Creatine is the human body's natural source of energy for instant muscle movement. Creatine is produced on its own in our body from amino acids, and amino acids are the building blocks of protein. Creatine is found in a protein-rich non-plant diet, but it requires a lot of consumption to obtain a decent amount of Creatine. Creatine is stored in our muscles to have quick access for fast, high-intensity movements, like sprinting or powerlifting.
