Cytidine is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a β-N₁-glycosidic bond. Cytidine is a component of RNA.

If cytosine is attached to a deoxyribose ring, it is known as a deoxycytidine.

Dietary sources of cytidine

Dietary sources of cytidine include foods with high RNA (ribonucleic acid) content,^[1] such as organ meats, Brewer's yeast, as well as pyrimidine-rich foods such as beer. During digestion, RNA-rich foods are broken-down into ribosyl pyrimidines (cytidine and uridine), which are absorbed intact.^[1] In humans, dietary cytidine is converted into uridine, ^[2] which is probably the compound behind cytidine's metabolic effects.
