Citicoline (CDP-Choline)
Citicoline (CAS 987-78-0), also called CDP-choline or cytidine 5′-diphosphocholine, is a naturally occurring nucleotide supplied as a white crystalline powder for cognitive-health supplements and functional beverages.

Identity
What it is.
Citicoline is an intermediate in the body's own synthesis of phosphatidylcholine, a main component of cell membranes. As an ingredient it is one of the best-known compounds in the cognitive-health category, used in focus, memory and healthy-ageing formulas.
We manufacture citicoline in its free form, which contains no sodium and delivers more citicoline per gram than the sodium salt. It is the form most often chosen for capsules, tablets and powders.
Also known as: CDP-Choline, Cytidine 5′-diphosphocholine, Cytidine diphosphate choline, Citicoline free base.

Questions
Citicoline: common questions.
What is citicoline?
Citicoline, or CDP-choline, is a naturally occurring compound made of cytidine and choline joined by a diphosphate bridge. The body makes it as a step in building phosphatidylcholine for cell membranes. Its CAS number is 987-78-0.
What is the difference between citicoline and citicoline sodium?
Citicoline (CAS 987-78-0) is the free form. Citicoline sodium (CAS 33818-15-4) is its sodium salt. The free form contains more citicoline per gram and no sodium; the sodium salt has a near-neutral pH in solution and is the form described in most pharmacopoeias.
Is citicoline the same as CDP-choline?
Yes. Citicoline is the international non-proprietary name for cytidine 5′-diphosphocholine, which is abbreviated CDP-choline.
Is citicoline soluble in water?
Yes. Citicoline is freely soluble in water, which makes it suitable for shots, drink mixes and ready-to-drink beverages as well as capsules and tablets.
