Creatine Monohydrate

Creatine cognitive benefits are well-documented. The brain consumes enormous ATP and creatine increases phosphocreatine stores providing a rapid buffer during cognitively demanding tasks. A 2003 RCT in Psychopharmacology found 5g per day for 6 weeks significantly improved working memory and intelligence test scores. The effect is strongest under cognitive stress and in vegetarians with lower baseline creatine. Dose is 3 to 5g daily.
