Uridine is a pyrimidine nucleoside composed of uracil and ribose that is readily taken up by the brain. This compound is synthesized de novo in mammals. It is found circulating in the blood and cerebrospinal fluid.

Uridine is an essential compound involved in maintaining cellular function and energy metabolism. It aids in multiple biological processes, including RNA synthesis, the synthesis of biomembranes, and glycosylation. Furthermore, uridine serves as a precursor molecule for UDP-glucose, a vital component in the synthesis and storage of glycogen in the liver. In addition, studies have shown that uridine reduces cytotoxicity and improves neurophysiological functions. It is involved in regulating various normal physiological processes in the body, including the cardio-circulatory, reproductive, peripheral and central nervous, and respiratory systems.
