Effects of Creatine Supplementation on Brain Function and Health

2022

While the vast majority of research involving creatine supplementation has focused on skeletal muscle, there is a small body of accumulating research which has focused on creatine and the brain. Preliminary studies indicate that creatine supplementation (and guanidinoacetic acid; GAA) has the ability to increase brain creatine content in humans. Further, creatine has shown some promise for attenuating symptoms of concussion, mild traumatic brain injury and depression but its effect on neurodegenerative diseases appears lacking. The purpose of this narrative review is to summarize the current body of research pertaining to creatine supplementation on total creatine and phophorylcreatine cont…
