    Summary PsychonautWiki

    Citicoline (CDP-choline, cytidine 5'-diphosphocholine) is a water soluble nutrient which serves as a precursor to both choline and cytidine within the brain (which later converts to uridine). To humans, choline is an essential nutrient as its role in reducing the risk of neural tube defects, fatty liver disease, and other pathologies have been documented. CDP-choline is one of the three choline-containing phospholipids that can be orally supplemented (the other two being alpha-GPC and phosphatidylcholine).
