CDP Choline, also known as citicoline or cytidine diphosphate choline, is a precursor of phosphatidylcholine, glycerophosphatidylcholine, and acetylcholine. It is the product of the rate-limiting step of acetylcholine synthesis. Citicoline has well documented neuroprotective effects.^† It increases glutathione synthesis, augments glutathione reductase activity, and maintains mitochondrial cardiolipin levels.^† Citicoline supports memory, attention, and focus.^†
