Cognizin Citicoline

CDP Choline is a compound made up of choline and cytidine with neuroprotective and nootropic activity. CDP Choline decreases age-related memory impairment and cognitive decline, and enhances attention, learning and memory.

Scientific Name:
Cytidine diphosphocholine


  • After ingestion, CDP Choline originates choline and cytidine, the latter then being converted into uridine[1]
  • Both choline and uridine are neuroprotective[1]
  • Choline is a nicotinic Acetylcholine receptor agonist[2]
  • Increases the production of acetylcholine, adrenalin and noradrenalin[1]
  • Increases the release of Dopamine by acting on dopamine transporters[3]
  • Increases phosphatidylcholine production in the brain – an important component of cell membranes[4]
  • Maintains neuronal membrane integrity and reduces neuronal death[4,5]
