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.
