ATP stands for adenosine 5’-triphosphate, your body’s natural energy source. Adenosine triphosphate exists in virtually every cell of the body and its role in energy function at the cellular level has been well established by science. ATP is generally manufactured in the body on a continual basis but age, exercise (weight training, sports) and other stressors can significantly reduce or deplete your ATP levels and this is where Palo Alto Lab’s ATP Tabs comes into play. When you are in the middle of your workout and you are straining for that last rep or trying to finish that last mile, the boost you receive from ATP Tabs will allow you to burst through it.
