Ribose is one of the necessary building blocks for the formation of ATP, the universal energy molecule in the body.* Physical stress can deplete ATP stores in cardiac and skeletal muscles. As the rate-limiting substrate in the synthesis of nucleotides, ribose plays a vital role in replenishing ATP, which helps to promote cellular energy, muscle recovery, and endurance.*"
