Does Creatine Supplementation Improve Cognitive Performance?

Creatine is one of the most popular dietary supplements. As such, it has received considerable attention in scientific literature. As a dietary supple- ment it has consistently shown to increase anaerobic performance. It has been reported that creatine increases energy supplies to muscles and neu- rons. Because of its ability to supply energy to neurons, it has been hypoth- esized that creatine supplementation may improve cognitive function. Recently, researchers from the University of Edinburgh and the University of Sunderland collaborated on a project which examined the effects of cre- atine ethyl ester on performance during cognitive tasks. Thirty-four non- vegetarian subjects were recruited to be part of this investigation. Subjects were randomly assigned to either a placebo or creatine supplement group. Subjects in the creatine group consumed five grams of creatine or a maltodextrine placebo a day for two weeks depending upon their treat- ment group. Prior to, and after the 2-week treatment period, a series of cognitive function tests were completed. After supplementation, the creatine group demonstrated significant improvements in memory and tests of attention. Additionally, improvements in reaction time were noted after the 2-week creatine supplementation period. While this data is promising, it should be taken with caution as further scientific inquiry is necessary to further validate creatine’s ability to improve cognitive function.
