- Climbing pet constant temperature heating padSource Naturals D-Ribose Chewable Tablets (30 count) #28713

During strenuous exercise, large amounts of ATP, the body's primary energy-carrying molecule, can be lost from the heart and skeletal muscle cells. D-Ribose is a simple 5-carbon monosaccharide, or pentose sugar, that is used by the body to synthesize nucleotides, nucleic acids, glycogen, and other important metabolic products. Supplemental d-ribose bypasses the rate limiting steps that are slow to replenish lost nucleotides, thus providing an efficient way to renew energy in a short amount of time.Suitable for vegetarians.
