What does creatine do?
Creatine as a dietary supplement increases physical performance
Supplemental creatine intake can increase the stores of creatine and creatine phosphate in muscle cells. This, in turn, improves performance during intense muscle exertion, leading to increased muscle growth and strength gains. The larger creatine phosphate pool also results in faster ATP regeneration, thus supporting recovery after intense exertion in both training and competition.
