Once creatine enters the body or is produced within, it binds with a phosphate molecule to become creatine phosphate. ATP (adenosine tri-phosphate) is the body's primary energy source, driving various bodily processes. During the breakdown of carbs, proteins, or fats, ATP is generated. It functions by hydrolyzing a phosphate group, releasing energy used for processes like muscle contraction. This transforms ATP into ADP (adenosine di-phosphate), and is converted back into ATP.
Creatine plays a crucial role in this process by donating its phosphate group to ADP, replenishing ATP stores. Ultimately, creatine enhances ATP availability, facilitating longer and more intense training.
