Creatine supplementation shows promise in enhancing short-term memory and reaction speed, particularly after sleep deprivation.

Interestingly, the notion that vegetarians gain more cognitive benefits from creatine is challenged by recent findings, indicating that brain creatine levels are not necessarily lower in vegetarians compared to omnivores.
