Adenosine-5'-triphosphate (ATP) – an adenosine nucleoid containing the adenosine in a compound of three phosphorus groups, having an important role as co-enzyme in the metabolism of cells and provides transport of energy from the breakdown of high-energy phosphate bonds. The importance of the body re-synthesis of ATP in the cells (e.g. Creatine supplementation) makes, that most of supplements is set to increase its effectiveness.
Attempts to use ATP as a supplement to improve workout capacity, do not meet the assumptions as ATP administered orally probably does not reach the cells, due to prior decomposition to uric acid. According to reports from some ATP manufacturers, they managed to create a formula for excluding this obstacle. However, this is unverified information.
