Ribose occurs naturally in all living cells. It is a simple sugar that begins the metabolic process for ATP production. During strenuous exercise, large amounts of ATP, the body’s primary
energy-carrying molecule, can be depleted in heart and skeletal muscle cells. Ribose is used by the body to synthesize nucleotides, ATP, nucleic acids, and glycogen; it is thus indicated for recovery after sport and following intense and strenuous efforts.
