Creatine is a natural amino acid commonly found in meat products and, also, produced in small amounts inside the human body. Nearly all (95%) of body creatine is stored in muscle cells where it is used to fuel short duration, high-intensity activities like sprinting, jumping, and weight training [1-3, 7, 11-15, 40, 41]. There have been numerous studies reporting beneficial effects of creatine supplementation, particularly when resistance training is included during supplementation.
Creatine monohydrate is one of the most heavily researched and scientifically validated ergogenic aids in sport. We’ll review its safety and supplementation strategies shown to improve athletic performance.
