Citicoline (INN), also known as cytidine diphosphate-choline (CDP-Choline) and cytidine 5'-diphosphocholine is a psychostimulant/nootropic. It is an intermediate in the generation of phosphatidylcholine from choline.

Studies suggest that CDP-choline supplements increase dopamine receptor densities, [1] and suggest that CDP-choline supplementation can ameliorate memory impairment caused by environmental conditions.[2] Preliminary research at Harvard found that citicoline supplements help improve focus and mental energy and may possibly be useful in the treatment of attention deficit disorder.[3]

It is an ingredient in some energy drinks such as "5-Hour Energy" and is available as an over the counter nutritional supplement.

Cognizin is the consumer brand for Citicoline produced by Kyowa Hakko Bio. Co., Ltd. and marketed as a dietary supplement and food ingredient by Kyowa Hakko U.S.A.
