Cytidine-5'-diphosphocholine is an intermediate in the biosynthesis of phosphatidylcholine (PC) and other structural phospholipids of cell membranes.

According to scientific studies, supplementation with CDP Choline

• increases the body’s PC production, affecting the composition of cell membranes
• has effects on various tissues, especially the nervous system
• increases cerebral metabolism
• alters the levels of neurotransmitters, such as dopamine
• decreases cocaine-craving during drug withdrawal
• is neuroprotective in cases of stroke and brain injury; accelerates recovery of motor control and improves memory and recall
• enhances learning ability in healthy “older subjects”
• has no serious side effects

A dose of 500 mg/day is normally used. The benefit in stroke recovery was only slightly better when 2000 mg/day was used. Amelioration of cocaine withdrawal was achieved with 500 mg twice per day.
