Citicoline (CDP-choline) supplies choline and cytidine and supports the brain's phospholipid and acetylcholine systems, making it a popular focus and memory nootropic.
Some human trials, including in healthy adults and in age-related memory complaints, report modest improvements in attention and memory, and it is used clinically for cognition in some countries. The evidence is promising but early; it is one of the better-tolerated choline sources.
