Ribose is a pentose sugar found in all living cells and is a structural component of nucleotides such as DNA, RNA, and ATP.* ATP is the ultimate source of energy for all cells, and is necessary for all muscle movement.* Ribose has been clinically researched for its role in the support of adenosine triphosphate (ATP) production within skeletal muscle and for the maintenance of healthy cardiac energy metabolism.* These studies indicate that D-Ribose can help to sustain ATP production in these vital tissues.*
