it's pretty safe. For example, a review in the Journal of the International Society of Sports Nutrition found no significant adverse effects with long-term use. Anyone got solid info on this? Should I be worried about taking it for years?
