what the evidence says

Creatine monohydrate is the best-evidenced sports supplement there is: a very large body of human trials consistently shows improved strength, power and lean mass alongside resistance training, with an excellent long-term safety record. Newer, smaller trials suggest modest cognitive benefits, particularly under sleep deprivation and in older adults. Practically everything works at 3-5g daily; loading is optional.
