The molecule adenosine triphosphate (ATP) provides the energy that directly powers muscle contraction. Logic would have us believe that if we provide the building blocks of ATP in supplements, muscle cells would have more ATP available and exercise performance would be enhanced. The adenosine in ATP can be made from the molecule inosine. However, adenosine concentrations in the cells seem to be tightly controlled and supplemented inosine is not efficiently converted to adeno-sine. Furthermore, it has been suggested that the processes necessary to break down the excessive inosine may generate free radicals. In addition, inosine is broken down to uric acid, which is involved in the formation of certain types of kidney stones and gout if not proficiently removed from the blood
